About 1991 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 where and how you drive, and what tire brand you trust most. When evaluating your driving conditions, think about where you live (countryside vs. city vs. mountains) and the kind of unexpected weather you're likely to experience. Drivers in states that fully experience all four seasons often buy two sets of tires: one for summer and one for winter. 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 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.

1991 Toyota 4Runner Tire Questions

  • Is Toyota 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 Toyota 4Runner 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 Toyota tire numbers.
  • Is there an easy way to check Toyota 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 Toyota 4Runner 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 Toyota 4Runner tires.

For example, mainly driving on highways and gradually braking can help increase the lifespan of your brake pads, and carrying hefty loads or riding your brakes can shorten it.

  • Why is my 4Runner malfunction indicator light (MIL) on? A multitude of problems can activate your 4Runner’s malfunction indicator light (better known as the check engine light), including issues with the engine, transmission, sensors, electrical system, or connectors.
  • How worried should I be about a drivetrain malfunction in my 4Runner?

1991 Toyota 4Runner Wheel Alignment

An alignment involves making adjustments to your Toyota 4Runner's suspension system, which serves to attach your wheels to your vehicle. 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 Toyota intended them to. When you bring in your 1991 Toyota 4Runner, we’ll perform an alignment check first. Then, we’ll adjust the angles as needed until they match recommended measurements from Toyota.

Questions About Toyota 4Runner Alignment

  • How frequently 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.
  • Do you need to get your 4Runner wheels aligned when you get new tires? While you don’t necessarily need to get an alignment when putting new tires on your 4Runner, it’s still a good idea.

1991 Toyota 4Runner Engine Q&A

  • Why does the check engine light in my 4Runner turn on when I start my car? 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.
  • Are Toyota 4Runner engine noises bad? 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.
  • What could damage a Toyota engine? Certain driving habits can damage your engine and should be avoided. These habits include 'running on fumes,' revving the engine while still in Park, or pushing 'the pedal to the metal' before the engine has warmed up.

1991 Toyota 4Runner Tire Repair

If we determine that your 1991 Toyota 4Runner tire can be safely repaired, the repair process is actually fairly simple: (1) Remove the tire from the wheel for inspection and repair, (2) fill in the area that’s been punctured to prevent damage from moisture, and (3) seal the inner liner with a repair unit to prevent air loss.

Frequently Asked Toyota 4Runner Tire Repair Questions

  • What happens if I drive my Toyota 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 4Runner until you can have the flat tire repaired or replaced.
  • Will a temporary sealant fix my Toyota's flat tire? Temporary sealants will solve your problem… for a little bit. If you’ve seen temporary or emergency tire sealant before (it usually comes in a can), it can be tempting to turn to this as a solution for your flat tire. Keep in mind that these fixes could buy you some time to get to Firestone Complete Auto Care for a proper repair, but they could also cause some harm in the process (for example, damage to your TPMS). Plus, using a product like this could void your tire warranty.

Oil Change Q&A for Your 1991 Toyota 4Runner

  • Can I change my Toyota 4Runner oil at home?  Changing engine oil at home isn’t as simple as it’s made out to be. You’ll have to figure out how to properly dispose of the oil and buy special tools.

1991 Toyota 4Runner Engine Tune-Up Q&A

  • What happens if my Toyota 4Runner spark plugs fail? When it’s time to replace the spark plugs, don’t delay.

Replace spark plugs on time or about every 30,000 miles or so.
  • 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.

1991 4Runner Toyota Steering & Suspension Services

When you first bought your 1991 Toyota 4Runner, you probably enjoyed a smooth and steady ride. Lately, though, your ride’s been feeling a little bumpy. Perhaps your 4Runner feels bouncy, leans 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 1991 Toyota 4Runner in for steering and suspension repairs. We’ll get to the source of your car problems and, if your 4Runner suspension system needs repair, we’ll go over the services you need and how much they will cost before we do any work.

1991 Toyota 4Runner Steering & Suspension Questions

  • Why is my Toyota 4Runner bouncing excessively?  If your shocks or struts are in bad shape, they can’t dampen road bumps like they should. This can cause your 4Runner to bounce more than usual.
  • What can cause the front end of my 4Runner to dip forward when I apply the brakes?  As you brake, the forward momentum of your 4Runner combined with its weight sends a ton of force to its front end. A damaged or worn suspension system can cause the front end to compress and dip even further.
  • What role do tire pressure and tread depth play in my Toyota'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 1991 Toyota 4Runner A/C Service

Our trained technicians will do what they can to solve your 1991 Toyota 4Runner A/C problems. During this initial A/C performance check, we’ll look at the state of your 1991 Toyota 4Runner’s A/C system to evaluate what repairs are necessary (if any).

Finally, we’ll recharge the A/C system with new refrigerant.

Frequently Asked Questions for 1991 Toyota 4Runner A/C Systems

  • Why do I get hot air from my 4Runner A/C? If your car’s air conditioning isn’t blowing cold air at all (or it tries, then turns warm), you could have a clogged expansion valve, a faulty compressor clutch, a leak, or a malfunctioning fuse in the system.
  • What can cause an A/C system 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?  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.

1991 Toyota 4Runner Transmission Service

Because your transmission is responsible for converting the right amount of power into the right amount of speed, a tiny transmission issue can take a major toll on your car’s performance. 1991 Toyota 4Runner 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.

1991 Toyota 4Runner Transmission Q&A

  • Does my 4Runner's transmission fluid need to be inspected?  Regularly checking and exchanging your 1991 4Runner’s transmission fluid is one of the best ways to help the transmission system perform. Some technicians would say that between 30,000 and 60,000 miles is a good timeframe for having your Toyota's transmission fluid checked and replaced, but that timeline can vary depending on how your vehicle is used and your manufacturer’s recommendations. The good news is that transmission fluid leaks are affordable to repair and easy to spot.
  • Can transmission fluid leak from my Toyota 4Runner?  Yes. Toyota 4Runner 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 Toyota 4Runner if there is 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.

1991 Toyota 4Runner Radiator Service

Regular, proactive service on the radiator in your 1991 Toyota 4Runner is crucial to keep your engine in the best possible shape for years to come.

If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Toyota 4Runner’s cooling system. Then, we’ll move on to a machine-powered coolant exchange. Finally, we’ll refill the flushed sealants, lubricants and chemicals, then do a pressure check to catch any possible leaks. From the heater core to the radiator cap, your 1991 Toyota 4Runner is in good hands at Firestone Complete Auto Care.

1991 Toyota 4Runner Radiator Q&A

  • 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.
  • My 4Runner overheated! What can cause that?  Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Toyota 4Runner engine to overheat.
  • My 4Runner radiator sounds like it's rumbling or boiling! What's up? If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your 4Runner. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
