2018 Toyota 4Runner Tire Information

Beyond the correct tire size, there are a couple of other factors to consider when buying Toyota 4Runner tires like where and how you drive, and what tire brand you trust most. Think about where you live (countryside vs. city vs. mountains) and the kind of unexpected weather you're likely to experience when evaluating your driving conditions. It's not uncommon for drivers in states that experience all four seasons to buy more than one set of tires. one set for winter, one set 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!

Driving style is next on the list to think about when buying tires. If you're a big off-roading fan who forges paths where others can't, you have very different needs than a long-distance commuter who sticks to the highway. Browse Toyota 4Runner tires online or come to your nearby Firestone Complete Auto Care for help selecting the tire that's right for you.

2018 Toyota 4Runner Tire Questions

  • How do I check the tread depth on my Toyota tires? Stay on top of your tire tread depth to help avoid a dangerous drive. You can check tread depth with a penny.

  • How often should you get a wheel alignment for your 4Runner?  Check your 4Runner owner's manual for Toyota's recommended interval. It's generally a good idea to check your alignment every 6,000 miles or 6 months, depending on which comes first.

Engine Q&A 2018 Toyota 4Runner

  • Why does the check engine light in my 4Runner turn on when I start my car? It's okay if your check engine light comes on when you first start your vehicle. This is a sign that your vehicle is testing its circuits. The light should go off shortly. Bring your vehicle in if it doesn't.
  • Why is my Toyota 4Runner making engine noise?  Strange under-the-hood noises can point to problems within your Toyota 4Runner engine. Tapping or knocking could mean you need an oil change. Whistling sounds could mean you have an intake leak or misaligned belt. Squealing may be caused by a loose fan belt, and grinding could be a sign that something is wrong with your brakes — not the engine.
  • What could damage my Toyota 4Runner 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.

  • Is temporary sealant bad for my Toyota's tires? A temporary sealant may be able to help you get to a repair location safely.

2018 Toyota 4Runner Oil Change Q&A

  • Why is the oil light on in my Toyota 4Runner?  Your Toyota 4Runner oil change reminder light might illuminate if it’s been too long since your last oil change. On the other hand, the oil pressure light might illuminate due to a clogged oil filter, a faulty oil pressure sensor, low engine oil levels, or a malfunctioning oil pump.
  • 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.

This can improve your fuel system’s performance (and therefore, your engine’s performance).

Common Engine Tune-Up Q&A for 2018 Toyota 4Runner

  • When should Toyota 4Runner spark plugs be replaced?  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 should I do if I see leaks under my 4Runner? Don't ignore puddles of fluid under your Toyota 4Runner. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.
  • How often should I clean my Toyota 4Runner fuel injectors? Factors like fuel type and driving conditions can affect how frequently you need to clean your 4Runner 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 2018 Toyota 4Runner

During the first few years you had your 2018 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. Perhaps your 4Runner feels bouncy, sways to one side, or makes an unusual noise when going over a speed bump. The first sign of problems is a good time to bring your 2018 Toyota 4Runner in for suspension and steering service. 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.

2018 Toyota 4Runner Steering & Suspension Questions

  • Why is my Toyota 4Runner bouncing so much?  If it feels like you’re on a trampoline every time your 4Runner 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 4Runner tilt forward 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 Toyota's 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.

2018 Toyota 4Runner A/C System FAQs

  • What’s making my 4Runner A/C put out warm 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.
  • 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 vehicle have to be moving for my 4Runner’s A/C to work?  Damaged or worn components in your 4Runner’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.

Transmission Services for 2018 Toyota 4Runner

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, a small transmission issue can put a big dent in your 4Runner’s performance. 2018 Toyota 4Runner transmission problems can show up as shifting delays, grinding when accelerating, the car shaking at any speed, or a burning smell or whistling sounds coming from under the hood.

2018 Toyota 4Runner Transmission Q&A

  • When should I have my 4Runner's transmission fluid checked or exchanged?  Maintaining your Toyota 4Runner transmission fluid is one of the best ways to maintain your transmission's health. A general rule of thumb is to have your transmission fluid checked and changed about every 30,000 to 60,000 miles, but that timeline can change if you're hard on your Toyota. Leaks or low transmission fluid are easy to spot and affordable to repair.
  • Is it possible for transmission fluid to leak from my Toyota 4Runner? Yes, your Toyota 4Runner can develop a transmission fluid leak. As your 4Runner 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.
  • Is it okay to drive a 4Runner with a transmission fluid leak?  Driving with a transmission fluid leak is not recommended. Transmission fluid is essential to the proper operation of the transmission system, and a leak can cause serious problems, including reduced performance, overheating, and potentially transmission failure.
