Looks like Procomp makes them in 18x9 with a 0mm offset. (5"BS). These would stick out about 1.5" beyond the fenders (not counting the tire). If your Tundra is leveled or going to be leveled this wheel would allow you to run a 33x12.50R18 or 295/65R18. If you select a wheel with an offset in the 35mm range your leveled Tundra will be able to fit a 295/70R18 (roughly 34" tall).
