Sorry if this is old news, but I just looked closely at the E92 M3 specs in the German press release, and discovered the rear tires are larger in diameter than the fronts.
Tyres, front/rear 245/40 ZR18 / 265/40 ZR18
Rims, front/rear 8.5J x 18 EH2+ IS 29 aluminium, forged/9.5J x 18 EH2+ IS 23 aluminium, forged
According to my calculations, since the aspect ratio is same front and rear, the rears are .40 x 20 mm x 2 = 16 mm ( 5/8") larger in diameter. This is confirmed by Michelin specs which show .60" difference (809 vs. 790 rpm) Anyone else notice this?
