It's all going to depend on the offsets,..suggest you read the wheel fitment sticky at the top of this forum before you buy. 9"to10" wide with a 275 tire you'll want a +60mm offset to avoid rolling fenders or running excessive -camber.

 

10 inch wide with a 275 tire you actually want a +73 offset, on a 9 +58 or as low as +55 but that all depends on tire size. as captain mike said, read the wheel fitment guide
