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 840i 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?

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?

Don't rely on your spare tire for too long. Your 2021 BMW 840i 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.

Where can I get my BMW 840i xDrive tires repaired?

In most cases, your nearby Firestone Complete Auto Care can handle your BMW 840i xDrive tire repair. Ultimately, the severity of the damage will determine if your tires can be repaired.

Why do the tires on my 840i xDrive keep losing air?

Your 840i 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 840i xDrive?

While it may not always be necessary to replace all four tires on your 840i xDrive, 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.

BMW 840i xDrive Tire Repair

Urban areas are booming. New roads are being built, and old ones are getting a face lift. It seems construction is everywhere these days! That means more tire-damaging road debris and flat tires. Firestone Complete Auto Care is here for you when your 2021 BMW 840i xDrive needs flat tire repair or inspection. 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 2021 BMW 840i xDrive 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) fill in the area that’s been punctured to prevent damage from moisture, and (3) re-seal the inside lining of your tire so that air won’t escape.

Tire Replacement for Your BMW 840i xDrive

Sometimes, 2021 BMW 840i 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 with a puncture larger than ¼ inch in diameter; a puncture in the tire sidewall (or anywhere else that’s not within the tread area); multiple punctures that are too close together (less than 16 inches between them); and a tire with tread separation or significant cuts.

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. 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. 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.

Do I Need a Tire Inspection for My BMW 840i xDrive?

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. Stop tire damage in its tracks. Start with a tire inspection on your 2021 BMW 840i xDrive.
