Can I drive my BMW on a flat tire?

Driving on a flat tire is not a good idea. Your 850i 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?

Temporary sealants will solve your problem… for a little bit. If you’ve seen temporary or emergency tire sealant before (it usually comes in a can), it can be tempting to turn to this as a solution for your flat tire. Keep in mind that these fixes could buy you some time to get to Firestone Complete Auto Care for a proper repair, but they could also cause some harm in the process (for example, damage to your TPMS). Plus, using a product like this could void your tire warranty.

How long can I drive my BMW on a spare tire?

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 1991 BMW 850i is intended for only a few days of use, so don’t use it as a substitute for getting your tire repaired.

Who repairs BMW 850i tires?

In most cases, your nearby Firestone Complete Auto Care can handle your BMW 850i tire repair. Ultimately, the severity of the damage will determine if your tires can be repaired.

Why do the tires on my 850i keep losing air?

Tire punctures, damaged wheels, and leaking valve stems are possible reasons for your 850i tires continuously losing air.

Do I have to replace all four BMW 850i tires at the same time?

It's important to consider replacing your 850i 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 850i Tire Repaired

Urban areas are booming. New roads are being built, and old ones are getting a face lift. It seems construction is everywhere these days! New progress is exciting, but the road debris it leaves behind may mean trouble for your tires. If your 1991 BMW 850i 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. To start, we’ll consider the location of tire damage, the type of issue, the size and scope of the damage, and the amount of wear on your tires.

If a repair on your 1991 BMW 850i tire is feasible and safe, the repair process is actually fairly simple: (1) Remove the tire from the wheel for inspection and repair, (2) fill the puncture to keep the moisture out, and (3) re-seal the inside lining of your tire so that air won’t escape.

Tire Replacement for Your BMW 850i

Sometimes, 1991 BMW 850i 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. Other tire damage that can't be safely repaired includes a tire puncture with a diameter bigger than ¼ inch; a puncture in the tire sidewall (or anywhere else that’s not within the tread area); a tire with multiple punctures that are less than 16 inches apart; 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. But, if you’ve recently replaced your tires and they don’t have significant wear, a new set might not be needed. It’s possible that you will only need to replace the tire that’s damaged – just make sure it’s the same size, type, and brand as the rest of your tires. 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 850i

A flat tire? That’s pretty hard to ignore. But other tire damage? It’s not always obvious! Inconspicuous issues like bulging sidewalls, exhaust noise, leaks, or bent rims may indicate issues that need immediate attention. Stop tire damage in its tracks. Start with a tire inspection on your 1991 BMW 850i.
