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 E420 until you can have the flat tire repaired or replaced.

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?

Don't rely on your spare tire for too long. Your 1994 Mercedes-Benz E420 may come equipped with a compact spare tire. A spare is different than an everyday tire and is only designed to be driven a certain number of miles at lower speeds.

Who repairs Mercedes-Benz E420 tires?

Your local Firestone Complete Auto Care can generally take care of most Mercedes-Benz E420 tire repairs. However, it depends on the severity of the damage.

Why do my E420 tires keep losing air?

Your E420 tires might keep losing air due to a leaking valve stem, puncture or hole in the tire tread or sidewall, or damaged wheel.

Do all four tires on a Mercedes-Benz E420 have to be replaced at the same time?

It's important to consider replacing your E420 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”.

Mercedes-Benz E420 Tire Repair

City populations are exploding. New roads are being built, and old ones are getting a face lift. There's construction around every corner! Unfortunately, this can mean a higher chance of a flat or damaged tire caused by debris in the road. If your 1994 Mercedes-Benz E420 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 1994 Mercedes-Benz E420 tire puncture can be repaired, we'll follow three basic steps to repair it: (1) Separate the tire from the vehicle wheel, (2) fill the puncture to keep the moisture out, and (3) seal the inner liner with a repair unit to prevent air loss.

Tire Replacement for Your Mercedes-Benz E420

Not all 1994 Mercedes-Benz E420 tire damage can be repaired. For tires that have less than 2/32nd inch of tread left, a repair simply isn’t possible – even if the tire damage is minimal. Tires with this tread depth or less are no longer safe, so it’s time to replace the damaged tire. 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 puncture with a diameter bigger than ¼ inch; a puncture in the tire sidewall (or anywhere else that’s not within the tread area); a tire with two or more punctures that are less than 16 inches away from each other; 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. 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.

Do I Need a Tire Inspection for My Mercedes-Benz E420?

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 1994 Mercedes-Benz E420 in for a tire inspection so we can assess the damage and help keep you safe on the road.
