What happens if I drive my GMC on a flat tire?

Driving on a flat tire is not a good idea. Your Terrain 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 GMC's flat tire?

Fast fixes are a mixed blessing. They’ll help you get your GMC Terrain 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.

Can’t I just keep my spare tire on for a while?

For starters, your spare tire is designed to go short distances at low speeds. It’s not built to withstand the rough toll that the road can take from everyday driving! Putting off tire repair can also cause uneven tire wear in the long run – which could lead to a potentially costly toll on your steering and suspension system.

Where can I get my GMC Terrain tires repaired?

Your nearest Firestone Complete Auto Care is equipped to handle most GMC Terrain tire repairs, but it depends on how severe the damage is.

Why do the tires on my Terrain keep losing air?

If your Terrain tires are always losing air, you may have a puncture, damaged wheel, or leaking valve stem.

Do I have to replace all four GMC Terrain tires at the same time?

Replacing all four tires on your Terrain is not always necessary. However, it is recommended that you replace tires in pairs or all four tires at the same time for safety and performance reasons. If you have two new tires and two worn tires, the worn tires may not grip the road as well as the new tires, which could cause your car to slide or lose control. Always refer to your vehicle owner’s manual since some vehicles require you to replace all four tires if there is a tread difference greater than 3/32”.

GMC Terrain Tire Repair

Cities are growing. New roads are being built, and old ones are getting a face lift. There's construction around every corner! New progress is exciting, but the road debris it leaves behind may mean trouble for your tires. Firestone Complete Auto Care is here for you when your 2020 GMC Terrain needs flat tire repair or inspection. Our tire technicians can determine whether it's safe to plug and patch the tire, or whether it needs to be replaced. We'll start by evaluating the state of wear, the location of damage, type of damage, and the size of the damage.

If your 2020 GMC Terrain tire puncture can be repaired, we'll follow three basic steps to repair it: (1) Separate the tire from the vehicle wheel, (2) use a filler to close up the puncture (this is to keep moisture from getting in), and (3) seal the inner liner with a repair unit to prevent air loss.

GMC Terrain Tire Replacement

Not all 2020 GMC Terrain tire damage can be repaired. Even if your tire damage is minor, if your tires have less than 2/32nd inch of tread remaining, a repair isn’t possible (or safe). At this tread depth, the tire is worn out and must be replaced. Other tire damage that can't be safely repaired includes a puncture in the tire that is ¼ inch or greater in diameter; a tire with a puncture or damage outside the tread area; a tire with multiple punctures that are less than 16 inches apart; and a tire with cuts or tread separation.

When your damaged tire can’t be repaired, consult GMC’s recommendations for replacing one, two, or all four of your tires. For vehicles with AWD, manufacturers recommend replacing all four tires simultaneously. This is because the AWD system can only function optimally when all tires are uniform. However, this may not be necessary if your remaining three tires are new. It’s possible that you will only need to replace the tire that’s damaged – just make sure it’s the same size, type, and brand as the rest of your tires. Still not sure how many tires to replace or what kind to buy? A trained tire technician at Firestone Complete Auto Care is ready and waiting to answer your questions.

GMC Terrain Tire Inspection

A flat tire? That’s pretty hard to ignore. But other tire damage? It’s not always obvious! Tire damage can also show itself through subtle symptoms, like dents in your wheel rims, excessive noise coming from the exhaust system, bumps or bulges in tire sidewalls, or even leaks underneath the car. Stay ahead of potentially dangerous tire issues. Bring your 2020 GMC Terrain in for a tire inspection.
