Thank you for your imput. I too believe that since the Pantera was designed around the 225/50-15 and 285/50-15 tires and the 8" and 10" Campy wheels that the look and stance was just right for the car.
I do like your suggestoin for the 17" rims w/235/40-17s and 335/35-17s and it seems that several vendors offer this combo. It's too bad that 15" tires are so difficult to find in the sizes that we need. Thanks again!
Garvino-I was afraid that the 17s would push the rear upwards as you suggested. My car has had the spacers knocked out of the stock shocks long ago and I really like the handling and stance w/them gone. I guess unless I want to scour the earth and spend ungodly amounts of money to purchase some 15" tires again, I'll have to make due with what's available to us! BTW where in Wyoming are you from? I'm up in Cody.
