FYI...

I have some specs for the chrome steel wheels on my '02 Sportsman 700, with Goodyear Rawhides mounted.

front ..12x7* wheel, offset 4 1/4 + 2 3/4......29 lbs. each
rear....12x9* wheel, offset 5 3/4 + 3 1/4......39 lbs. each

*note: as measured at outer most edge of wheel not the bead seat.

By my calculations that would make my front 1/2 inch wider and the rear 1 1/2 inches wider if I get the Vision 160s 12x7 4+3 (f) and the 12x8 4+4 (r). That's if the offset on the Vision is measured the same.

I don't have the weight of the chrome steel wheels alone.
