E430 Tire problems
I don't know if its a Tire Construction issue, if its an Alignment issue, or possibly even an uninformed Customer issue
Recently there seems to have been an increse in problems with the 430's running 235/45 17's. Most of the tire issues have been with either the Pirelli P7000 and the Goodyear Eagle F1.
Either the tires wear unevenly, become very loud after time, or get road damage.
I have also seen an increase in many damaged and bent wheels from these cars also.
I have a 2002 E430 4Matic that came with Pirelli P7000 235/45ZR17 tires. I knew from previous experience that Pirelli's would be noisy, but I didn't expect tire failures. 15 months, and about 25,000 miles after delivery, I hit a pothole and lost the right front tire (and rim). 3 weeks later, left front tire blows out through sidewall at 75 MPH (car handled well, but changing tire at night on interstate in middle of nowhere with trucks passing by 3 feet away is not my idea of fun)! A month or so later, I noticed a slow leak in the left rear tire (about 10 PSI per week). I put up with that for a couple months until yesterday I found a bubble in the sidewall on the (6 month old) left front tire. By this time (33,000 miles), the tires were singing louder than the stereo, and so I threw in the towel, and threw out the Pirelli's. I've now put on a set of Toyo FZ4's (same size) that seem much quieter (but I've only had them one day). Anyone have similar experiences? When I asked the dealer about the tire failures, he said that MB should never put this low profile tire on cars sold in the northeast US. So I asked him for another tire/wheel combo, and he said there weren't any! So, the options seem to be to be prepared to buy a lot of tires, or sell my car!
I would never run tires over 33.000 miles on a high performance car like E430 4matic.
My optinon is, that tires are the life insurance for you, in a anyhow dangerous driving environment. Considering the cost of a set of new tires after a reasonable milage (say 20-25kmls) is well worth it, compared with the loss of health or life for you, your familiy and maybe others drawn into an accident, because of a tire failure.

Sincos, the 1998 and 1999 E430's had 215/55R16 tires, with 235/45R17's for the Sport Package. You might want to check with your dealer and see if they'll work. I drove a 1999 and found it FAR preferable.
