up at silver lake i run at 10 psi on the 265/75/16s. the tire looks completely flat, i wouldn't wanna run any lower with these tires. i got great traction you must air down for sand, you will get stuck. i dont think there much difference in traction between 8-12.
my friend on his toyota pickup ran 4 and kept getting stuck, he aired down to 2 and was better so he went down to 1 and did great till he lost a bead and almost rolled his truck.
hopefully i can go up there on the 4th and be a little taller and bigger/wider tires /forums/images/graemlins/deal.gif
