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 S15 until you can have the flat tire repaired or replaced.

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?

Don't rely on your spare tire for too long. Your 1990 GMC S15 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 can repair GMC S15 tires?

In most cases, your nearby Firestone Complete Auto Care can handle your GMC S15 tire repair. Ultimately, the severity of the damage will determine if your tires can be repaired.

Why do my S15 tires keep losing air?

Do all four tires on a GMC S15 have to be replaced at the same time?

When replacing the tires on your S15, 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.

Get Your GMC S15 Tire Repaired

Urban areas are booming. New roads are being built, and old ones are getting a face lift. It seems construction is everywhere these days! New progress is exciting, but the road debris it leaves behind may mean trouble for your tires. If the road has been rough on your 1990 GMC S15 tires, Firestone Complete Auto Care can help. 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. 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 S15 tire is feasible and safe, we’ll get to work on the steps to fix it: (1) Take the tire off the wheel for easy inspection, (2) fill in the area that’s been punctured to prevent damage from moisture, and (3) secure and seal the inner tire liner to ensure the tire is airtight.

GMC S15 Tire Replacement

Unfortunately, some 1990 GMC S15 tire damage can’t be effectively repaired. Tires with less than 2/32nd inch tread remaining can't be repaired, no matter how minor the damage. 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 puncture with a diameter bigger than ¼ inch; a puncture that lies outside the tire tread area; a tire with multiple punctures that are less than 16 inches apart; and a tire with tread separation or significant cuts.

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 vehicles with AWD, manufacturers recommend replacing all four tires simultaneously. This is because the AWD system can only function optimally when all tires are uniform. 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. Your tire technician can help you decide how many tires to replace and the kind of tire to purchase.

Tire Inspection Services for Your GMC S15

A flat tire is a surefire sign of tire damage, but other indicators of tire issues aren’t so easy to spot. 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. Bring your 1990 GMC S15 in for a tire inspection so we can assess the damage and help keep you safe on the road.
