On the dunes all terrains work the best. Mud tires work ok but not as good. Shortshift - if you aren't having to air down then you aren't on much sand. Hit real dunes and I guarantee you'll have to air down! There's a sign at the entrance to the dunes here in Michigan that says max tire inflation 15 psi. Lots of newbies don't air down and get stuck within the first few hundred feet of the entrance road. [/QUOTE]
Steve,
I've been going to Glamis sand dunes in So. Cal for over 20 years. Raced MX for over 15. Had a mud truck, pulled toyotas out of Azusa canyon when some were bogged down to the floorboard, and had water to the drivers seat. No biggie, just like others here. Dont enjoy tooting my own horn, but establishing some experience. I am familiar with sand.
I have run A/T tires on this truck for 60k miles (BFG of course), and now have Mud tires (Dunlops), for 42 k miles. Had gumbo monster mudders on a previous truck.
Have been to glamis numerous times w/ this truck, also my property in Az.
Now the point:
The A/T's were slightly better in sand due to they dont sink in as easy. The Muds do tend to sink in easier, but with enough torque to keep them spinning slightly faster than your speed, they dont sink that bad.
The loss in the sand is far outweighed by most other types of terrains, where the muds will eat up the A/T's in soupy mud, climbing hard pack desert terrain, loamy dirt, snow, and some say ice (I cant say there). Also, the muds, dont fling rocks all over your truck like the A/T's do, and I have found in the rain, that my A/T's were no better than the muds on the street, in fact, the muds seem to be better in rain, and they track better over the rain grooves on the freeway better than the A/T's did.
Bottom line is the question was about comparing the 2 tire types w/ an emphasis on sand. My response is the Muds are not a slouch in sand, and much better overall than A/T's IMO.
Which tires are on hummers in the desert sands of Iraq? I believe they are may be Michelins, but they are aggressive like muds, not A/Ts.
