How soon should I have my flat tire repaired?

A flat tire that’s not addressed can take a terrible toll on the rest of your car. Until you have it repaired or replaced, drive your Grand Prix as little as possible to reduce your risk of damage to the wheels and alignment – or further damage to that already struggling tire!

Is temporary sealant bad for my Pontiac'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 Pontiac on a spare tire?

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 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?

Your local Firestone Complete Auto Care can generally take care of most Pontiac Grand Prix tire repairs. However, it depends on the severity of the damage.

What can cause Grand Prix tires to keep losing air?

If your Grand Prix tires are always losing air, you may have a puncture, damaged wheel, or leaking valve stem.

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”.

Get Your Pontiac Grand Prix 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 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. 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 1990 Pontiac Grand Prix tire is feasible and safe, we’ll get to work on the steps to fix it: (1) Remove the tire from the wheel for inspection and repair, (2) use a filler to close up the puncture (this is to keep moisture from getting in), and (3) secure and seal the inner tire liner to ensure the tire is airtight.

Pontiac Grand Prix Tire Replacement

Sometimes, 1990 Pontiac Grand Prix 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. Tires with this tread depth or less are no longer safe, so it’s time to replace the damaged tire. Other tire damage that can't be safely repaired includes a puncture in the tire that is ¼ inch or greater in diameter; a puncture that lies outside the tire tread area; multiple punctures that are too close together (less than 16 inches between them); and major cuts or separated treads.

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. However, this may not be necessary if your remaining three tires are new. 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. 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.

Do I Need a Tire Inspection for My Pontiac Grand Prix?

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. Bring your 1990 Pontiac Grand Prix in for a tire inspection so we can assess the damage and help keep you safe on the road.
