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

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 S420 as little as possible to reduce your risk of damage to the wheels and alignment – or further damage to that already struggling tire!

Will a temporary sealant 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.

How long can I drive my Mercedes-Benz on a spare tire?

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 1999 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.

Where can I get my Mercedes-Benz S420 tires repaired?

Your local Firestone Complete Auto Care can generally take care of most Mercedes-Benz S420 tire repairs. However, it depends on the severity of the damage.

What can cause S420 tires to keep losing air?

Possible reasons for your S420 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 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

Cities are growing. New roads and buildings are springing up. There's construction around every corner! That means more tire-damaging road debris and flat tires. If your 1999 Mercedes-Benz S420 is in need of a tire inspection or possible flat tire repair, Firestone Complete Auto Care has your back. 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 1999 Mercedes-Benz S420 tire puncture can be repaired, we'll follow three basic steps to repair it: (1) Take the tire off the wheel for easy inspection, (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.

Tire Replacement for Your Mercedes-Benz S420

Sometimes, 1999 Mercedes-Benz S420 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 puncture in the tire that is ¼ inch or greater in diameter; a puncture in the tire sidewall (or anywhere else that’s not within the tread area); multiple punctures that are too close together (less than 16 inches between them); and a tire with cuts or tread separation.

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 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. It’s possible that you will only need to replace the tire that’s damaged – just make sure it’s the same size, type, and brand as the rest of your tires. 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 S420 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 1999 Mercedes-Benz S420 in for a tire inspection.
