How soon should I have my flat tire repaired?

Driving on a flat tire is not a good idea. Your 350SDL engine will keep running with a flat tire, but you could damage your wheel by continuing to drive on a flat.

Is temporary sealant bad for my Mercedes-Benz's tires?

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?

Don't rely on your spare tire for too long. Your 1990 Mercedes-Benz 350SDL 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 350SDL tires?

In most cases, your nearby Firestone Complete Auto Care can handle your Mercedes-Benz 350SDL tire repair. Ultimately, the severity of the damage will determine if your tires can be repaired.

Why do my 350SDL tires keep losing air?

Your 350SDL tires might keep losing air due to a leaking valve stem, puncture or hole in the tire tread or sidewall, or damaged wheel.

Is it necessary to replace all four Mercedes-Benz 350SDL tires at once?

While it may not always be necessary to replace all four tires on your 350SDL, 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.

Mercedes-Benz 350SDL Tire Repair

Urban areas are booming. Roads are expanding. There's construction around every corner! That means more tire-damaging road debris and flat tires. If the road has been rough on your 1990 Mercedes-Benz 350SDL 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 1990 Mercedes-Benz 350SDL tire can be safely repaired, we’ll get to work on the steps to fix it: (1) Take the tire off the wheel for easy inspection, (2) use a filler to close up the puncture (this is to keep moisture from getting in), and (3) seal the inner liner with a repair unit to prevent air loss.

Mercedes-Benz 350SDL Tire Replacement

Not all 1990 Mercedes-Benz 350SDL tire damage can be repaired. 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. Other tire damage that can't be safely repaired includes a tire puncture with a diameter bigger than ¼ inch; a puncture that lies outside the tire tread area; multiple punctures that are too close together (less than 16 inches between them); 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. 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 350SDL 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 1990 Mercedes-Benz 350SDL in for a tire inspection so we can assess the damage and help keep you safe on the road.
