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

Driving on a flat or underinflated tire can put extra stress on your wheels and alignment. While it’s sometimes necessary to drive a short distance on a flat tire to get to a safe place, don’t take any other trips in your SL450 until you can have the flat tire repaired or replaced.

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.

What’s the harm in using my spare tire 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 2020 Mercedes-Benz SL450 is intended for only a few days of use, so don’t use it as a substitute for getting your tire repaired.

Who can repair Mercedes-Benz SL450 tires?

Your local Firestone Complete Auto Care can carry out most Mercedes-Benz SL450 tire repairs, but the extent of the damage will determine if we are able to help.

What can cause SL450 tires to keep losing air?

Your SL450 tires might keep losing air due to a leaking valve stem, puncture or hole in the tire tread or sidewall, or damaged wheel.

Do I have to replace all four Mercedes-Benz SL450 tires at the same time?

It's important to consider replacing your SL450 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 SL450 Tire

City populations are exploding. New roads and buildings are springing up. Everywhere you look, it seems construction is in progress! Unfortunately, this can mean a higher chance of a flat or damaged tire caused by debris in the road. If the road has been rough on your 2020 Mercedes-Benz SL450 tires, Firestone Complete Auto Care can help. 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. 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 we determine that your 2020 Mercedes-Benz SL450 tire can be safely repaired, the repair process is actually fairly simple: (1) Separate the tire from the vehicle wheel, (2) fill in the area that’s been punctured to prevent damage from moisture, and (3) re-seal the inside lining of your tire so that air won’t escape.

Mercedes-Benz SL450 Tire Replacement

Sometimes, 2020 Mercedes-Benz SL450 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. At this tread depth, the tire is worn out and must 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 tire with a puncture larger than ¼ inch 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 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 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. 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.

Mercedes-Benz SL450 Tire Inspection

Some tire issues can cause you to have a flat, but other damage isn't so noticeable right away. Inconspicuous issues like bulging sidewalls, exhaust noise, leaks, or bent rims may indicate issues that need immediate attention. Bring your 2020 Mercedes-Benz SL450 in for a tire inspection so we can assess the damage and help keep you safe on the road.
