I have ordered a strut brace and set of CSL alloys for my Z4MC - what size rear tyres should I fit 265 or 275/30? Any comments on the best tyre make/model? The car will be mainly used on the road.
For the CSL wheels you can either go for 235/35/19 front and 265/30/19 rear or 245/35/19 front and 275/30/19 rear, both sets of sizes fit fine. Michelin PS2s seem to be the way foward on the Z4MC.
