Can I drive my BMW 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 645Ci until you can have the flat tire repaired or replaced.

Is temporary sealant bad for my BMW's tires?

Fast fixes are a mixed blessing. They’ll help you get your BMW 645Ci 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.

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

Don't rely on your spare tire for too long. Your 2004 BMW 645Ci 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 offers BMW 645Ci tire repair?

Your local Firestone Complete Auto Care can carry out most BMW 645Ci tire repairs, but the extent of the damage will determine if we are able to help.

Why do the tires on my 645Ci keep losing air?

Your 645Ci tires might keep losing air due to a leaking valve stem, puncture or hole in the tire tread or sidewall, or damaged wheel.

Do I have to replace all four BMW 645Ci tires at the same time?

Replacing all four tires on your 645Ci 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”.

BMW 645Ci Tire Repair

Urban areas are booming. 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 your 2004 BMW 645Ci is in need of a tire inspection or possible flat tire repair, Firestone Complete Auto Care has your back. 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. 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 a repair on your 2004 BMW 645Ci tire is feasible and safe, the repair process is actually fairly simple: (1) Take the tire off the wheel for easy inspection, (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 BMW 645Ci Tire Replacement?

Unfortunately, some 2004 BMW 645Ci tire damage can’t be effectively repaired. Tires with less than 2/32nd inch tread remaining can't be repaired, no matter how minor the damage. Tires with this tread depth or less are no longer safe, so it’s time to replace the damaged tire. 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 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.

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 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. Just replaced your tires and only one is damaged? You may not need to buy another new full set after all. 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.

BMW 645Ci Tire Inspection

A flat tire? That’s pretty hard to ignore. But other tire damage? It’s not always obvious! 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. Stop tire damage in its tracks. Start with a tire inspection on your 2004 BMW 645Ci.
