How soon should I have my flat tire repaired?

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 GLS550 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 Mercedes-Benz'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.

Can’t I just keep my spare tire on for a while?

Don't rely on your spare tire for too long. Your 2018 Mercedes-Benz GLS550 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.

Who repairs Mercedes-Benz GLS550 tires?

Your local Firestone Complete Auto Care can generally take care of most Mercedes-Benz GLS550 tire repairs. However, it depends on the severity of the damage.

Why do the tires on my GLS550 keep losing air?

If your GLS550 tires are always losing air, you may have a puncture, damaged wheel, or leaking valve stem.

Can I replace just one or two tires on my Mercedes-Benz GLS550?

It's important to consider replacing your GLS550 tires in pairs or all four at once for safety and performance reasons, even if only two of them appear to be worn. If the remaining two tires are significantly newer, they may have different grip than the older tires, which can affect your vehicle’s handling. Always double-check your owner's manual since some vehicles require all four tires to be replaced if there's a tread difference of more than 3/32”.

Repairing Your Mercedes-Benz GLS550 Tire

Urban areas are booming. New roads are being built, and old ones are getting a face lift. There's construction around every corner! New progress is exciting, but the road debris it leaves behind may mean trouble for your tires. Firestone Complete Auto Care is here for you when your 2018 Mercedes-Benz GLS550 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 a repair on your 2018 Mercedes-Benz GLS550 tire is feasible and safe, 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) secure and seal the inner tire liner to ensure the tire is airtight.

Tire Replacement for Your Mercedes-Benz GLS550

Unfortunately, some 2018 Mercedes-Benz GLS550 tire damage can’t be effectively 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. 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 puncture with a diameter bigger than ¼ inch; 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 Mercedes-Benz’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. Just replaced your tires and only one is damaged? You may not need to buy another new full set after all. You might be able to replace one tire as long as it's the same brand, type, and size as the other three. 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.

Tire Inspection Services for Your Mercedes-Benz GLS550

Some tire issues can cause you to have a flat, but other damage isn't so noticeable right away. 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. Stay ahead of potentially dangerous tire issues. Bring your 2018 Mercedes-Benz GLS550 in for a tire inspection.
