2021 Toyota 4Runner Tire Information

Beyond the correct tire size, there are a couple of other factors to consider when buying Toyota 4Runner tires like which tire brands you like most and where you drive. 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 set for winter, one set for summer. 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!

Driving style is next on the list to think about when buying tires. If you're an avid off-roader who yearns to pioneer new paths, you have very different tire needs than a highway commuter who doesn't hit the hills very often. Browse Toyota 4Runner tires online or come to your nearby Firestone Complete Auto Care for help selecting the tire that's right for you.

  • Can I check the tread depth on my Toyota 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 Toyota 4Runner tires. Grab a penny.

Wheel Alignment for 2021 Toyota 4Runner

An alignment involves making adjustments to your Toyota 4Runner's suspension system, which connects the wheels with the rest of the vehicle. When your car has an alignment service, your tire angles are adjusted according to measurements recommended by Toyota. Why? So that your tires can make contact with the road at the best possible angle. When you bring in your 2021 Toyota 4Runner, we’ll perform an alignment check first. After that, we can adjust your wheel alignment angles until they match Toyota’s recommended measurements.

2021 Toyota 4Runner Engine Q&A

  • Why does the check engine light come on when I start my 4Runner? Generally, your check engine light turning on upon ignition is not a bad thing. It’s just your 4Runner firing up its circuits. The light should turn off in a bit, but come see us if it doesn't.
  • Why does my Toyota engine sound different? Strange engine sounds can be a sign something’s off in your Toyota 4Runner. 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 Toyota 4Runner engine? Certain driving habits can hurt your engine. These habits include driving on an empty fuel tank, revving your engine while the vehicle is in Park, or slamming the gas pedal while the engine is still cold. Steer clear of these habits to help protect engine performance and efficiency.

2021 Toyota 4Runner Tire Repair

If your 2021 Toyota 4Runner is in need of a tire inspection or possible flat tire repair, Firestone Complete Auto Care has your back.

If your 2021 Toyota 4Runner tire puncture can be repaired, we'll follow three basic steps to repair it: (1) Remove the tire from the wheel for inspection and repair, (2) use a filler to close up the puncture (this is to keep moisture from getting in), and (3) re-seal the inside lining of your tire so that air won’t escape.

Frequently Asked Toyota 4Runner Tire Repair Questions

  • How soon should I have my flat tire repaired? Driving on a flat tire is not a good idea. Your 4Runner engine will keep running with a flat tire, but you could damage your wheel by continuing to drive on a flat.
  • Will a temporary sealant fix my Toyota's flat tire? Fast fixes are a mixed blessing. They’ll help you get your Toyota 4Runner to Firestone Complete Auto Care, but don’t count on them to keep you on the road for very long. Using a temporary sealant may also void a Bridgestone or Firestone tire warranty.
  • Why do my 4Runner tires keep losing air? Possible reasons for your 4Runner tires continuously losing air include a leaking valve steam, wheel damage, and a puncture or hole in the rubber.

2021 Toyota 4Runner Maintenance Q&A

  • What do I do if I hit a pothole in my Toyota 4Runner?  Check your car for pothole damage! If you’ve recently hit a pothole (or even if you don’t remember hitting one… they can be sneaky!) check your tire treads, tire sidewalls, and wheels for damage. Potholes can also knock your car out of alignment, so have your alignment checked if you suspect you’ve driven over a rough patch of road lately.

Commonly Asked Toyota 4Runner Battery Questions

Stop in for a free battery check at your nearest Firestone Complete Auto Care and learn more about your battery's charge.
  • How long do car batteries last?  A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.
  • What is the white, crusty stuff around my 4Runner’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 4Runner car battery. This buildup — known as corrosion — can impede the flow of electricity and cause a range of issues, from poor performance to premature battery failure.

2021 Toyota 4Runner Oil Changes

Toyota recommends changing your 2021 4Runner’s oil at regular intervals. Your 4Runner may need an oil change right away if your check engine/oil change light is on, you hear engine knocking, smell oil inside the vehicle, or see an excess amount of vehicle exhaust. You might need an oil change more frequently than what’s recommended by Toyota if you regularly haul heavy loads, drive in dusty terrain, go off-roading a lot, or go long distances at low speeds.

Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your Toyota 4Runner. Check your owner's manual and talk with a technician to select the right Toyota 4Runner oil, whether it's Quaker State® Advanced Durability™ conventional oil, Pennzoil® High Mileage Vehicle® motor oil, Pennzoil Platinum® Full Synthetic motor oil with PurePlus™ Technology, or Shell Rotella® heavy-duty engine oil. During an oil change, a technician will change your 4Runner's oil, replace and recycle your used oil and oil filter, check all of your other filters, top-off essential fluids, and perform a free inspection on the rest of your vehicle. Get professional engine care by making an oil change appointment for your 4Runner today.

2021 Toyota 4Runner Oil Change Q&A

  • What does it mean if my Toyota 4Runner oil light comes on?  Your Toyota 4Runner 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 Toyota 4Runner oil at home?  First off, changing your own oil isn’t as easy as you’d think. You’ll have to buy special tools and figure out a way to recycle the old oil properly. Getting a professional oil change reduces the risk of something going wrong during the service, but also helps your car perform down the road.
  • Why is my Toyota 4Runner 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.

