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

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

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?

For starters, your spare tire is designed to go short distances at low speeds. It’s not built to withstand the rough toll that the road can take from everyday driving! Putting off tire repair can also cause uneven tire wear in the long run – which could lead to a potentially costly toll on your steering and suspension system.

Where can I get my GMC Safari tires repaired?

Your local Firestone Complete Auto Care can carry out most GMC Safari tire repairs, but the extent of the damage will determine if we are able to help.

Why do the tires on my Safari keep losing air?

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

Is it necessary to replace all four GMC Safari tires at once?

When replacing the tires on your Safari, 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.

Repairing Your GMC Safari Tire

Urban areas are booming. 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. Firestone Complete Auto Care is here for you when your 1999 GMC Safari needs flat tire repair or inspection. 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. We'll start by evaluating the state of wear, the location of damage, type of damage, and the size of the damage.

If your 1999 GMC Safari tire puncture can be repaired, the repair process is actually fairly simple: (1) Take the tire off the wheel for easy inspection, (2) fill the puncture to keep the moisture out, and (3) seal the inner liner with a repair unit to prevent air loss.

Tire Replacement for Your GMC Safari

Not all 1999 GMC Safari tire damage can be repaired. Tires with less than 2/32nd inch tread remaining can't be repaired, no matter how minor the damage. This tread depth indicates that the tire is worn out, and needs to be replaced. Other tire damage that can't be safely repaired includes a tire puncture with a diameter bigger than ¼ inch; a puncture in the tire sidewall (or anywhere else that’s not within 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 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. However, this may not be necessary if your remaining three tires are new. 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 Safari 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. Stay ahead of potentially dangerous tire issues. Bring your 1999 GMC Safari in for a tire inspection.
