Can I drive my Mercedes-Benz on a flat tire?

Driving on a flat tire is not a good idea. Your 420SEL 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 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?

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 1991 Mercedes-Benz 420SEL is intended for only a few days of use, so don’t use it as a substitute for getting your tire repaired.

Where can I get my Mercedes-Benz 420SEL tires repaired?

In most cases, your nearby Firestone Complete Auto Care can handle your Mercedes-Benz 420SEL tire repair. Ultimately, the severity of the damage will determine if your tires can be repaired.

What is causing the tires on my 420SEL to keep losing air?

Possible reasons for your 420SEL 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 Mercedes-Benz 420SEL?

While it may not always be necessary to replace all four tires on your 420SEL, 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 420SEL Tire

Cities are growing. New roads and buildings are springing up. There's construction around every corner! New progress is exciting, but the road debris it leaves behind may mean trouble for your tires. If the road has been rough on your 1991 Mercedes-Benz 420SEL tires, Firestone Complete Auto Care can help. 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. 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 1991 Mercedes-Benz 420SEL tire is feasible and safe, we'll follow three basic steps to repair it: (1) Separate the tire from the vehicle wheel, (2) fill in the area that’s been punctured to prevent damage from moisture, and (3) secure and seal the inner tire liner to ensure the tire is airtight.

When Is It Time for Mercedes-Benz 420SEL Tire Replacement?

Not all 1991 Mercedes-Benz 420SEL tire damage can be repaired. 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. If your tire is not yet worn down, there are other forms of damage that simply can’t be repaired, like a tire puncture with a diameter bigger than ¼ inch; a tire with a puncture or damage outside the tread area; a tire with multiple punctures that are less than 16 inches apart; and a tire with tread separation or significant cuts.

Depending on what Mercedes-Benz recommends for your car, you’ll want to consider purchasing one new tire, two new tires, or a new full set. 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. If you can replace your damaged tire with the same type, brand, and size as the others, you may be able to save costs and only purchase one replacement. Need help? A tire technician can walk you through the options and help you determine what’s best for your vehicle’s performance and longevity.

Mercedes-Benz 420SEL Tire Inspection

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. Stay ahead of potentially dangerous tire issues. Bring your 1991 Mercedes-Benz 420SEL in for a tire inspection.
