Plus-one sizing
 
Help!
Does anyone know the "plus-one" sizing for stock M3? the original tires are 255/40-18 on rear and 225/45-18 on front. Besides "plus-one", which I THINK is 275/35-18 for the rear...does anyone know if the 255/35-18's from the 330sport package will fit the rear of the M3?
Any help would be greatly appreciated.
Thanks

Although we technically call this 'plus zero' (plus one goes up one wheel diameter size to 19") you have the right idea. For wider tires on the stock M3 18" wheels you can use 245/40R18 up front and 275/35R18 on the rear. 255/35R18 is pretty short in height for the M3 and not recommended.

How much "taller" will the new sizes look? Very noticable, or just a little. the reason is that I want to go to Pirelli P-Zero Nero, and they are not available in the stock sizes.
thanks!

The new sizes won't be any taller, in fact they're about .3" shorter, but about an inch wider both front and rear.
