How soon should I have my flat tire repaired?

Driving on a flat or underinflated tire can put extra stress on your wheels and alignment. While it’s sometimes necessary to drive a short distance on a flat tire to get to a safe place, don’t take any other trips in your G3500 until you can have the flat tire repaired or replaced.

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.

Can’t I just keep my spare tire on 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 1990 GMC G3500 is intended for only a few days of use, so don’t use it as a substitute for getting your tire repaired.

Where can I get my GMC G3500 tires repaired?

Your nearest Firestone Complete Auto Care is equipped to handle most GMC G3500 tire repairs, but it depends on how severe the damage is.

What can cause G3500 tires to keep losing air?

Your G3500 tires might keep losing air due to a leaking valve stem, puncture or hole in the tire tread or sidewall, or damaged wheel.

Can I replace just one or two tires on my GMC G3500?

While it may not always be necessary to replace all four tires on your G3500, 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 G3500 Tire Repaired

City populations are exploding. Roads are expanding. Everywhere you look, it seems construction is in progress! Unfortunately, this can mean a higher chance of a flat or damaged tire caused by debris in the road. If the road has been rough on your 1990 GMC G3500 tires, Firestone Complete Auto Care can help. Our tire technicians can determine whether it's safe to plug and patch the tire, or whether it needs to be replaced. 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 a repair on your 1990 GMC G3500 tire is feasible and safe, the repair process is actually fairly simple: (1) Separate the tire from the vehicle wheel, (2) fill in the area that’s been punctured to prevent damage from moisture, and (3) seal the inner liner with a repair unit to prevent air loss.

GMC G3500 Tire Replacement

Unfortunately, some 1990 GMC G3500 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). Tires with this tread depth or less are no longer safe, so it’s time to replace the damaged tire. 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); multiple punctures that are too close together (less than 16 inches between them); 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. 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. 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 G3500?

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. Stay ahead of potentially dangerous tire issues. Bring your 1990 GMC G3500 in for a tire inspection.
