Can I drive my Porsche on a flat tire?

Driving on a flat tire is not a good idea. Your 928 engine will keep running with a flat tire, but you could damage your wheel by continuing to drive on a flat.

Will a temporary sealant fix my Porsche'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?

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 1991 Porsche 928 is intended for only a few days of use, so don’t use it as a substitute for getting your tire repaired.

Who can repair Porsche 928 tires?

Your local Firestone Complete Auto Care can carry out most Porsche 928 tire repairs, but the extent of the damage will determine if we are able to help.

What is causing the tires on my 928 to keep losing air?

Tire punctures, damaged wheels, and leaking valve stems are possible reasons for your 928 tires continuously losing air.

Can I replace just one or two tires on my Porsche 928?

When replacing the tires on your 928, 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 Porsche 928 Tire Repaired

Urban areas are booming. Roads are expanding. There's construction around every corner! New progress is exciting, but the road debris it leaves behind may mean trouble for your tires. Firestone Complete Auto Care is here for you when your 1991 Porsche 928 needs flat tire repair or inspection. 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. 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 we determine that your 1991 Porsche 928 tire can be safely repaired, we’ll get to work on the steps to fix it: (1) Remove the tire from the wheel for inspection and repair, (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.

When Is It Time for Porsche 928 Tire Replacement?

Not all 1991 Porsche 928 tire damage can be 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. Some tire issues are easy and straightforward to repair, but other kinds of tire damage can’t be properly repaired. Tire damage that can’t be repaired effectively include a tire with a puncture larger than ¼ inch 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.

Depending on what Porsche 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. 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.

Tire Inspection Services for Your Porsche 928

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. Stay ahead of potentially dangerous tire issues. Bring your 1991 Porsche 928 in for a tire inspection.
