drs66 has a set of 22 inch rockstars that he had to have custom drilled. You might check to see if they even make the rockstars to fit your truck. He said it was very costly to get it done but did not specify on the cost. For 24's I would try to find a 295/35/24 or a 305/35. If you can find a tire you like in that size. This will give you about 4 inches of sidewall. You might have minimal rubbing at full lock left with the 295's, but it won't be as bad as the 305's. This of course depends on the right wheel offset. I like my wheels to be pushed out to the edge of the wheel well without sticking out on top.
