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

A flat tire that’s not addressed can take a terrible toll on the rest of your car. Until you have it repaired or replaced, drive your Terrain as little as possible to reduce your risk of damage to the wheels and alignment – or further damage to that already struggling tire!

Will a temporary sealant fix my GMC'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.

How long can I drive my GMC on a spare tire?

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.

Who offers GMC Terrain tire repair?

Your local Firestone Complete Auto Care can carry out most GMC Terrain tire repairs, but the extent of the damage will determine if we are able to help.

Why do my Terrain tires keep losing air?

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

Can I replace just one or two tires on my GMC Terrain?

When replacing the tires on your Terrain, it's best to err on the side of caution and replace them in pairs or all four at once. Worn tires can compromise your car's handling and braking, especially if they're paired with newer tires. Refer to your owner's manual to determine whether your vehicle requires all four tires to be replaced if there's a tread difference.

Repairing Your GMC Terrain Tire

City populations are exploding. New roads and buildings are springing up. It seems construction is everywhere these days! That means more tire-damaging road debris and flat tires. If the road has been rough on your 2018 GMC Terrain tires, Firestone Complete Auto Care can help. There’s a chance your tire could be plugged and patched (rather than replaced). Our technicians can inspect your tire and let you know if it is safe to repair. To start, we’ll consider the location of tire damage, the type of issue, the size and scope of the damage, and the amount of wear on your tires.

If a repair on your 2018 GMC Terrain tire is feasible and safe, we'll follow three basic steps to repair it: (1) Remove the tire from the wheel for inspection and repair, (2) fill the puncture to keep the moisture out, and (3) re-seal the inside lining of your tire so that air won’t escape.

Tire Replacement for Your GMC Terrain

Unfortunately, some 2018 GMC Terrain tire damage can’t be effectively 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. If your tire is not yet worn down, there are other forms of damage that simply can’t be repaired, like a puncture in the tire that is ¼ inch or greater in diameter; a puncture in the tire sidewall (or anywhere else that’s not within the tread area); a tire with two or more punctures that are less than 16 inches away from each other; and a tire with tread separation or significant cuts.

Sometimes, it's in your best interest to buy one, two, or four new tires depending on GMC's recommendation. 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. But, if you’ve recently replaced your tires and they don’t have significant wear, a new set might not be needed. 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! Bent tire rims, bulging tire sidewalls, leaks under your car, or noise from your exhaust system can all point to tire-related damage that should be addressed quickly. Stop tire damage in its tracks. Start with a tire inspection on your 2018 GMC Terrain.
