Thats true. A 10.5 tire is not all that wide for a car that has been tubbed. I would first do the measuring of what you got then buy wheels that fit. No reason to have the tires sticking out if you have that much wheel well to work with. If you keep the tire inside the lip you will have some extra room to work with and a 28 will fit with out having to cut any thing. Time to get out the tape.
