We got talking about our van's tire pressures on and off-pavement on another thread, decided to bring it here for full discussion. It seems I've been running my tires lower on pavement than others.
Curious as to;
--Your vehicle make/model/year/2WD or 4WD. Vehicle weight unloaded/loaded if you know it.
--Your tire brand/model/size
--What pressures you're running on-pavement and off-pavement(specifically for what terrain; graded gravel/forest roads; rating 1-3, rocky terrain; rating 4-6+, mud, snow, sand. Ratings taken from here; http://www.jeeptrailinfo.com/trailratings.html )
--How's the tire wearing?
_______________________________________________________________________________________
I'll go first;
--2007 Ford E350 RB SuperDuty 6.0LTD w/ UJOR 6" 4x4. Loaded wet with 4 people and gear at 9650lbs(4800lbs F, 4850lbs R)--will have to weigh again unloaded and wet.
--Toyo M/T 35x12.50-17 E-rated
--Been running 35-36psi(COLD) on street and empty, 38psi cold and loaded. Same for gravel forest roads rating 1-2, down to ~25psi on rocky terrain like the White Rim Trail, and others rating 3-4+. Haven't been in mud/snow/sand with this rig yet.
I just spoke to my Toyo tire guy. Tire specs at 3640lbs load per tire, 10ply tire. Suggested pressure is 40-50psi cold, max is 65psi. He thinks I was ok for 2wks fully loaded at 38psi cold and loaded. He'd suggest bumping up a bit depending on weight in the rig. I'll go up to at least 40-44psi cold when empty, probably 50-55psi cold if fully loaded.
--Tire wear even across the tire(why I didn't see any issues running 36-38psi cold).

--60psi but "I ran around with 55psi for a few days in town and it took the edge off the ride with little potholes and what not." "Yankee Doodle Lake on a 2/5 road - very easy but constantly bumpy. I dropped it to 35psi but really should have gone even lower - no extremely sharp rocks. I'll try 25psi next time out."
--Tire wear?

--"Running 44 psi street is still harsh but my van is also totally empty. Went to 35psi offroad in death valley but the washboard was killer. Going to try 25 or 30 psi on the next outing."
--Tire wear?
