How soon should I have my flat tire repaired?

Driving on a flat tire is not a good idea. Your 740i engine will keep running with a flat tire, but you could damage your wheel by continuing to drive on a flat.

Can I use an emergency/temporary sealant to fix my BMW's flat tire?

Fast fixes are a mixed blessing. They’ll help you get your BMW 740i to Firestone Complete Auto Care, but don’t count on them to keep you on the road for very long. Using a temporary sealant may also void a Bridgestone or Firestone tire warranty.

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 BMW 740i 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 BMW 740i tires?

Your local Firestone Complete Auto Care can carry out most BMW 740i tire repairs, but the extent of the damage will determine if we are able to help.

What can cause 740i tires to keep losing air?

If your 740i tires are always losing air, you may have a puncture, damaged wheel, or leaking valve stem.

Do I have to replace all four BMW 740i tires at the same time?

When replacing the tires on your 740i, 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 BMW 740i Tire

Cities are growing. New roads and buildings are springing up. Everywhere you look, it seems construction is in progress! 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 BMW 740i tires, Firestone Complete Auto Care can help. 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. 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 BMW 740i tire puncture can be repaired, the repair process is actually fairly simple: (1) Separate the tire from the vehicle wheel, (2) fill in the area that’s been punctured to prevent damage from moisture, and (3) seal the inner liner with a repair unit to prevent air loss.

BMW 740i Tire Replacement

Sometimes, 1999 BMW 740i tire damage calls for more than a repair. 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). 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 puncture in the tire that is ¼ inch or greater in diameter; a puncture that lies outside the tire tread area; a tire with multiple punctures that are less than 16 inches apart; and a tire with tread separation or significant cuts.

Depending on what BMW 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. But, if you’ve recently replaced your tires and they don’t have significant wear, a new set might not be needed. If you can replace your damaged tire with the same type, brand, and size as the others, you may be able to save costs and only purchase one replacement. Need help? A tire technician can walk you through the options and help you determine what’s best for your vehicle’s performance and longevity.

Tire Inspection Services for Your BMW 740i

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 BMW 740i in for a tire inspection.
