What happens if 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 640i as little as possible to reduce your risk of damage to the wheels and alignment – or further damage to that already struggling tire!

Is temporary sealant bad for my BMW's tires?

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.

Can’t I just keep my spare tire on 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 2012 BMW 640i 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 640i tires?

Your nearest Firestone Complete Auto Care is equipped to handle most BMW 640i tire repairs, but it depends on how severe the damage is.

What is causing the tires on my 640i to keep losing air?

Your 640i 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 640i tires at the same time?

While it may not always be necessary to replace all four tires on your 640i, it’s advised you replace them in pairs or all at once to ensure optimal safety and performance. Having two new tires and two worn tires can put you at risk since the worn tires might not have as good of traction as the new ones. Reference your owner’s manual to see if you will need to replace all four tires due to a large difference in tread.

Repairing Your BMW 640i Tire

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 2012 BMW 640i 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 start by evaluating the state of wear, the location of damage, type of damage, and the size of the damage.

If a repair on your 2012 BMW 640i tire is feasible and safe, the repair process is actually fairly simple: (1) Separate the tire from the vehicle wheel, (2) fill the puncture to keep the moisture out, and (3) seal the inner liner with a repair unit to prevent air loss.

Tire Replacement for Your BMW 640i

Unfortunately, some 2012 BMW 640i tire damage can’t be effectively repaired. 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 tire with a puncture larger than ¼ inch in diameter; a tire with a puncture or damage outside the 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.

When your damaged tire can’t be repaired, consult BMW’s recommendations for replacing one, two, or all four of your tires. 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. 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 640i?

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 2012 BMW 640i.
