Falken wildpeaks 305/65/r18 tire pressure

I searched and couldn't come up with anything. If you have these, what tire pressure are you running?

Answers will be all over the place.

You can figure it yourself though: https://toyo-arhxo0vh6d1oh9i0c.stack...s_20170203.pdf
Start on page 11.

I'm running my 325/65r18s at 35f and 30r. That's higher than I calculated, but looks pretty good. Yours are rated a little less (3525lb @ 65psi), so somewhere around there or a little higher should work.

Rear seat removed to make room for storage and bikes. King or ADS shocks with 700 lb springs, ~2" lift (may cheap out though). Rear leaves, maybe air bags. And more!

I've run 35 psi front and 35 psi rear in all my vehicles for 30 years. Regardless of tire make, tire model or tire size. Regardless if car or truck.

That said I'm running 40 psi front and 40 psi rear in the Nitto Terra Grappler 275/65/20's on my Tundra. To me watching the wear is as important as anything . Also, your tire's air pressure is part of your suspension "system." So far after 22,XXX miles on these Nitto's at this pressure the wear pattern looks perfect. Note that I don't haul much in the Tundra. The very occasional 400 pound trailer with 500 pound motorcycle. But that's only 1,000 miles of the 22,XXX.

YMMV.

I'm not completely useless. I can always be used as a bad example.

I'm running 35F/35R but may move to 40 if I see more wear than I expect. Im running 65's vice 70's but got 80K out of my last set on/off-road. Cheers
