I had new Michelin PS4S put on the 458 today and my driver side rim needed nearly 8oz to balance. The tire tech showed me the rim spinning and you could see the rim was out of round. Is this fixable or should I purchase a new rim from ebay. The tires I took off were original Pirelli tires that came with the car but were cracking and showing dry rot and dated 2012. If you think it is fixable are there any suggestions for orange county ca rim repair.
