quick question.short answer plz

I suppose those rims have a 4" bolt-circle, and are for the stock rearend.?
I'm pretty sure yes you can bolt those on. But
I'm also pretty sure there will not be any sidewall room for the 245s that are the right size for those rims. Well, you might get them in there, but you might not be able to drive in a circle.
But cheer up, you can install spacers that come in .25" thicknesses. You just gotta make sure you have enough wheelstud left to hold the daymn nuts on.
