I just put 26" Dirt Devils on my foreman 450 S. These bad boys are 6 ply. What air pressure are you all running in these biga$$ tires?

 

I run 4-5 psi Frt. and Rr. I ride in different terrain though. My riding is done in the foothills of the Appalachian Mtns. of SE Ohio. Lots of clay mud, sandstone, hardpack (up on the ridges).
Hope this helps some. Later, Mike.
My bike is a '00 Foreman-S/ tires are Titan 589 M/T's 6 Ply Rated

 

Mike, thanks for the input. Near my house is dirt riding, up higher we get into slickrock, gravel, shallow mud and snow. I had guessed 4 lb fr/r, with more if the racks are loaded, as with game. The footprint of these tires stays the same no matter how much air they have, probably because 6 plys make 'em so stiff. Nothing is gaines, say in sand, by letting air out. How do you like those Titan tires? I heard good stuff about them.
