87 GN, 4 Front GTA rims, no spacers. I have 245s on there now and I can get my hand between the tire and frame in the rear - how close in the fit with the 255s?
a 255 is 10mm wider- a centimeter, or just under 1/2".. so it will be just under 1/4" closer to the frame.
I'm running 255 / 50 x 16"s on the rear on Front Offset GTA rims and just like most of us = no problem. However, I understand that if your axle is not centred if could be an issue? "Just sayin" dave
