What happens if I drive my Porsche 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 911 until you can have the flat tire repaired or replaced.

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 1999 Porsche 911 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 911 tires?

Your local Firestone Complete Auto Care can generally take care of most Porsche 911 tire repairs. However, it depends on the severity of the damage.

Why do my 911 tires keep losing air?

Possible reasons for your 911 tires continuously losing air include a leaking valve steam, wheel damage, and a puncture or hole in the rubber.

Do I have to replace all four Porsche 911 tires at the same time?

When replacing the tires on your 911, 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.

Porsche 911 Tire Repair

Urban areas are booming. Roads are expanding. Everywhere you look, it seems construction is in progress! That means more tire-damaging road debris and flat tires. If your 1999 Porsche 911 is in need of a tire inspection or possible flat tire repair, Firestone Complete Auto Care has your back. Our tire technicians can determine whether it's safe to plug and patch the tire, or whether it needs to be replaced. 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 Porsche 911 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) secure and seal the inner tire liner to ensure the tire is airtight.

When Is It Time for Porsche 911 Tire Replacement?

Unfortunately, some 1999 Porsche 911 tire damage can’t be effectively repaired. 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. This tread depth indicates that the tire is worn out, and needs to 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 in the tire sidewall (or anywhere else that’s not within 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.

When your damaged tire can’t be repaired, consult Porsche’s recommendations for replacing one, two, or all four of your tires. 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. 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 Porsche 911

Some tire issues can cause you to have a flat, but other damage isn't so noticeable right away. Inconspicuous issues like bulging sidewalls, exhaust noise, leaks, or bent rims may indicate issues that need immediate attention. Stay ahead of potentially dangerous tire issues. Bring your 1999 Porsche 911 in for a tire inspection.
