In my quest to find a RCZ to potentially be a donor for parts , I stumbled across a 1.6 GT 200 wearing 255 40 r 19s on standard RCZ wheels as opposed to 235 40 r 19s fitted to my 1.6 GT 156. Is the 255 tyre suitable for the RCZ, looks like its been running on them ok. There dont appear to be any spacers or any other change in play. Anyone else running on 255s?
