I think 235 is the widest u can fit with out any mods on the back..for the front maybe 225. I have a pair of centerline American racing rims with decent tiresome sale but I'm located near LA California.. Tire size on those are 235 60 r15. They were on my 67 valiant when I bought it but they would rub on the inside of the wheel well . I have stock shocks maybe some hi jacker shocks could of helped ... But I like the stock look so I switched them out for the cool steelies
