How do i measure rim width

[sage2k]

I have some cobra rims I bought off someone last year and I wanted to measure the rim width, I measured from lip to lip and got something like 11 inches which i know is way wrong, it has to be either 8 or 9 inch I think, but how do i accurately measure what it is?

its probably a 10.5" rim. thats what mine measured out to be on my 10.5's. and when I measured my 8" ones they came out to 8.5".

theres no way its 10.5 cuz all 4 rims are same size and im using 235/45 tires and am wanting to take off these crappy tires.

Measure lip to lip and subtract 1" and that's the actual wheel size. My Cobra wheels and 9"s lip to lip but are 17x8s.

I agree with black vert!
