Choosing 2012 Toyota 4Runner Tires

Other than getting the proper 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!) It's not uncommon for drivers in states that experience all four seasons to buy more than one set 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!

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. Browse Toyota 4Runner tires online or come to your nearby Firestone Complete Auto Care for help selecting the tire that's right for you.

  • What causes a 4Runner’s malfunction indicator light (MIL) to illuminate?  The malfunction indicator light — also known as the check engine light — on your 4Runner can illuminate for a variety of reasons, including engine issues, electrical problems, damaged sensors, transmission problems, misfires, and faulty connections.

Questions About 2012 Toyota 4Runner Engines

  • Why does my Toyota engine sound different? Unusual noises can signal a problem with your Toyota 4Runner engine. Tapping or knocking could mean you're low on oil.

  • What could damage a Toyota engine? Certain driving habits can damage your engine and should be avoided.

  • Is temporary sealant bad for my Toyota'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.
  • Why do the tires on my 4Runner keep losing air? Tire punctures, damaged wheels, and leaking valve stems are possible reasons for your 4Runner tires continuously losing air.

Top Toyota 4RunnerCar 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? The typical 12-volt car battery may last three to five years, depending on the type of battery, the driving conditions, and how well the battery is maintained.
  • Why is there white, crusty buildup on my 4Runner’s battery post?  The white, crusty stuff that can accumulate around 4Runner car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.

Oil Changes for 2012 Toyota 4Runner

Your 2012 4Runner’s oil should be changed according to Toyota’s recommended oil change intervals. No matter the mileage, your 4Runner may need its oil changed ASAP if your check engine light is on, you hear knocking sounds coming from the engine, smell oil inside the car, or notice an unusual amount of exhaust. You might need an oil change more frequently than what’s recommended by Toyota if you regularly haul heavy loads, frequent dusty roads, go off-roading a lot, or go long distances at low speeds.

Your local Firestone Complete Auto Care has the right 2012 Toyota 4Runner motor oil: either synthetic or conventional.

2012 Toyota 4Runner Oil Change Questions

  • Why is the oil light on in my Toyota 4Runner?  The oil change light in your Toyota 4Runner could be triggered by an overdue oil change. However, if the oil pressure light is on, you may be dealing with low engine oil, a failing oil pump, a clogged oil filter, or a malfunctioning oil pressure sensor.
  • How hard is it to change Toyota 4Runner oil at home?  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 Toyota exhaust smoke gray or blue?  There could be an oil leak and your engine is burning oil. Time to have a qualified technician check things out. The leak could be caused by several issues like leaking valve seals, damaged piston rings, or worn cylinder walls.

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. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your 4Runner. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your 4Runner: your vehicle’s maintenance record and mileage can determine which service is best. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.

*Ask a Firestone Complete Auto Care teammate about full terms and conditions for warranties.

Questions About 2012 Toyota 4Runner Engine Tune-Ups

  • Will it hurt my Toyota 4Runner to drive with old spark plugs?  Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.
  • 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 do Toyota 4Runner fuel injectors need to be cleaned? The frequency at which car fuel injectors should be cleaned can vary depending on several factors, including the type of fuel used and the driving conditions. Some manufacturers generally recommend a fuel system cleaning as part of your general car maintenance, or as needed based on symptoms of poor fuel system performance.

Suspension Service & Repair for 2012 Toyota 4Runner

When you first bought your 2012 Toyota 4Runner, the ride was probably so smooth that you didn’t even think about it! Lately, though, your ride’s been feeling a little bumpy. Perhaps your 4Runner feels bouncy, pulls to one side, or makes a weird sound when you drive over a speed bump or turn.

We’ll get to the source of your car problems and, if your 4Runner suspension system needs repair, we'll explain all of your options and the potential cost.

2012 Toyota 4Runner Steering & Suspension Questions

  • 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.
  • What can cause the front end of my 4Runner to dip forward when I apply the brakes?  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 treadwear and tire pressure impact my 4Runner's steering and suspension?  Maintaining your tires can help reduce strain on the suspension, nd also let you know when it's time to replace your tires. A faltering steering and suspension system could lead to uneven tire wear.

Convenient & Local 2012 Toyota 4Runner A/C Service

To finish, we’ll add new refrigerant to recharge the A/C system.

Questions About 2012 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?  Over the years, the rubber seals and gaskets in your 4Runner’s A/C system naturally degrade. Moisture can get into the system and cause a malfunction, or parts can simply wear out so that your system no longer seals properly.
  • What is causing my 4Runner’s A/C to only work when the car is in motion?  A problem with one or more of your air conditioning or electrical system components could cause the A/C to only work when your 4Runner is moving. You may be low on refrigerant, or the cooling fan could be faulty.

2012 Toyota 4Runner Transmission Service & Repairs

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.
  • Is it possible for transmission fluid to leak from my Toyota 4Runner?  Over time, transmission fluid can leak from your Toyota 4Runner, potentially causing transmission problems. A transmission fluid leak may be caused by a damaged transmission pan, faulty transmission cooler lines, worn-out seals, a cracked transmission housing, or an overfilled transmission.
  • Can I drive my Toyota 4Runner with a transmission fluid leak?  You should avoid driving with a transmission fluid leak. Your transmission system relies on transmission fluid to operate properly, and a leak may decrease performance, cause your 4Runner to overheat, or even lead to transmission failure.
