Hoosier 31.0/4.5-5 Tire

Can anyone confirm that on a wheel of "x" width that this tire will have a
31" circumference mounted with "y" amount of air pressure?

Right now I can make 30.5 with a Dunlop R6 and 31.5 with a Dunlop DCS but
I would like a 31" LR in my "toolbox" too and rather someone be able to confirm
that it will measure out to 31".

Thanks in advance!

My Hoosier 31.0/4.5-5 on a 5" wheel comes out to be 31 1/4.  My Dunlap DCS 10x4.5-5 on a 6" wheel comes out to be 31".  You can also use a 10x4.6-5 Vega Yellow on a 6" wheel.

You can use the Hoosier but you will have to grow the tire and I have not tried with the new Hoosiers.  I used to do the older ones but really have not had the time or patients to give it a shot and just bolted on Dunlaps.  ;-)

Yes, I bought a set of the 31-4.5x5 hoosiers and my LR was a little less than 31" on a 6.5 inch rim.  I had to grow it some to get it to where I wanted it, but you can get a 31" LR with the 31-4.5x5 tire.

Mounting tecniques will also have an effect on final set tire size. If you blow one up with no lube, no strap and a ton of air, chances of stretching the cords in the tire where it wont relax to normal is pretty great. Dirt compounds seem to be a little less prone to this but also will be almost impossible to shrink when you get them too big.
