What happens if 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 545i 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 545i 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?

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 2004 BMW 545i 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 545i tires?

In most cases, your nearby Firestone Complete Auto Care can handle your BMW 545i tire repair. Ultimately, the severity of the damage will determine if your tires can be repaired.

Why do the tires on my 545i keep losing air?

Your 545i tires might keep losing air due to a leaking valve stem, puncture or hole in the tire tread or sidewall, or damaged wheel.

Is it necessary to replace all four BMW 545i tires at once?

When replacing the tires on your 545i, 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 545i Tire

Urban areas are booming. New roads are being built, and old ones are getting a face lift. There's construction around every corner! That means more tire-damaging road debris and flat tires. If your 2004 BMW 545i 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 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 we determine that your 2004 BMW 545i tire can be safely repaired, we'll follow three basic steps to repair it: (1) Remove the tire from the wheel for inspection and repair, (2) use a filler to close up the puncture (this is to keep moisture from getting in), and (3) re-seal the inside lining of your tire so that air won’t escape.

When Is It Time for BMW 545i Tire Replacement?

Sometimes, 2004 BMW 545i tire damage calls for more than a repair. Tires with less than 2/32nd inch tread remaining can't be repaired, no matter how minor the damage. At this tread depth, the tire is worn out and must 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 two or more punctures that are less than 16 inches away from each other; 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. 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.

Do I Need a Tire Inspection for My BMW 545i?

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. Bring your 2004 BMW 545i in for a tire inspection so we can assess the damage and help keep you safe on the road.
