14/31/15 firestone grooved rears...rim size...?

anyone running this size tire ....? and what size rim are you running....? lucked into a brand new pair .....will a 15x10 work...? thanks brandon

 

15x10 might be a little narrow for that tire to give proper support for the sidewalls. A 15x12 would be better. Industry standards call for the rim to be roughly 2" narrower then the section width of the tire for optimal performance. With the rim being 4" narrower, it'll bow the sidewalls out too far.
