Quick question got a set of tsw evo-rs for my saff going to order tyres as there is 205 40s on them and look a bit skinny. whats the best size? its rwd on bilsteins. cheers

 

probably a 7" rim so go for a 215/40...........

 

Hi Steve,

I asked a similar question a while back - it seems to depend on the tyre make and whether you want to mod the arches at the front.

The gist seemed to be 205/40s if you don't want problems with the arches....unless the 215 is a 'narrow' brand

 

Ive got standard suspension on my cossie and i have 215/40/17s on my wheels and the drivers side front seems to catch on the arch every now and then.
