tires and rims

[weed9340]

hello everyone have a 71 duster 340 std, looking for ideas on rear tires, right now I have 245/60/14 on Chrysler silver rally rims 8" wide and 4.625" backspace. would like a wider tire in 14" but very hard to find. My next option would be 15" has anyone had any experience what works to fill that rear fender with tire and rims that don't rub. Also I have air shocks on rear. Thx

Out of luck in a 14" unless you go with a 26x10.00-14 drag tire. 275/60r15 is as wide as you can go without moving springs
