Another tire size info
I don't know if that will fit or not. Mines a 71, so there may be differences.
I've got some 27*9*15 and have rolled the fenderlips, car is 1.5" over stock height in the rear and its real tight. I've got monoleafs which helps a little and the passenger side still rubs from time to time.
I can't remember whether my wheels are 4.5 or 5.5, but I'm using spacers and still have problems on the leaf side.
The M/T 28*9 doesn't measure out a whole lot bigger than the QTP I'm using as far as sidewall width, but its really tight.
