just to give you an idea... a 245 is 9.65" wide a 255 is 10.04" a 255=10.43". Generally you can go 1.5" safely using any rim and any tire for any car. After that it gets sketchy. It does matter what series tire you want to use. You could probably mount a 285/75r15 on a 8" rim( not that you'd want to) but you couldn't mount a 255/25r15 on a 7" rim, get my point. Are the 10 holes 7" wide? or 8"?
Tub it!!
