After a long and somewhat bumpy road since importing my car earlier this year I can see the light at the end of the tunnel and the car comes back from full paint job this weekend. One of the jobs that's left to do is get the polished lips on the genuine bbs rims re-cut and fit four new tyres. So my rears are 18x10 et50 and came with 245/40 rubber which looks stretched and won't pass test here, fronts are 18x9 et42 and have 225/40 fitted which also look stretched. What can I fit without rubbing? Can I go 265 or 275 rear and 235 or 245 front?
