is it posible to run 15" rims on a 98 gmc 1500 or does it have to be 16" rims
I think it might have to be 16" rims cos of the calipers, I think!!

on a d60 you have to grind the calipers to fit 15's im not sure about the 1500s

I put 15 inch on a 94 gmc 1500 4x4 no problem

Depends on the wheel. Many 15's do not fit. Going with less backspacing than stock (5") will help too.

so I guess what I need to know is how little of backspacing can I get away with. Any more info would be great and thanks for all your help.

scroll down and you'll see my post with pics, I'm not sure about the back-spacing is on these rims though

nice looking truck. The backspacing looks large. I wonder what the min. backspacing would be.

There can't be a minimum backspacing. I would say 2-3" max backspacing with 15s... unless you can find some thinwall 15s that are virtually cylindrical. ;)
