Wish i had a narrow set of 16s then..

 

I use 31x10.5x15 firstones A/Ts as mentioned above.Plenty of tire for the eastern N.c beach. I air down to about 14lbs and no problem. Even down at Avon heading south in the soft sand we never have a issue.

 

sounds crazy doesnt it ? lol But in all honesty I have run thorbirds and tsl's both is the sand down to 1-5 psi many times ...the side wall is so stiff they wont even start to flex until there down to at least 5 psi . But like crawler said the 22re isnt powerful enough to climb the big hills .. but still alot of fun . I love the dunes
