I have those on my H3T still at the moment and I run them at about 38-40psi

 

When I ran the bridgestones, I set them all to exactly 38 PSI, never had any issues.

Let me make my ride height suggestion easier to figure out. Allinement has nothing to do with over raising the fron T Bar geometry, it is only a measure of your fron tires camber and toe. When you look at your truck from the side, if the nose lower in the front? We call it the GM factory rake. If the front looks a lot lower, forget about checking for overadjusting the T Bars. If it looks level, pop off a wheel cap and use a tape measure.

 

Run the pressure it says on the door sticker. 35 psi. You're riding on rocks and I'm sure with that much pressure only the middle of the tire is touching the road. Overinflation is not good for the tire nor the suspension system.

 

I keep forgetting to look at the sticker inside my door... 35lbs? Then why does the tire itself say 50lbs, I guess that is just the max you can run the tires at? I know when they did the alignment the adjusted the camber and toe. It does have a slight rake to the front end but I will need to do the measurement. Does anyone know where I can see pictures of doing this measurement? It would give me a better idea of exactly what I am doing.

 

The pressure on the tire is, as you say, the maximum pressure that the tire manufacturer determines. Each vehicle manufacturer then comes up with their spec for recommended tire pressure, presumably based on vehicle weight, tests, engineering calculations, etc.

Practically speaking I don't know of too many people who run the OEM 33" tires at 35 psi. Among other things the tire pressure monitoring system (TPMS) seems to spaz out (that's a technical term) more frequently with tire pressure below 38 psi. As you increase the pressure you may find slightly better gas milage (and perhaps not) but also a firmer ride and possibly uneven tire wear.

 

YES the max psi listed on the tire it's self is for the tire alone. The higher the psi the beter mpg you get but the ride gets harder & you cause uneven tire wear & unsafe handling. Any light truck/ SUV I've seen in the last 20 years has a reccomended psi of 35 on the door, I tend to run 38 on my T & 34 on my work car cause it drives on the beach as much as pavement

 

Thanks for all the advice, and please let me know if anyone finds pictures on how to measure for the frond end rake.
