How soon should I have my flat tire repaired?

Driving on a flat tire is not a good idea. Your Sierra 1500 engine will keep running with a flat tire, but you could damage your wheel by continuing to drive on a flat.

Can I use an emergency/temporary sealant to 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.

What’s the harm in using my spare tire for a while?

Don't rely on your spare tire for too long. Your 2021 GMC Sierra 1500 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 Sierra 1500 tires?

Your local Firestone Complete Auto Care can generally take care of most GMC Sierra 1500 tire repairs. However, it depends on the severity of the damage.

What is causing the tires on my Sierra 1500 to keep losing air?

Possible reasons for your Sierra 1500 tires continuously losing air include a leaking valve steam, wheel damage, and a puncture or hole in the rubber.

Can I replace just one or two tires on my GMC Sierra 1500?

It's important to consider replacing your Sierra 1500 tires in pairs or all four at once for safety and performance reasons, even if only two of them appear to be worn. If the remaining two tires are significantly newer, they may have different grip than the older tires, which can affect your vehicle’s handling. Always double-check your owner's manual since some vehicles require all four tires to be replaced if there's a tread difference of more than 3/32”.

Repairing Your GMC Sierra 1500 Tire

Cities are growing. Roads are expanding. 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 2021 GMC Sierra 1500 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 we determine that your 2021 GMC Sierra 1500 tire can be safely repaired, we'll follow three basic steps to repair it: (1) Separate the tire from the vehicle wheel, (2) fill in the area that’s been punctured to prevent damage from moisture, and (3) re-seal the inside lining of your tire so that air won’t escape.

When Is It Time for GMC Sierra 1500 Tire Replacement?

Not all 2021 GMC Sierra 1500 tire damage can be repaired. For tires that have less than 2/32nd inch of tread left, a repair simply isn’t possible – even if the tire damage is minimal. At this tread depth, the tire is worn out and must be replaced. Other tire damage that can't be safely repaired includes a tire with a puncture larger than ¼ inch in diameter; a puncture that lies outside the tire 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.

When your damaged tire can’t be repaired, consult GMC’s recommendations for replacing one, two, or all four of your tires. Manufacturers of AWD vehicles, for example, often recommend replacing all four tires at once because AWD systems need uniform tires to operate properly. But, if you’ve recently replaced your tires and they don’t have significant wear, a new set might not be needed. 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 Sierra 1500 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. Bring your 2021 GMC Sierra 1500 in for a tire inspection so we can assess the damage and help keep you safe on the road.
