I have a 1996 polaris sportsman 400 4x4. I all ready have a 2 inch lift kit all around with epi heavy duty springs in the front. I plan on upgrading the tires to some gorilla silverbacks 27" or 28". my biggest question is i also wanted to get a set of 12" wheels and was wondering which rims are the lightest. most manufactures or sale sites don't list weights that i have seen.
