Whoooooo! My post is from a former mechanics that became an engineer, but there is no need for these i am better than the keyboard mechanic with a different opinion. The engineer-at Toyota calculated the best tire pressure for the normal operating conditions of the tacoma, 35 psi is too much as the stock tire only touches in the middle when inflated. How do i know, i used chalk and at 29 psi i get contact on the whole tread with. But who am i to know....

Yeah I've seen engineers at aem/k&n **** up an intake and Toyota engineers sign off on it and sell it as "trd".... Right after they got caught selling an illegal "trd" intake for years before made by afe... Cool story tho
I assume the u bolts are supposed to be torqued to 35ft lbs as well.

Let's not forget the absolute joke of a tread pattern on the bfg, and bfg Ko1..... More engineers asleep at the job forgetting rain happens.

Careful 'Pauly-B' I'm with Bojangles here, at least what he had to say made sense. And carried a degree of grammatical correctness.

I am french, so there goes grammatical ****. It was rude of him to assume someone he doesn’t know is talking out of his hat. I usually don’t comment unless I know what i am talking about

Put your hat back on, it's all gravy.
I know what I know and we now all know what you know.

Yeah you must be very well educated to be a tire tech, at least i have diploma to show for what i know, and i have been offroad for years, many tires i have tried and tested, many build under my belt from 1 ton jeeps to camaro and tacoma...

We all come from different backgrounds and have knowledge about stuff. I’ve met lots of people that are college educated and can’t handle social situations. No ones saying you haven’t built things. You can run your tire pressure at 29 psi I can run mine at 33psi @Bojangles can run his at 35psi. PG&E runs the DuraTrac’s at 40-45psi. Like @Bojangles was saying there are lots of reasons why you would run the PSI differently. Depending on your weight and needs it could change. It’s not a one pressure fits all.

View attachment 22747 Not to butt-in here but I run my tires at 34psi cold......they warm up to about 37psi and that's where I've noticed best tire wear and ride!

Load range C tracs....

I vary the pressure based on loads, weather, terrain, and how I'll be driving.
I also account for front/rear weight bias and take turning vs sidewall flex into the maths.

Having no swaybar alters my ride as well, still carved up a back road yesterday hauling a few hundred lbs in the back.

Definitely have to adjust based on loads and weather. I remember a few years back folks were blowing tires and having accidents......if I remember right and correct me if I'm wrong but all those were attributed to low tire pressures.

Could be, low psi creates more rolling resistance, which creates heat, which expands the air inside the tire, which can cause issues especially when combined with the low psi already causing the inside of the sidewall to start failing. I've seen some tires come off with under inflation wear patterns being evident on the tread face, and the inside of the carcass has tons of powdered rubber in it from being under inflated and iirc the sidewall rubs against itself under the weight of the vehicle at the pinch point. So it makes for a perfect storm.

The Firestone fiasco was brought up recently in a pm. That was lack of long term r&d. Belt separation blowouts.... Firestone blamed customers for under inflation, I guess they said ppl filled em hot, not cold...article didn't specify. Or maybe the placard on the jamb was incorrect, again the article I read didn't specify.
The Firestone fiasco was horrible tho.
