How soon should I have my flat tire repaired?

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!

Is temporary sealant bad for my GMC's tires?

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?

While this sounds great in theory, keep in mind that most spare tires are not designed for distance or speed. The compact spare tire that most likely sits inside your 2021 GMC Terrain is intended for only a few days of use, so don’t use it as a substitute for getting your tire repaired.

Who can repair GMC Terrain tires?

In most cases, your nearby Firestone Complete Auto Care can handle your GMC Terrain tire repair. Ultimately, the severity of the damage will determine if your tires can be repaired.

Why do the tires on my Terrain keep losing air?

Tire punctures, damaged wheels, and leaking valve stems are possible reasons for your Terrain tires continuously losing air.

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

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.

GMC Terrain Tire Repair

Urban areas are booming. Roads are expanding. Everywhere you look, it seems construction is in progress! That means more tire-damaging road debris and flat tires. If your 2021 GMC Terrain is in need of a tire inspection or possible flat tire repair, Firestone Complete Auto Care has your back. 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. We’ll begin by taking a look at where the damage is, the type and extent of the tire damage, and how all of your tires are wearing.

If your 2021 GMC Terrain tire puncture can be repaired, we'll follow three basic steps to repair it: (1) Remove the tire from the wheel for inspection and repair, (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.

When Is It Time for GMC Terrain Tire Replacement?

Unfortunately, some 2021 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 multiple punctures that are less than 16 inches apart; and major cuts or separated treads.

Sometimes, it's in your best interest to buy one, two, or four new tires depending on GMC's recommendation. For example, it’s usually recommended that you replace all four tires at the same time on AWD vehicles. Why? Because having four identical tires is vital for the AWD system to perform like it’s supposed to. However, this may not be necessary if your remaining three tires are new. You might be able to replace one tire as long as it's the same brand, type, and size as the other three. 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.

Tire Inspection Services for Your GMC Terrain

A flat tire is a surefire sign of tire damage, but other indicators of tire issues aren’t so easy to spot. Inconspicuous issues like bulging sidewalls, exhaust noise, leaks, or bent rims may indicate issues that need immediate attention. Stay ahead of potentially dangerous tire issues. Bring your 2021 GMC Terrain in for a tire inspection.
