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

Driving on a flat tire is not a good idea. Your Sierra 3500 HD 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?

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?

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 Sierra 3500 HD 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 Sierra 3500 HD tires?

In most cases, your nearby Firestone Complete Auto Care can handle your GMC Sierra 3500 HD tire repair. Ultimately, the severity of the damage will determine if your tires can be repaired.

What can cause Sierra 3500 HD tires to keep losing air?

Possible reasons for your Sierra 3500 HD tires continuously losing air include a leaking valve steam, wheel damage, and a puncture or hole in the rubber.

Do I have to replace all four GMC Sierra 3500 HD tires at the same time?

While it may not always be necessary to replace all four tires on your Sierra 3500 HD, 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.

Get Your GMC Sierra 3500 HD Tire Repaired

Urban areas are booming. New roads and buildings are springing up. Everywhere you look, it seems construction is in progress! That means more tire-damaging road debris and flat tires. If your 2021 GMC Sierra 3500 HD is in need of a tire inspection or possible flat tire repair, Firestone Complete Auto Care has your back. In some cases, a tire doesn’t have to be replaced – it can be plugged and patched with a simple repair. Depending on the damage, though, a repair might not be the right move. Our technicians can determine which option is best for your situation. 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 2021 GMC Sierra 3500 HD tire is feasible and safe, the repair process is actually fairly simple: (1) Remove the tire from the wheel for inspection and repair, (2) fill the puncture to keep the moisture out, and (3) seal the inner liner with a repair unit to prevent air loss.

GMC Sierra 3500 HD Tire Replacement

Sometimes, 2021 GMC Sierra 3500 HD tire damage calls for more than a repair. 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. If your tire is not yet worn down, there are other forms of damage that simply can’t be repaired, like a tire with a puncture larger than ¼ inch 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 a tire with cuts or tread separation.

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. Manufacturers of AWD vehicles, for example, often recommend replacing all four tires at once because AWD systems need uniform tires to operate properly. 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. Need help? A tire technician can walk you through the options and help you determine what’s best for your vehicle’s performance and longevity.

Do I Need a Tire Inspection for My GMC Sierra 3500 HD?

Some tire issues can cause you to have a flat, but other damage isn't so noticeable right away. 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. Stop tire damage in its tracks. Start with a tire inspection on your 2021 GMC Sierra 3500 HD.
