After replacing 225 40 18 front and 255 35 18 rear Federal RSR semi slick on my BMW Z3M Coupe S54, I put different wheels front-rear, 235 35 19 front, 255 30 20 rear. I put those wheels just to have it for better car looking. First problem was to balance rear tyres. I put on and off tyre from wheel 2-4 times to get even a chance of balancing it. I can see from my eyes that brand new tyre is not straight, it was deformed. But, when I manage to balance it, I could say i'm ok with this tyre.
I do not expect anything, but tyres was ok in feedback, progressiveness, even wear is much better than previous ones.
Generally, I like construction of federal tyres, they have very strong side walls (almost like run-flats) and that gives very good feedback.
