73 Duster help .

Thats really funny that 3 or 4 differant vehicles can run 3 or 4 differant sizes and do or donot work...it must have something to do with where the k frame sets in your front end and the strut rods ..thats all i can figure.one other thing,is on my wifes vehicle we put on 265 70 of one brand and had 2 tires 265 70 of another brand and one brand was almost an inch narrower than the other..and on the duster,the driver side is a little tighter than the pass side,.car looks good tho.My sons happy with it...tx..j
