I have seen some issues with tires - AKA Continentals on the 2005 300c's . I have been to the dealer twice , once for irregular tire wear (dealer replaced and re-aligned) and again for the same issue . This time the dealer replaced the wheels(curosion on the machine lip - all 4)and said I would have to chase Conti for new tires ...
So , I took it upon myself to find a new tire and get the car "professionally" aligned since I at least had 4 new wheels also . I bought some BFG KDWS that are the same diameter but a half inch wider (looks good) size escapes me at the moment ... 245-55 R18s , I think . Anyhow , it seemd to have gotten the car to ride and drive slightly better but now I have a shudder in the wheel at about 75 plus
Anyone out there with some of the simalar issues ?? recommendations??
Still the smoothest looking car on the road !!
