About 2021 Nissan Sentra Tires

Beyond the correct tire size, there are a couple of other factors to consider when buying Nissan Sentra tires like where and how you drive, and what tire brand you trust most. When thinking about your driving conditions, consider where you live (mountains vs. city vs. countryside) and the kind of weather can catch you off-guard. (Watch out Tornado Alley!) Drivers in states that fully experience all four seasons often buy two sets of tires: one for summer and one for winter. Other drivers prefer the convenience of all-season tires. They make one trip to the tire shop and they're pretty much ready for rain, light snow, or sun!

Your personal driving style is the next factor to consider. If you're a diehard off-roader, you have very different tire needs than a highway commuter who doesn't leave the paved path. Talk to a tire technician at Firestone Complete Auto Care for help choosing the best tire for you, or start shopping for Nissan Sentra tires online.

We sell tires, but we also service them and care for all the around-the-wheel components. We're your one-stop shop for tire installation, rotation, and ongoing maintenance! Buy 2021 Nissan Sentra tires online and schedule your installation when it's convenient for you.

2021 Nissan Sentra Tire Q&A

  • Is Nissan tire inflation important? A small decrease in tire pressure can have a big impact on your driving. Maintaining proper tire pressure can help improve braking time, increase fuel economy, and boost tire lifespan.
  • What do the tire sidewall numbers mean for my Nissan Sentra? The numbers on your tire sidewall give you information about tire speed rating, traction, treadwear, tire size, and load carrying capacity. Chat with a tire technician to learn how to read the numbers on your Nissan tires!
  • Can I check the tread depth on my Nissan tires at home? Stay on top of your tire tread depth to help avoid a dangerous drive. You can check tread depth with a penny. Hold the penny so that Abraham Lincoln is facing you, then place your penny into a tread groove upside down. If you can see the top of Abe’s head, your tread is shallow and it might be time for new Nissan Sentra tires. Grab a penny. Hold the so that Abe Lincon's head is facing you and his hair is pointing toward the ground. Then, place the penny into a tread groove. If you can see the top of Abe’s head, your tread is shallow and it might be time for new Nissan Sentra tires.

You might have a strong and reliable engine in your Nissan  Sentra. But if you can't stop it, then it's scrap metal. Don't wait if you're experiencing brake squeaks or a loss of braking power.

  • What is the average lifespan of Sentra brake pads? Brake pads typically last about 30,000 to 40,000 miles. However, driving conditions can affect this range. Sticking to highway driving and braking smoothly can help extend the life of your brake pads, while towing heavy loads or frequently riding your brakes can shorten it.
  • Can brake fluid leak when my Sentra is off? Because your Sentra brake system is a closed hydraulic system, it should not leak brake fluid. However, if components in your brake system have worn out or been damaged, it might cause brake fluid to leak.

  • How concerning is a drivetrain malfunction in my Sentra? If your Sentra has a drivetrain malfunction, don't wait. Get it checked out by a professional mechanic.

Wheel Alignment for 2021 Nissan Sentra

An alignment involves making adjustments to your Nissan Sentra's suspension system, the connection between the vehicle and the wheels. In an alignment service, the individual angles of your tires are adjusted so that they come into contact with the road in just the right way — the way Nissan intended them to. When you bring in your 2021 Nissan Sentra, we’ll perform an alignment check first. If needed, we'll adjust your wheel alignment angles to match Nissan recommendations.

Answers to Nissan Sentra Alignment Questions

  • Are there road conditions that can hurt my Nissan Sentra alignment? Potholes and uneven roads can knock your car out of alignment, so stay aware of the road ahead and adjust your speed (or avoid these obstacles whenever it’s safely possible).
  • How often should you get a wheel alignment for your Sentra? It’s usually suggested you check your alignment about every 6,000 miles or 6 months (whichever occurs first). Still, you should reference your Sentra owner’s manual for Nissan's recommended interval.
  • Do you need to get your Sentra wheels aligned?  It’s not mandatory to get an alignment after installing new tires on your Sentra, but it can be a smart decision! Proper alignment from the jump can help improve handling, fuel efficiency, and tire wear.

Engine Q&A 2021 Nissan Sentra

  • Why does the check engine light come on when I start my Sentra? It’s usually normal for your check engine light to turn on upon ignition. This is just your Sentra testing its circuits. The dash light shouldn't stay on. If it does, you might want to bring your vehicle in for service.
  • Why does my Nissan engine sound different? Strange engine sounds can be a sign something’s off in your Nissan Sentra. Knocking or tapping could be a symptom of low oil. A high-pitched whistle could signal an intake leak or misaligned belt. Squealing can be traced back to a loose fan belt, and grinding might be a sign of brake problems rather than engine issues.
  • Are you unknowingly damaging your Nissan Sentra engine?  Some driving habits are not so great for your engine. These include driving on a near-empty gas tank, flooring the gas pedal while the car is in Park, or accelerating too quickly, too soon. Protect your engine’s performance and efficiency by distancing yourself from these habits.

