Wow, I never even heard of that size before!?

At first, I thought it was a joke. Looks like an interesting tire size, sounds like it is close to a 9.00X16?? How many inches tall are they?
I wish there are more tire options out there in the Q78 and 9.00 x 16 world, basically 34 to 36" tall by 10 to 11" wide. My dad ran 9.00x16 and Q78 x 16 on our 4x4 wrecker (single rear wheel wrecker) for many years and I learned to love the tall skinnys too. I run 315/75R16 all terrain's for long distance out of state trips but for local mountain trips you can't beat these Q78's. They keep the track width somewhat narrow for the narrow mountain trails, chew through snow like a snow blower and deform around rocks when aired down like silly putty. For being biased ply they really don't handle too badly on the highway either. 8,000lbs of truck and camper on top of them might help keep them at bay at highway speeds. Tire life is pretty sucktastic though, typical of Super Swampers. Again, I wish Super Swamper wasn't the only game in town for tall skinnys