Engine Tune-Up Service for Your 2021 Toyota 4Runner

Routine engine tune-ups can bring power back to your 4Runner. The Firestone Complete Auto Care location in your community offers several Toyota 4Runner engine tune-up services. The first is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. The second service focuses on your 4Runner's filters, specifically replacing the air filter and fuel 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 4Runner's fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Here’s something to remember when choosing services: the mileage and service history of your 4Runner can determine what kind of service it needs. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

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

Common Engine Tune-Up Q&A for 2021 Toyota 4Runner

  • When should Toyota 4Runner spark plugs be replaced?  Replace spark plugs on time or about every 30,000 miles or so. Without the spark of electricity created by spark plugs, your engine doesn’t have the combustion it needs to start — which could leave you stranded on the road. Always replace your spark plugs on time based on Toyota’s recommendations.
  • What do I do if I see a pool of liquid under my Toyota 4Runner? Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.
  • How often should I clean my Toyota 4Runner fuel injectors? There is no hard and fast rule on how often fuel injectors should be cleaned, and it can vary based on driving habits and fuel type. Some manufacturers may suggest including a fuel system cleaning in your regular maintenance schedule. Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

2021 4Runner Toyota Steering & Suspension Services

When you first bought your 2021 Toyota 4Runner, you and your passengers probably enjoyed a ride that was smooth and balanced. Lately, though, your ride’s been feeling a little bumpy. Maybe your 4Runner bounces, leans 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 Toyota 4Runner in for steering and suspension services. We’ll get to the source of your car problems and, if steering and suspension service is needed, we'll explain all of your options and the potential cost.

Questions About 2021 Toyota 4Runner Steering & Suspension

  • Why is my Toyota 4Runner bouncing excessively? Damaged struts or shocks can't dampen road bumps properly, causing your vehicle to feel like a trampoline after each dip or bump.
  • Why does my 4Runner front end dip forward when I brake?  The forward dip in the front end of your 4Runner when you brake is caused by the weight and momentum transferring to the front wheels. If your suspension system is in bad shape, it can fail to distribute this force, leading your front end to dip further downward.
  • Does tire pressure and tread depth impact my Toyota's suspension?  Keeping your tires properly inflated can help reduce strain on the suspension, and also help you notice when you need new tires. A tire that doesn't have an adequate amount of tread can't grip the road or function as well as the manufacturer intended.

Convenient & Local 2021 Toyota 4Runner A/C Service

Our trained technicians will do what they can to solve your 2021 Toyota 4Runner A/C problems. During an A/C performance check, we'll determine the condition of your 2021 Toyota 4Runner 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 Toyota 4Runner 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 Toyota’s specifications to evacuate the system. To finish, we’ll add new refrigerant to recharge the A/C system.

Questions About 2021 Toyota 4Runner A/C Systems

  • Why do I get hot air from my 4Runner 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.
  • How does my A/C system get a leak? 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 4Runner’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.
  • Why does my 4Runner’s A/C only work when the car is moving? There could be issues with one or more components in the air conditioning or electrical system. Your 4Runner may have a faulty cooling fan or low refrigerant.

2021 Toyota 4Runner Transmission Service

The transmission delivers power from the motor to your wheels so that you can drive at your desired speed. Because of the transmission’s responsibility to translate the right dose of power into the right amount of speed, a small transmission issue can put a big dent in your 4Runner’s performance. 2021 Toyota 4Runner transmission problems can show up as shifting delays, jumping or grinding during acceleration, the car shaking on the road, or whistling noises or a burning smell coming from beneath the hood. If you ignore Toyota 4Runner transmission issues you might notice your fuel economy decrease or find that your 4Runner isn’t working at all. Our technicians are trained to service 2021  Toyota 4Runner transmission systems according to vehicle manufacturer recommendations. Schedule an appointment at your local Firestone Complete Auto Care at the first sign of transmission problems to help keep your Toyota running for miles and miles.

2021 Toyota 4Runner Transmission Questions & Answers

  • Does my 4Runner's transmission fluid need to be inspected?  Caring for your Toyota 4Runner’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 Toyota, so check with your technician first. Luckily, leaks and low fluid levels are easy to spot and inexpensive to fix.
  • Can Toyota 4Runner transmission fluid leak?  Yes. Toyota 4Runner transmission fluid can leak as time passes, which may lead to transmission problems. Transmission fluid leaks are often caused by worn or damaged transmission components, such as the transmission pan, cooler lines, seals, or housing. An overfilled transmission may also be behind your transmission fluid leak.
  • Should I avoid driving my Toyota 4Runner if there is a transmission fluid leak?  It’s not advisable to drive your 4Runner 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.

At Firestone Complete Auto Care, we perform a multi-point Courtesy Check during any vehicle service.

Common Toyota 4Runner Radiator Questions

  • What does an illuminated coolant temperature light mean for my Toyota?  Pay attention to the temperature gauge and lights on your dashboard. If a low coolant warning light comes on or your dashboard temperature gauge keeps rising, it’s likely that your engine is about to overheat (and could leave you stranded on the road). Wait for the engine to cool down, then have your coolant system checked immediately at your nearest Firestone Complete Auto Care.
  • What is causing my 4Runner to overheat?  If your Toyota 4Runner engine overheats, it could be because of a clogged radiator, a damaged thermostat, a faulty cooling fan, a malfunctioning water pump, or low coolant levels.
  • What can cause a 4Runner radiator to make boiling or rumbling sounds?  Air pockets in your 4Runner’s cooling system may cause a rumbling or boiling noise. You could also have a clogged radiator or simply need to replace the radiator cap.
