thanks , edited.
1% seems very low. Front wheels diameter VS rear wheel diameter should be in the 1% margin?
People who doing track, will have more than this because of tire wear.
anyway, I wont take any chances, and put some same size tire. I was thinking about 285 at the rear, but it got 1% VS the 245. Ill get some 275 instead.
3% of the OEM diameter for ''speedometer'' is as per owner choice at the end, you can go 8% if you want, it wont break anything. I you are aware that the 60 is the new 65 i.e..
Braking distance VS diameter should be negligible in those 3% margin. width and tire quality is way more important.