Nissan Sentra Tire Repair Questions

  • Can I drive my Nissan on a flat tire? Driving on a flat or underinflated tire can put extra stress on your wheels and alignment. While it’s sometimes necessary to drive a short distance on a flat tire to get to a safe place, don’t take any other trips in your Sentra until you can have the flat tire repaired or replaced.
  • Is temporary sealant bad for my Nissan's tires? A temporary sealant may be able to help you get to a repair location safely. But temporary or emergency sealants could possibly damage TPMS sensors, and in some cases may even void the warranty on your Bridgestone or Firestone tires. If your tire needs extensive repair, sealant can add time and labor costs to the process.
  • What is causing the tires on my Sentra to keep losing air? Your Sentra tires might keep losing air due to a leaking valve stem, puncture or hole in the tire tread or sidewall, or damaged wheel.

2021 Nissan Sentra Maintenance Q&A

  • What should I do after hitting a pothole in my Nissan Sentra? Watch out for pothole damage. If your 2021 Sentra is pulling to one side or the other, your tires or suspension system could be calling out for help.
  • When does my Nissan Sentra need high mileage oil?  Got 75,000+ miles on the odometer? Consider high mileage motor oil.

It can help reduce oil consumption, smoke, and emissions from older Nissan Sentra engines.
  • Why are my Nissan dashboard lights on?  It's better to get them addressed as soon as possible. An illuminated dashboard light means something in your vehicle isn't functioning like it should.

Top Nissan SentraCar Battery Questions

Stop by for a complimentary battery check at your favorite Firestone Complete Auto Care and get a handle on your car battery’s health.
  • How long can I expect my car battery to last?  Car battery lifespan varies depending on a few factors, including driving conditions, accessories, how well it’s maintained, and the type of battery. On average, a car battery lasts about three to five years.
  • What is the white, crusty stuff around my Sentra’s battery post?  A chemical reaction between battery acid and the air can cause a white, crusty buildup to form on the terminals of your Sentra car battery.

2021 Nissan Sentra Oil Change Service

Your 2021 Sentra’s oil should be changed according to Nissan’s recommended oil change intervals. Outside of Nissan-recommended oil change intervals, your Sentra may need an oil change if your check engine light is on, you hear knock knock knock coming from the engine, sense an oil smell in the cabin, or notice an unusual amount of exhaust. You may also need an oil change more frequently than Nissan recommends if you haul heavy loads, frequent dusty roads, enjoy off-roading, or drive at low speeds for long distances.

Whether you need high mileage oil, synthetic oil, or conventional oil, you'll find the right 2021 Nissan Sentra motor oil at Firestone Complete Auto Care. Talk with a teammate and consult your owner's manual before picking a motor oil.

Make an appointment for an oil change service today and let the oil experts take care of your Sentra's engine.

2021 Nissan Sentra Oil Change Questions

  • What can cause the oil light on my Nissan Sentra to illuminate?  Your Nissan Sentra oil change reminder light may come on if you're overdue for an oil change. The oil pressure light will typically come on if the oil level in the engine is too low, the oil pump is failing, you have a clogged oil filter, or there's a faulty oil pressure sensor.
  • Can I change my Nissan oil on my own?  Changing your own oil isn't as convenient as you might think. It requires special tools and old oil must be disposed of properly. Having your oil professionally changed reduces the chances of something going wrong with the oil change, but also with your vehicle down the road.
  • Why is my Nissan Sentra spewing blue or gray exhaust smoke?  Your engine could be burning oil due to a leak.  It may be time for a pro to take a look. A leak can be caused by a variety of issues including faulty valve seals, blown piston rings, or damaged cylinder walls.

2021 Nissan Sentra Engine Tune-Ups & Maintenance

Routine engine tune-ups can bring power back to your Sentra. The Firestone Complete Auto Care location in your community offers several Nissan Sentra engine tune-up services. The standard Firestone Tune-Up is one service option. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. Another service option pays special attention to the filters in your Sentra. Specifically, we replace the fuel filter and air filter. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your Sentra's fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your Sentra: your vehicle’s maintenance record and mileage can determine which service is best. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

*Check with a teammate at Firestone Complete Auto Care for complete terms and conditions regarding warranties.

Questions About 2021 Nissan Sentra Engine Tune-Ups

  • Will it hurt my Nissan Sentra to drive with old spark plugs? When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.
  • What does a puddle underneath my Nissan Sentra mean? Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.
  • How often do Nissan Sentra fuel injectors need to be cleaned? Factors like fuel type and driving conditions can affect how frequently you need to clean your Sentra fuel injectors. Some manufacturers recommend a fuel system cleaning as part of routine maintenance, or as needed if your vehicle is showing signs of poor fuel system performance.

