Tire PSI's??
In the summer I run 35 - 38 psi
In the winter (meaning snow) I run 25 - 28psi
p.s. These are cold psi's!
In the summer I run these (35 - 38) psi's and get 21 - 24 mpgs.
In the winter & 4wheeling I run these (25 -28) sometimes lower according to the snow/mud depth!
What psi's do you run and do you think it makes a difference?
Opinions Please!

Of course it makes a huge difference, in mileage, handling, cornering, stopping, tread wear, safety (look up hysteresis,) but it is totally dependant on what SIZE tires and a lot also depends on the rim width and sidewall construction of the tires too.

This is one of the best articles I've seen on how and why regarding tire inflation. Good stuff. http://www.thedieselstop.com/content...re%20Inflation

I run about 32 psi most of the time. At that pressure it seems to cut down on the spool-induced tire chirping in the rear. Anything in the 20s and it chirps like crazy. Usually run about 12 psi off road. Tires are 32x10.50 Swamper Radials on 15x8 rims.

I've been running 26 rear 30 front on the 35s with 15x8s, they need less pressure to wear right but I can really feel it if I go lower. Slows things down and handles like crap. I run it up to 28/32 if I make a trip, that feels good but only the center of the tread wears. 10" rims help this quite a bit, but I didn't want them for a number of reasons. That's the drawback for big tires on a light rig...

i have stock 1994 ford explorer rims on my yota and during daily driving i run 32-35 psi
for wheeling i drop the fronts to 25 and the rears to 20... have run it on the street and freeway at that pressure for well over a week with no ill effects either.. the truck is very light

I typically run my 265/70/16's at 32 psi year round and I check them frequently. In deep snow I may deflate them to 24-26 psi.

I run 37 psi on the OEM Dueler H/Ts in summer, and 35 psi on the REVOs in winter. Most tire manufacturer sites have specific psi ranges for each tire they make. Check the site, and adjust according to the way you drive.
