How soon should I have my flat tire repaired?

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

Is temporary sealant bad for my Pontiac's tires?

A temporary sealant may be able to help you get to a repair location safely. But temporary or emergency sealants could possibly damage TPMS sensors, and in some cases may even void the warranty on your Bridgestone or Firestone tires. If your tire needs extensive repair, sealant can add time and labor costs to the process.

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 1999 Pontiac Grand Prix 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 Pontiac Grand Prix tires repaired?

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

What is causing the tires on my Grand Prix to keep losing air?

Your Grand Prix 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 Pontiac Grand Prix tires at once?

Replacing all four tires on your Grand Prix is not always necessary. However, it is recommended that you replace tires in pairs or all four tires at the same time for safety and performance reasons. If you have two new tires and two worn tires, the worn tires may not grip the road as well as the new tires, which could cause your car to slide or lose control. Always refer to your vehicle owner’s manual since some vehicles require you to replace all four tires if there is a tread difference greater than 3/32”.

Repairing Your Pontiac Grand Prix Tire

City populations are exploding. New roads are being built, and old ones are getting a face lift. There's construction around every corner! 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 1999 Pontiac Grand Prix 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. We'll start by evaluating the state of wear, the location of damage, type of damage, and the size of the damage.

If a repair on your 1999 Pontiac Grand Prix tire is feasible and safe, 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.

Tire Replacement for Your Pontiac Grand Prix

Unfortunately, some 1999 Pontiac Grand Prix 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). 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 tire with a puncture or damage outside the tread area; multiple punctures that are too close together (less than 16 inches between them); and a tire with tread separation or significant cuts.

Sometimes, it's in your best interest to buy one, two, or four new tires depending on Pontiac's recommendation. For example, it’s usually recommended that you replace all four tires at the same time on AWD vehicles. Why? Because having four identical tires is vital for the AWD system to perform like it’s supposed to. 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. Your tire technician can help you decide how many tires to replace and the kind of tire to purchase.

Tire Inspection Services for Your Pontiac Grand Prix

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 1999 Pontiac Grand Prix.
