I bought these tires for a 2007 Honda S2000 as a replacement for the stock Bridgestone Potenza RE-050 non Run-flat. These had worn down to wear indicators by 45K miles and the road noise was now being fully transferred through the chassis and into the cabin where it had become unbearably loud.
I was looking for a bit more width and I happened upon these. The stock rubber had a tread width around 9" and these 255s reigned in at 10.2" with minimal tire bulge (if any). Ding!Ding!
During the break in period I observed posted speed limits and kept my speeds around corners >/= 20 MPH over, which is not even working this car's suspension. I felt as thought the sidewall was flexing in an exaggerated manner; the rear of the car felt like it was wiggling upon any sort of steering input and it felt very unsettling around corners. I felt as thought I made a huge error.
Then right around 300 miles, the tires must have settled in all of these conditions are gone and the car has never felt more stable, responsive, or planted. I will continue buying these tires for the rear of the car, provided they wear decently. Now the fronts…
While I was tempted to take advantage of this series of tires' wide contact patch/squared shoulders for the front, I am thinking I need to stick with 215s instead of bumping it up to 225s. Stock Re-050s are only about 6.6" in width, probably contributing greatly to the car's uber-responsive turn-in. These G-force 2's have almost 8.5" of tread width on the 215s that's crazy wide. These ain't no pizza cutters! The last thing I want to do is numb this car's steering or add too much in the way of unsprung mass.
