im looking to upgrade my rear tires. ive seen some threads on guys using on their duallies up to like 295s or something with 2 inch spacers on them. i have some 265 75's from a friend i would like to put on and im thinking i will need some longer studs, since i will assume i will need some sort of spacers back there. has anyone any ideas on what i need or where to get them. or am i gonna just have to get down and dirty and take it apart and do a little hit or miss on it?
