Can I drive my BMW on a flat tire?

A flat tire that’s not addressed can take a terrible toll on the rest of your car. Until you have it repaired or replaced, drive your M850i xDrive as little as possible to reduce your risk of damage to the wheels and alignment – or further damage to that already struggling tire!

Can I use an emergency/temporary sealant to 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 2025 BMW M850i xDrive 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 M850i xDrive tire repair?

In most cases, your nearby Firestone Complete Auto Care can handle your BMW M850i xDrive tire repair. Ultimately, the severity of the damage will determine if your tires can be repaired.

What can cause M850i xDrive tires to keep losing air?

Your M850i xDrive tires might keep losing air due to a leaking valve stem, puncture or hole in the tire tread or sidewall, or damaged wheel.

Can I replace just one or two tires on my BMW M850i xDrive?

It's important to consider replacing your M850i xDrive 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”.

Repairing Your BMW M850i xDrive Tire

Urban areas are booming. New roads and buildings are springing up. It seems construction is everywhere these days! That means more tire-damaging road debris and flat tires. If the road has been rough on your 2025 BMW M850i xDrive 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 we determine that your 2025 BMW M850i xDrive tire can be safely repaired, the repair process is actually fairly simple: (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) secure and seal the inner tire liner to ensure the tire is airtight.

BMW M850i xDrive Tire Replacement

Sometimes, 2025 BMW M850i xDrive tire damage calls for more than a repair. 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. At this tread depth, the tire is worn out and must be replaced. If your tire is not yet worn down, there are other forms of damage that simply can’t be repaired, like a tire puncture with a diameter bigger than ¼ inch; 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 major cuts or separated treads.

Sometimes, it's in your best interest to buy one, two, or four new tires depending on BMW's recommendation. Manufacturers of AWD vehicles, for example, often recommend replacing all four tires at once because AWD systems need uniform tires to operate properly. 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 M850i xDrive 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. Stay ahead of potentially dangerous tire issues. Bring your 2025 BMW M850i xDrive in for a tire inspection.
