What happens if I drive my BMW on a flat tire?

Driving on a flat tire is not a good idea. Your 740iL 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 BMW's flat tire?

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.

What’s the harm in using my spare tire for a while?

Don't rely on your spare tire for too long. Your 1999 BMW 740iL may come equipped with a compact spare tire. A spare is different than an everyday tire and is only designed to be driven a certain number of miles at lower speeds.

Who can repair BMW 740iL tires?

Your nearest Firestone Complete Auto Care is equipped to handle most BMW 740iL tire repairs, but it depends on how severe the damage is.

What is causing the tires on my 740iL to keep losing air?

Tire punctures, damaged wheels, and leaking valve stems are possible reasons for your 740iL tires continuously losing air.

Can I replace just one or two tires on my BMW 740iL?

It's important to consider replacing your 740iL tires in pairs or all four at once for safety and performance reasons, even if only two of them appear to be worn. If the remaining two tires are significantly newer, they may have different grip than the older tires, which can affect your vehicle’s handling. Always double-check your owner's manual since some vehicles require all four tires to be replaced if there's a tread difference of more than 3/32”.

Get Your BMW 740iL Tire Repaired

Cities are growing. 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. If your 1999 BMW 740iL is in need of a tire inspection or possible flat tire repair, Firestone Complete Auto Care has your back. 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 begin by taking a look at where the damage is, the type and extent of the tire damage, and how all of your tires are wearing.

If your 1999 BMW 740iL tire puncture can be repaired, we'll follow three basic steps to repair it: (1) Separate the tire from the vehicle wheel, (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.

BMW 740iL Tire Replacement

Sometimes, 1999 BMW 740iL 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). 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 a tire with cuts or tread separation.

When your damaged tire can’t be repaired, consult BMW’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. However, this may not be necessary if your remaining three tires are new. 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. Your tire technician can help you decide how many tires to replace and the kind of tire to purchase.

BMW 740iL Tire Inspection

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. Bring your 1999 BMW 740iL in for a tire inspection so we can assess the damage and help keep you safe on the road.
