If you're looking for a tire to switch back and forth on another set of rims rims I'd go with a 15" light truck tire like these..
TRAC GRIP II R408 Mud Terrain LT & SUV | Thunderer Tires
In that case I'd look real hard at those thunderers... buuut then we're back to garage height.
Could.. or you could build another garage!Yep, but I could change them out and then load up. All outside. Then swap again when I got home or do it where ever I was going to ride.
