Does anyone know what the bolt pattern is on a 1990 Chevrolet c1500 5 bolt?

I don't know if it is a 5" of 4.75"

ALso what is the correct offset?

I like my wheels to stick out just a little, not really an offroad look more like a sport truck look

THanks for the information

 

I don't know anything about the offset, but I do know your bolt pattern is 5" X 5"

 

Thanks, actually I meant setback.

I am buying some rims on ebay that have a 4.5" setback, I just don't want them to be too wide to fit on my truck.

 

Backspacing is the term I think you're looking for. Setback MAY be another term, but I've never heard of it.

4.5 is a backspacing used for offroading rims.

 

Thanks
