Help with Wheel and tire combo please!

Everything is dependant on your specific car. You can look to others for guidance or similarities; however, odds are no one will have the exact same setup as you. IMO, the best thing to do is to look at other cars that are similar (so in your case it could be 72bluNblu's Duster). But depending on what rear end, springs, UCA's, brakes, etc. you run can change your wheel options dramatically. I say, measure 10x's, order once.

It would help if you gave us a little more information like what bolt pattern you have, how wide your 8 1/4 is drum-to-drum, what brakes your running, etc. Also define a decently meaty tire... Width? Height? How tall or wide? Some people don't like the short sidewall look or feel.
