That I need to figure out which I don't know how. Am I better off taking it to a tire shop?
Are your wheels and tires new? The reason I ask is because if the backspacing on your wheels if off you're going to need to buy new ones. Not that that's bad if you have the dough but some don't have it in the budget.

They are a couple years old. A lot of tread.

take the tire off.....turn it over...take a straght edge(small 2" level or similar tool)put it across the lip of the rim(not the tire)measure from the wheel hub mounting surface up to the straight edge...this will give you your wheel bs

Some what.. Back spacing numbers and wheel width numbers dont always account for the "extra" 1/2" (each side) of the wheel, the lip.

For example a 10" wheel is physically 11" wide, lip to lip. And that usually doesnt matter to most folks unless you are doing a critical wheel fitment, like trying to stuff the largest wheel you can into the space you have.

Then the actual wheel width is needed to find out what will fit. The B.S. calculation that BM gave you works for backspacing. But you might need to add the 1/2" on the inboard and outboard sides if you plan on using some wheels that are very close to the frame or other hard parts.

Backspacing measurements from tire and wheel dealers dont usually take into account for the extra 1" (1/2" on each side) of lip.

They will advertize a certain backspace for a wheel on the advertized wheel size which is diff than the actual size of the wheel. Lemme say, it can be a cause for disappointment when the great new wheels arrive. Its better to make sure and talk with the dealer before buying.

An advertized wheel size WONT be the actual size of the wheel, it WILL be larger by about one inch. Just something to think about when buying wheels. JR