Suspension Service & Repair for 2021 Nissan Sentra

When you first drove your 2021 Nissan Sentra, you probably enjoyed a smooth and steady ride. Lately, though, your ride’s been feeling a little bumpy. Perhaps your Sentra feels bouncy, drifts to one side, or makes noise whenever you turn or drive over a speed bump. The first sign of problems is a good time to bring your 2021 Nissan Sentra in for steering and suspension repairs. We'll get to the root of the problem and, if steering and suspension service is needed, we’ll go over the services you need and how much they will cost before we do any work.

Questions About 2021 Nissan Sentra Steering & Suspension

  • Why is my Nissan Sentra bouncing excessively?  If it feels like you’re on a trampoline every time your Sentra goes over a bump or dip, you may have a problem with your struts or shocks. Faulty shocks and struts can’t properly absorb road bumps, leading to a bouncy ride.
  • Why does my Sentra's nose dive down when I hit the brakes?  When you brake, the forward momentum combined with your vehicle's weight sends a lot of force to the vehicle's front end. A bad suspension can cause all that weight and force to push the front end downward.
  • What role do tire pressure and tread depth play in my Nissan's suspension?  Proper tire care can reduce strain on the suspension system, and also alert you to the need for new tires. Uneven tire wear is one sign of steering and suspension system problems, but it can also contribute to more.

Convenient & Local 2021 Nissan Sentra A/C Service

Our technicians will work to solve your 2021 Nissan Sentra A/C problems to the best of their ability. In this A/C performance inspection, we’ll check out the current condition of your 2021 Nissan Sentra A/C system to evaluate what repairs are necessary (if any). This check will include an examination of system pressure, a visual inspection, and a leak test.

Let's say we repair your 2021 Nissan Sentra A/C system. We will also perform an A/C evacuation and recharge. To do this, one of our technicians will remove the refrigerant in your A/C system (if there is even any left to remove). Then, they’ll use Nissan’s specifications to evacuate the system. To finish, we’ll add new refrigerant to recharge the A/C system.

Frequently Asked Questions for 2021 Nissan Sentra A/C Systems

  • Why do I get hot air from my Sentra A/C? Maybe your A/C starts cool but then gets warm. Or maybe it never gets cold in the first place. Either way, your A/C troubles could be traced back to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak.
  • What causes A/C system leaks? To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your Sentra’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.
  • What is causing my Sentra’s A/C to only work when the car is in motion?  Damaged or worn components in your Sentra’s electrical or air conditioning system can cause the A/C to only work when the car is moving. You may be dealing with low coolant or a faulty cooling fan.

2021 Nissan Sentra Transmission Questions & Answers

  • Does my Sentra's transmission fluid need to be inspected?  Caring for your Nissan Sentra’s transmission fluid is a great way to help it perform. About every 30,000 to 60,000 miles is a good timeframe for having your transmission fluid inspected and perhaps changed. Service intervals can vary depending on how you use your Nissan, so check with your technician first. Luckily, leaks and low fluid levels are easy to spot and inexpensive to fix.
  • Can Nissan Sentra transmission fluid leak? Yes, your Nissan Sentra can develop a transmission fluid leak. As your Sentra ages, parts of the transmission system might wear out or break down, leading to a leak and possible transmission issues. Common causes of transmission fluid leaks include worn seals, a damaged transmission housing, a loose or cracked transmission pan, an overfilled transmission, or faulty transmission lines.
  • Can I drive my Nissan Sentra with a transmission fluid leak?  It’s not advisable to drive your Sentra if it’s leaking transmission fluid. Your transmission system needs transmission fluid to function properly, and a leak can lead to significant problems, such as overheating or reduced performance. You might even experience transmission failure.

Staying on top of routine radiator maintenance for your 2021 Nissan Sentra is crucial to keep your engine in the best possible shape for years to come. Nissan recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You might be driving around (or about to be stranded) with a failing radiator if you see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant.

At Firestone Complete Auto Care, we start by performing a thorough inspection of your Nissan Sentra cooling system. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks. When it comes to radiator service and repair, we’re here to give your 2021 Nissan Sentra the top-notch service it needs.

Questions About Nissan Sentra Radiators

  • Why is the coolant light on my Nissan dashboard on?  Your engine might be about to overheat. If your low coolant light is on, pull over in a safe area and wait for your engine temperature to go down. Once it’s safe to do so, bring your car to your nearest Firestone Complete Auto Care to have the coolant system inspected.
  • Why is my Sentra overheating?  Your Nissan Sentra engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.
  • What is making my Sentra radiator sound like it’s boiling or rumbling? There could be air pockets in your Sentra’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).
