I just purchased wheels at Tire Rack (Kazera KZ-K BLK MA LP wiYokohama ADVAN S.4. ) 18x7.5 50mm 225/40/18 front 18x8.5 55mm 255/35/18 rear. wondering if will be ok.

 

Easy fit. Enjoy em!

 

Thanks. was just concerned about the 255s on the thanks for the help.

 

fronts will fit with no issues.
rears with +55 you might need UK camber specs. ( -2 )

I run SSRs with +55 offset and 255 RE01R and got small rubbing on heavy bumps but my rear camber is around -1.3..-1.5

Just realign to UK specs (do search for exact numbers) after wheels installation and I think you are good.
