Actually, you can measure the circumferance (sp) of the tires you have and then the new tires. Then adjust the suspension (raise or lower) to make up the difference and the handling will be very close to the same. However, different profile of tire will change things. Example: Go from a BT 010 to a 208GP. Huge difference.
Forgive & forget. Just never forget when I forgive.
in that new tire test in SR i mentioned yesterday, they said, "those new sportecs, at the track, snagged some HIGHER ratings than even the rennsports"...!!! and to top it off, they "showed ALMOST NO DISCERNIBLE WEAR after a 150 mile test"...!?!?! they even closed by saying, "the M1's had ABOVE AVERAGE wear after their 30 min test session"...!!!
needless to say... after first learning their postion in the metzler line up... i'm left STUNNED by how well they've performed...
