Wide base steer tires psi?

[Pete379]

Around here we run 385 on our dumps trucks. Mostly highway miles other then the quarry's and job sites and after 5 years of altering pressure I've been having the best luck with 125 cold on a 130 max cold tire. It has cut down on outer edge wear significantly. In the past at anything below 125 I would have to constantly flip on rim and rotate from side to side every 10k or so just to get 50k out of a $700 tire. At 125 i see 80 thousand now and much less maintenance to get it... Our tred is not as aggressive as yours though
