31x10.50_15 pattern width??

[xjfan]

I'm asking because at the Big Cypress National Park, they require a minimum 9" wide pattern.

I've checked local tire shops, about 4 of them and when I measured they only measured 8" to 8.5" wide.

Would be nice to know which 31's have 9" wide pattern..

Here's what they are looking for... ORV Permit It's on page 3.

Was able to score a set of 33's but need to lift it about another 1.5". Seem like a lot of work to make them fit..

im pretty sure both sets i have had measure out more than 9". my dick cepek FC-II were wide.
my general grabber at2's are at about 8.5-9" wide.

otherwise a 31" x 11.5" which is common on super swamper tires.
