How soon should I have my flat tire repaired?

Driving on a flat tire is not a good idea. Your 840i xDrive engine will keep running with a flat tire, but you could damage your wheel by continuing to drive on a flat.

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.

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

Don't rely on your spare tire for too long. Your 2020 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?

Your nearest Firestone Complete Auto Care is equipped to handle most BMW 840i xDrive tire repairs, but it depends on how severe the damage is.

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

Possible reasons for your 840i xDrive tires continuously losing air include a leaking valve steam, wheel damage, and a puncture or hole in the rubber.

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

Replacing all four tires on your 840i xDrive is not always necessary. However, it is recommended that you replace tires in pairs or all four tires at the same time for safety and performance reasons. If you have two new tires and two worn tires, the worn tires may not grip the road as well as the new tires, which could cause your car to slide or lose control. Always refer to your vehicle owner’s manual since some vehicles require you to replace all four tires if there is a tread difference greater than 3/32”.

BMW 840i xDrive Tire Repair

City populations are exploding. Roads are expanding. There's construction around every corner! That means more tire-damaging road debris and flat tires. Firestone Complete Auto Care is here for you when your 2020 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. 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 your 2020 BMW 840i xDrive tire puncture can be repaired, 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) re-seal the inside lining of your tire so that air won’t escape.

Tire Replacement for Your BMW 840i xDrive

Sometimes, 2020 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. 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 that lies outside the tire tread area; a tire with multiple punctures that are less than 16 inches apart; and a tire with cuts or tread separation.

Depending on what BMW recommends for your car, you’ll want to consider purchasing one new tire, two new tires, or a new full set. 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. However, this may not be necessary if your remaining three tires are new. You might be able to replace one tire as long as it's the same brand, type, and size as the other three. Your tire technician can help you decide how many tires to replace and the kind of tire to purchase.

Tire Inspection Services for Your BMW 840i xDrive

A flat tire is a surefire sign of tire damage, but other indicators of tire issues aren’t so easy to spot. Bent tire rims, bulging tire sidewalls, leaks under your car, or noise from your exhaust system can all point to tire-related damage that should be addressed quickly. Bring your 2020 BMW 840i xDrive in for a tire inspection so we can assess the damage and help keep you safe on the road.
