I had a fight with a curb a couple of weeks ago. I need a front and rear wheel. I will either buy new or maybe find a used set of 4, if it is cost effective. My question is how do you measure backspacing on the wheels. I bought these used and alway's assumed they had 5.5 backspacing but i'm not sure. Any pics would be great also. The wheels in question are the prostars in my sig.

 

Someone has to know. Anybody??????

 

this link explains how and also has a pic...

 

Thanks alot 88.
