hi all .. quick question ..

will there be any problems with running 195's at the front and 205's on the rear .. while running on 15"s ???

I need to get the rear tyres replaced ASAP and as i've got some spare rubber from an old set of 15's, only 2 of them decent, thought that I could use them on the rears. Im getting some 17's in a few months so I don’t want to spend money unnecessarily.

cheers, Lee
