Beware of Extremes if you care
I replaced my PS2's with Conti Extremes two weeks ago and they cannot balance them or at least their machine says they are balanced but the car says they are not(March 11 and again March 14, 2011) . I am using a well known performance shop who have mounted and dismounted tires for me for a decade or so. The PS2's were great but worn in the rear as usual. No balance issues for the 2 3/4 years they were on the car. E60 M5.
I am in a conversation with Tire Rack where I bought them to replace them under the 60day free trial. Wheels are stock and near perfect. They are willing to pay me less than half to mount and balance them than I paid and did not offer to pay the freight both ways, return and delivery of new tires, I'll go back to PS2's. If I kept these Contis as they are I could not have any confidence in them and would hate the car.
The un-balance problem gets worse when coming off the highway and driving slower to 55 or so. I think the tires are not constructed like the
PS2's and yet Tire Rack users give them the highest marks and they provide a video testing them and PS2's and something else. When hot they loose shape or something. Also I would add that they may not be matching the front and rears properly as the wheels and tires are different sizes.
Anyone seen this.
