stu,

thanks for the detailed explanation that really helped me understand, One of my rims from the front that i have unmounted is a 3.75

and the other one that is still mounted has a 6.0 tire on it, but it still does have a different style ring

The guy with the full set of rims is supposed to call me tonight so hopefully i can nail down what he has, if they are wider i might just have to settle for them...

Thanks again for all your help
