hi, all new guy here I'm doing g a frame up restoration on my 78 Silverado. I'm running 245/40/20 and 275/40/20 was wondering if 245/45/20 and 275/45/20 would give me a better ride. or no significant difference I have slozh tubs so tire room isn't an issue. I just installed Qa1 front crossmember and coil overs and 4link rear with coil overs.
