I ordered a set of 33.5-17-16 Hoosiers and they have 110 1/2 written on them. I set them next to a set of unmounted 34.5-17-16 and they look identical. I called Hoosier and they said the air the tire up to 20psi then check the circumference of the tire. I'm thinking they may be smaller than that at 5 psi, but I'm doubtful it will make 4 1/2 inch difference. They advertise 106" rollout. I guess I'll send them back. That part # is 18700 Hoosier, I'm thinking about ordering #18500 which is 33-17-16 with a supposed rollout of 104". I really think I need to get a shorter tire with the 4:10 gear.
