Sadly my discount tires (america's tires here) put them at 32. I asked them to air up to 40 and it felt great. After about 20 miles of bumpy/rocky forest road they somehow feel better now, less harsh punch and more sidewall rebound. It could be me getting used to the bumpy ride, but I will add that to the break in procedure if I would get another set.

Before I got my Falken Wildpeak AT3/W in E load, I did a ton of research and read and reread that thread on LT tires. I have about 6k miles on them at 40 psi. It varies just a tad, but I’m not that obsessive over each psi. I am going in for service and will ask my trusted mechanic (Frank’s Import in Concord, CA) how they’re wearing and if they’re ok at 40. The tire pressure calculator pegged them for 44 psi. We’ll see. Only did a little off roading in Sedona (Outlaw Trail).

Also wanted to add-What weird timing for this thread! I just had a dream last night about driving super fast around corners and then sliding off the edge and looking at my tires showing that the tread had delaminated.

What does it all mean?!?!? LOL!

Hahaha just a dream...good tires and actually looking at them before your high-speed runs will net you to be fine...I read that dream as , drive fast, take chances! With the right tires & understanding of them, you're good to send it!

Hahaha! I have my other car for speed (BMW 330i ZHP 6 speed manual and very red!). But in my old age, I’m slowing down a bit. I get passed by Priuses! LOL!

Just got back from the shop, and 40 PSI for my tires are fine. (Falken Wildpeak OEM size E rated). No abnormal wear noticed.

A data point. I have E General Grabber AT/X and at 40PSI they feel great on a gravel driveway but a little spongy on the highway.

At 45PSI they feel bouncy on a gravel driveway but great on the highway.

Might try 42PSI.

Is yours in stock size too? Mine running at 42 psi would straight up bounce the wheels off the ground on shitty LA roads. My 4r is pretty lightly loaded at the moment, too.

Also update, based on inflation table for LT265/65r17, looks like even 35 psi is way above 4runner's max GAWR (3530 vs 3050)... Non of the inflation tables that I have contains data for <35psi, I guess it's unknown territory lol. Now I have put on about 300 miles on/off road, they feel significantly better behaved at around 37. I went through the same bumpy road few times with different pressure (just in case anybody lives around me it's wilshire blvd between Western and Berendo east bound), and 39 is the threshold for wheels to remain planted. I assume that will change when I someday load it up.

The other fun fact I've found is, yes load rating is the bottom line that anybody running LT should not pass under any circumstances on road. But manufacturers do not design their recommended cold pressure based on it alone. For HD trucks, the recommended pressure is much closer to the load rating required for GAWR; GX460, has its recommended cold pressure right at the load rating (only 10 pounds above). 4runner's 32 psi on 265/65r17 also puts tires way above its actual GVWR, so that must be because of other factors. I can think of corner grip, ride quality, dampening or even rollover resistance. For some reason, manufacturers prefer oversteer or understeer compared to rolling over (I would too), and more stiffness from the tire is definitely a measure. I will say as much as that original thread (LT tires require higher pressure) is very thoroughly explained, it left some unexplained things in its argument, eg. 5th gen limited load rating, GX460 load rating and etc. Also DOT completely ignored medium and large SUV sometimes put on OEM LT tires to boost offroad durability and capability, and proceeds to mandate the 46 psi requirement. Imagine running 46 psi on 285 on an FJ.

Don't know about you all, I'm gonna go with 35 psi as the hard deck, since anything below is undefined and I don't know if the correlation between load and pressure is linear in that region.

Been riding at 40 psi for the last 6k miles. Going for a short camping trip up to the wine country and will give 44 psi a try. Did a short in-town drive and it feels a bit stiffer and harsher of course. We'll see how it is on the fwy.

I need to chalk my 35's out... I'm almost certain that 36-38psi i'm running is way low (especially after seeing some of you guys running in the 40 psi range) for my rig... I guestimate that I'm between 6300-6700lbs for my rig as it sit so it's quite heavy and I can physically see my rear tires fairly deformed compared to my fronts..
