I have to write this review to talk about these tires. First the Goodyear F1 RFT came stock. They were great in the rain, good dry traction especially on the 1/4 mile track, hooked and leapt off the line, however the ride was horrible. One think I really did like about the Goodyears, they have a protective lip that covers the rims, protects them from curbs. The turn in was terrible. The Goodyears lasted 14,000 miles. The insides wore past the wear bars, on factory alignment.
Now on to the Michelins, unbelievable difference in ride quality and road noise over the Goodyears. These are non-runflats so the side walls actually give. Better ride more compliant over bumps, so far no tramming (live in the D.C. area 495 on and off a lot). The best part is the turn in these tires are so willing to turn and give you so much more confidence than the Goodyears. I cant believe the grip they have, the harder you throw them into a corner the better the grip. Have not got them to squeal yet. That will happen next week at the track. Will update next week after the track. They look a lot more aggressive on my rims as well.
