Urban areas are booming. New roads are being built, and old ones are getting a face lift. 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 2018 BMW 540d xDrive 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 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 your 2018 BMW 540d xDrive tire puncture can be repaired, the repair process is actually fairly simple: (1) Take the tire off the wheel for easy inspection, (2) fill the puncture to keep the moisture out, and (3) seal the inner liner with a repair unit to prevent air loss.
Unfortunately, some 2018 BMW 540d xDrive 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). 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 with a puncture larger than ¼ inch in diameter; a tire with a puncture or damage outside the tread area; a tire with multiple punctures that are less than 16 inches apart; 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 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. 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.
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 2018 BMW 540d xDrive in for a tire inspection so we can assess the damage and help keep you safe on the road.
