Symptoms:

I have this 95 Mercedes Benz S320 that has tires wearing quickly on both edges of the right tires after it gets about 5000-10,000 miles. A recent front-end alignment was performed and both the alignments at the front and rear were found OK. All front end components including the link bushings were within tolerable limits, shocks were responding properly and no visible indications that any parts are worn. Thanks in advance for your help.

Tire Problem Advisor:

Since this car suspension has no car levelling system, this problem will be a little bit harder to diagnose. For this type of tire wear, checking the rear lower control arm bushing is the best option. Check for looseness by prying it and verify for any movements. If found defective, take this car to an authorized MB shop to replace the bushings for you.

However, most of this problem can be attributed to poor monitoring of tire pressure, which must be kept at the recommended rates (see your car manual for proper setting). Finally, you should try using Michelin MXV4 tires for this type of car. Findings show that this type of tires gives at least 30,000 miles life on the treads of course depending how you drive the car and maintain the tires.

Notes:

When servicing the front-end of this car, take note that the ball joints are maintenance free and require no greasing. If there is any visible looseness, replace the ball joints.

When in doubt, bring your vehicle to authorized Mercedes Benz dealer shop for a second opinion to avoid repetition of the tire problem.
