Time to Buy Tires for the Duster......help please.

Dave, those 275's fill the rear fender nicely. Are you running a stock suspension? I wonder if they will fit a 7 inch rim? You have some awesome rides. I am so lusting after your m code 'Cuda. A m code coupe would be my ultimate dream car.
Thanks but I did sell the M code. Yes stock suspension with a small lower blocks. 4 1/4 backing space should fit. I know 4 1/2 does not(to close to the spring). Do you have anybody you know that you can try tires?
