What happens if I drive my Mercedes-Benz on a flat tire?

Driving on a flat tire is not a good idea. Your GLS450 engine will keep running with a flat tire, but you could damage your wheel by continuing to drive on a flat.

Is temporary sealant bad for my Mercedes-Benz'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?

For starters, your spare tire is designed to go short distances at low speeds. It’s not built to withstand the rough toll that the road can take from everyday driving! Putting off tire repair can also cause uneven tire wear in the long run – which could lead to a potentially costly toll on your steering and suspension system.

Where can I get my Mercedes-Benz GLS450 tires repaired?

In most cases, your nearby Firestone Complete Auto Care can handle your Mercedes-Benz GLS450 tire repair. Ultimately, the severity of the damage will determine if your tires can be repaired.

What can cause GLS450 tires to keep losing air?

Tire punctures, damaged wheels, and leaking valve stems are possible reasons for your GLS450 tires continuously losing air.

Do all four tires on a Mercedes-Benz GLS450 have to be replaced at the same time?

While it may not always be necessary to replace all four tires on your GLS450, 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.

Repairing Your Mercedes-Benz GLS450 Tire

Cities are growing. New roads are being built, and old ones are getting a face lift. It seems construction is everywhere these days! 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 2020 Mercedes-Benz GLS450 needs flat tire repair or inspection. In some cases, a tire doesn’t have to be replaced – it can be plugged and patched with a simple repair. Depending on the damage, though, a repair might not be the right move. Our technicians can determine which option is best for your situation. 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 2020 Mercedes-Benz GLS450 tire puncture can be repaired, we'll follow three basic steps to repair it: (1) Remove the tire from the wheel for inspection and repair, (2) fill the puncture to keep the moisture out, and (3) secure and seal the inner tire liner to ensure the tire is airtight.

Mercedes-Benz GLS450 Tire Replacement

Sometimes, 2020 Mercedes-Benz GLS450 tire damage calls for more than a repair. Tires with less than 2/32nd inch tread remaining can't be repaired, no matter how minor the damage. This tread depth indicates that the tire is worn out, and needs to be replaced. Some tire issues are easy and straightforward to repair, but other kinds of tire damage can’t be properly repaired. Tire damage that can’t be repaired effectively include a puncture in the tire that is ¼ inch or greater in diameter; a tire with a puncture or damage outside the tread area; multiple punctures that are too close together (less than 16 inches between them); and a tire with cuts or tread separation.

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. But, if you’ve recently replaced your tires and they don’t have significant wear, a new set might not be needed. 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.

Do I Need a Tire Inspection for My Mercedes-Benz GLS450?

A flat tire is a surefire sign of tire damage, but other indicators of tire issues aren’t so easy to spot. Inconspicuous issues like bulging sidewalls, exhaust noise, leaks, or bent rims may indicate issues that need immediate attention. Stop tire damage in its tracks. Start with a tire inspection on your 2020 Mercedes-Benz GLS450.
