I have 15x8" rims w/ 4.5" of BS and a 295-65 drag radial...very close to a 29.5x10.5 slick. I also have another pair of rims that are 15x8.5" w/ 5" of BS that have 29.5x10.5 slicks on them. Both sets fit the '69 RR w/ factory 1/4 panels, but neither will fit the '69 RR that had new 1/4s put on. They hit at the top outside edge and the front edge. The body shop that installed the 1/4 panels neglected to trim them back like the factory ones. Didn't notice it until after the paint work was all done.  A 28x10.5" or 275-60 fits great on it though.
