Thanks but I don’t think a 13 will fit over my aftermarket disc brakes.
I bought a $5 one at the junkyard off a small dodge compact. It was metric & the bolt pattern was close, but not close enough.
I also have sure grip, so that is an issue too. Right now I have a 215 14 & it is about 2-3 inches too wide for the trunk floor to be level. Oh well, I don’t really use the trunk much anyway.
