Kevinski - If the "blazer ralleye" rims are 15" diameter, you will likely experience interference with your tie rod ends with the extra width of the 8" wide wheel. Either tire or rim will most likely have contact with the tie rod ends without modification or spacing the rims out away from the hub face.

I seem to recall someone went through this and had the interference problem. It's possible the "disc brake" ralleye wheels had more clearance, but I couldn't find the threads that talked about those things.

Maybe someone else knows???
