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 Gran Coupe 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 2021 BMW 840i Gran Coupe is intended for only a few days of use, so don’t use it as a substitute for getting your tire repaired.

Where can I get my BMW 840i Gran Coupe tires repaired?

Your local Firestone Complete Auto Care can generally take care of most BMW 840i Gran Coupe tire repairs. However, it depends on the severity of the damage.

What is causing the tires on my 840i Gran Coupe to keep losing air?

Can I replace just one or two tires on my BMW 840i Gran Coupe?

When replacing the tires on your 840i Gran Coupe, 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.

Get Your BMW 840i Gran Coupe Tire Repaired

Cities are growing. Roads are expanding. Everywhere you look, it seems construction is in progress! That means more tire-damaging road debris and flat tires. Firestone Complete Auto Care is here for you when your 2021 BMW 840i Gran Coupe needs flat tire repair or inspection. 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 your 2021 BMW 840i Gran Coupe tire puncture can be repaired, we'll follow three basic steps to repair it: (1) Take the tire off the wheel for easy inspection, (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 840i Gran Coupe

Not all 2021 BMW 840i Gran Coupe tire damage can be repaired. 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. This tread depth indicates that the tire is worn out, and needs to 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 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 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. 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 840i Gran Coupe

A flat tire? That’s pretty hard to ignore. But other tire damage? It’s not always obvious! 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 Gran Coupe.
