It's not the tire that makes your tire/rim combo look so skinny it's your rim width. Most tires on a 8" wide rim will look skinny.
I personally think the H2 tires stock are too skinny and if lifted I think you need at least a 10" wide rim if not 12".
There's a guy on here who has a 40" tire on a 20x10" rim with a 4" lift. I think this look is perfect.
