2011 Nissan Leaf Tire Information

Other than getting the proper tire size, there are a couple of other factors to consider when buying Nissan Leaf 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!) Many drivers who live in states that experience all four seasons choose to purchase two sets of tires: one for winter and one for summer. Other drivers buy one set of all-season tires instead. That way they don't have to return to the tire shop and their vehicle is always ready for sun, rain, and light snow!

Next, consider your driving style. If you're a diehard off-roader, you have very different tire needs than a highway commuter who doesn't leave the paved path. Visit your local Firestone Complete Auto Care for help selecting the tire that's right for you, or get started by browsing tires that fit your Nissan Leaf.

Questions About 2011 Nissan Leaf Tires

  • Is Nissan tire inflation important? Even a tiny decrease in tire pressure could impact your safety and fuel economy. Maintaining proper tire pressure can help increase fuel economy, improve braking time, and boost tire lifespan.
  • Why are there numbers on the side of my Nissan Leaf tires? Your tire sidewall numbers tell you the recommended load carrying capacity, speed rating, treadwear, traction, and tire size. Talk to a tire technician to learn how to read Nissan tire numbers.
  • Is there an easy way to check Nissan tire tread depth? 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 Leaf 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.

When your car has 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. Before we adjust the alignment of your 2011 Nissan Leaf, we’ll start by checking the current alignment angles. If needed, we'll adjust your wheel alignment angles to match Nissan recommendations.

2011 Leaf Nissan Steering & Suspension Services

When you first drove your 2011 Nissan Leaf, you probably enjoyed a smooth and steady ride. But these days, things are starting to feel a bit rough. Maybe your Leaf jolts, pulls to one side, or makes a weird sound when you drive over a speed bump or turn. The first sign of trouble is the best time to bring your 2011 Nissan Leaf in for steering and suspension services. We’ll get to the source of your car problems and, if your Leaf suspension system needs repair, we'll explain all of your options and the potential cost.

2011 Nissan Leaf Steering & Suspension Questions

  • Why is my Nissan Leaf bouncing excessively?  If it feels like you’re on a trampoline every time your Leaf 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 Leaf front end dip forward when I brake?  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.
  • Does tire pressure and tread depth impact 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.

2011 Nissan Leaf A/C Service Near You

Technicians at Firestone Complete Auto Care are ready to help you address your 2011 Nissan Leaf A/C problems. During this initial A/C performance check, we’ll look at the state of your 2011 Nissan Leaf’s 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.

When we perform an A/C repair on your 2011 Nissan Leaf, we’ll also do an A/C evacuation and recharge. To start this process, a technician will flush out the old refrigerant from your vehicle’s A/C system. Then, they’ll use Nissan’s specifications to evacuate the system. Finally, we’ll recharge the A/C system with new refrigerant.

Questions About 2011 Nissan Leaf A/C Systems

  • Why is my Leaf A/C blowing hot air?  An A/C blowing hot air has several possible root causes. There could be an issue with your compressor clutch, a blown fuse, a leak, or a clog in the expansion valve.
  • What can cause an A/C system leak?  A/C system leaks are often due to a combination of age and moisture. Rubber seals and gaskets naturally degrade over time, allowing refrigerant to exit and moisture to enter your Leaf's A/C system.
  • Why won’t my Leaf’s A/C cool the vehicle when the car is stopped?  Damaged or worn components in your Leaf’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.

2011 Nissan Leaf Transmission Service & Repairs

The transmission delivers power from the engine to the wheels so that you can drive on your terms. Because your transmission is responsible for converting the right amount of power into the right amount of speed, even the smallest transmission problems should be addressed right away. 2011 Nissan Leaf transmission problems can show up as shifting delays, jumping or grinding during acceleration, the car shaking at any speed, or a burning smell or whistling sounds coming from under the hood. Let Nissan Leaf transmission problems linger and you could see your fuel economy decrease or find that you can't drive your Leaf at all. Our technicians are trained to service 2011  Nissan Leaf transmission systems according to vehicle manufacturer recommendations. If you think there’s something wrong with your Leaf’s transmission, schedule an appointment at your local Firestone Complete Auto Care to help keep your engine running at peak performance.

2011 Nissan Leaf Transmission Questions & Answers

  • Does my Leaf's transmission fluid need to be inspected?  Caring for your Nissan Leaf’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 Leaf transmission fluid leak?  Yes. Nissan Leaf transmission fluid can leak over time and potentially cause transmission issues. Worn or damaged seals, a loose or damaged transmission pan, a cracked transmission housing, faulty transmission cooler lines, or an overfilled transmission could cause transmission fluid leaks.
  • Should I avoid driving my Nissan Leaf if there is a transmission fluid leak?  Driving your Leaf with a transmission fluid leak is highly discouraged. Transmission fluid is vital to the smooth operation of your transmission system, and a leak can put the entire system at risk. A transmission fluid leak may lead to decreased performance, overheating, and possibly even transmission failure.

2011 Nissan Leaf Inspections

Every service performed at Firestone Complete Auto Care includes a multi-point Courtesy Check. To start, one of our technicians will check the battery in your Nissan Leaf to find out how much charge is remaining on it. The check will continue with a visual inspection of your Nissan Leaf's lights, windshield wipers, filters, hoses, alignment, tires, fluid levels, and belts.

Every service performed at your nearest Firestone Complete Auto Care will include a Courtesy Check, but we also offer an in-depth Complete Vehicle Inspection for your 2011 Nissan Leaf.

With this inspection, we want to help you stay on top of any issues that may require preventative maintenance.

In some cities or states, you may be able to take care of your state inspection or safety test at your local Firestone Complete Auto Care. Specific requirements for these types of inspections vary by state.

Common 2011 Nissan Leaf Vehicle Inspection Questions

  • When does my Nissan Leaf need an inspection? It needs a check-up if something feels 'off' to you, the driver. Your Nissan Leaf could benefit from a Courtesy Check if it has any illuminated dashboard lights, you hear weird noises coming from any part, the engine doesn't start sometimes, or your vehicle pulls to one side.
  • My 2011 Nissan Leaf failed the state inspection test. Can you fix it? There's a good chance we can. Stop by for a full system inspection and we'll get to the root of the issue.
  • What's the ideal timing for a full vehicle inspection on my Nissan Leaf?  The best time to get a complete vehicle inspection for your Nissan Leaf is before going on a road trip for the peace of mind. Another great time is when something abnormal occurs, and you can't pinpoint the issue. You might notice new dashboard lights, hear strange noises from under the hood, or your steering wheel doesn't feel like it once did.

Radiator Service & Repair for 2011 Nissan Leaf

Regular, proactive service on the radiator in your 2011 Nissan Leaf is crucial to keep your engine in the best possible shape for years to come. In fact, Nissan recommends replacing coolant/antifreeze at specific intervals, but you can also take note of any signs your radiator is going bad. 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 Leaf cooling system. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks. From the radiator cap to the heater core, your 2011 Nissan Leaf is in good hands at Firestone Complete Auto Care.

2011 Nissan Leaf Radiator Q&A

  • Why is the coolant light on my Nissan dashboard on?  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 Leaf to overheat?  If your Nissan Leaf 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.
  • Why does the radiator in my Leaf sound like it’s rumbling or boiling? If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your Leaf. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
