2010 WRX-S Alloy Wheel Size
 

Anybody help? Can't see any markings exept ProDirve.
Tyres are 225/40 R18

Need another set for my summer tyres...........
Rang a few scooby places but they keep telling me they are 17" and don't seem to understand that the 'S' model is upgraded to 18" as standard.

All information if possible please :brickwall

Have a look at the Subaru website for the official options and additional equipment, surely there will be some downloadable brochures, but I would have thought that you'd have 8x18" ET55 rims with those tyres.
