I've got 275/55 R18's on and I really like them. They don't "bulge" out to much from the side of the rim and I didn't have to trim any cladding. The tires areToyo Proxes S/T's and you can find them at https://www.tiresavings.com/index.php. Just put the tire size (275/55 R18) and they will come up. Take a look at my gallery, I beleive there are a couple of pics. in there.
