I have the BFG 315’s and have been running them at 50 psi. I have 12k on one pair, the other had to be replaced due to an alignment problem, but the original pair at 50psi have a even wear pattern. On a “cold” morning (that’s 40degrees for me) the Hella TPM says they are at 43 psi which does “look” low. I drop them down to 30psi for 4x4 trails and washboards.
EV-2 build is now complete, (yeah right).
