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!

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.

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

Don't rely on your spare tire for too long. Your 2012 GMC Terrain may come equipped with a compact spare tire. A spare is different than an everyday tire and is only designed to be driven a certain number of miles at lower speeds.

Who repairs GMC Terrain tires?

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.

What is causing the tires on my Terrain to 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?

While it may not always be necessary to replace all four tires on your Terrain, it’s advised you replace them in pairs or all at once to ensure optimal safety and performance. Having two new tires and two worn tires can put you at risk since the worn tires might not have as good of traction as the new ones. Reference your owner’s manual to see if you will need to replace all four tires due to a large difference in tread.

GMC Terrain Tire Repair

Urban areas are booming. New roads and buildings are springing up. Everywhere you look, it seems construction is in progress! 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 2012 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. 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 your 2012 GMC Terrain tire puncture can be repaired, the repair process is actually fairly simple: (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) re-seal the inside lining of your tire so that air won’t escape.

When Is It Time for GMC Terrain Tire Replacement?

Sometimes, 2012 GMC Terrain tire damage calls for more than a repair. Tires with less than 2/32nd inch tread remaining can't be repaired, no matter how minor the damage. Tires with this tread depth or less are no longer safe, so it’s time to replace the damaged tire. 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 two or more punctures that are less than 16 inches away from each other; and major cuts or separated treads.

Depending on what GMC recommends for your car, you’ll want to consider purchasing one new tire, two new tires, or a new full set. 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. Just replaced your tires and only one is damaged? You may not need to buy another new full set after all. 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.

GMC Terrain Tire Inspection

Some tire issues can cause you to have a flat, but other damage isn't so noticeable right away. 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 2012 GMC Terrain.
