I have no experience with F1's, but this is the 4th season on T1R's on my MINI, and the treadwear appears to be fine, and evenly wearing at all corners. Oddly enough, for a front drive car, the MINI is hard on rear tires. I rotate seasonly and they are holding up very well.
I will not hesitate to put T1R's on the E90 once the RE050's wear out. (Can't come soon enough)
