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

Driving on a flat tire is not a good idea. Your S420 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?

Fast fixes are a mixed blessing. They’ll help you get your Mercedes-Benz S420 to Firestone Complete Auto Care, but don’t count on them to keep you on the road for very long. Using a temporary sealant may also void a Bridgestone or Firestone tire warranty.

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 1994 Mercedes-Benz S420 is intended for only a few days of use, so don’t use it as a substitute for getting your tire repaired.

Who repairs Mercedes-Benz S420 tires?

In most cases, your nearby Firestone Complete Auto Care can handle your Mercedes-Benz S420 tire repair. Ultimately, the severity of the damage will determine if your tires can be repaired.

Why do my S420 tires keep losing air?

Tire punctures, damaged wheels, and leaking valve stems are possible reasons for your S420 tires continuously losing air.

Can I replace just one or two tires on my Mercedes-Benz S420?

While it may not always be necessary to replace all four tires on your S420, 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.

Get Your Mercedes-Benz S420 Tire Repaired

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 1994 Mercedes-Benz S420 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 start by evaluating the state of wear, the location of damage, type of damage, and the size of the damage.

If your 1994 Mercedes-Benz S420 tire puncture can be repaired, we’ll get to work on the steps to fix it: (1) Separate the tire from the vehicle wheel, (2) use a filler to close up the puncture (this is to keep moisture from getting in), and (3) secure and seal the inner tire liner to ensure the tire is airtight.

When Is It Time for Mercedes-Benz S420 Tire Replacement?

Not all 1994 Mercedes-Benz S420 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. 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. Manufacturers of AWD vehicles, for example, often recommend replacing all four tires at once because AWD systems need uniform tires to operate properly. 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. 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.

Tire Inspection Services for Your Mercedes-Benz S420

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 1994 Mercedes-Benz S420 in for a tire inspection so we can assess the damage and help keep you safe on the road.
