Hi all. I just upgraded my 15 inch stock wheels to 17 inch Mille II wheels and Falken tires. The wheels are used but look to be in great shape while the tires are brand new. At 50 mph the car starts to shake...at about 60 mph the shaking smooths out... The tire dealer reset my frontend camber and has done everything possible...mutiple balancing, rotated the tires on the wheel and has indicated that he will replace the tires if need be. The dealer is a great guy and I would like to spare him the hassle of going to new tires. Any suggestions? I was also wondering if the tread pattern was at fault. I had no problem with the stock wheels and tires. Thanx
