We took our Liberty on it's first real road trip. It was about 475 miles round trip. That included going over the mountains twice. We averaged 20.5 mpg going over. Coming back I was pulling a 12ft boat. We averaged 19.2 mpg. I thought that was very good. We average 17-18 mpg around town.

You need to go higher than 33 pounds. I ran 36PSI actually.

Wow, up to 33 pounds...were you running them lower? I thought 35-38 was the right area for stock?

I run them at 42psi (44 being max) (2004 4x4 sport)
I averaged 23.7 Mpg on my roadtrip last weekend (60-65mph)
also am using mobile 1 synthetic oil, used only chevron gas, and only accelerated like an idiot one time

I run 35psi on mine with 235's. Keeping the RPM's under 2500 when you're doing stop and go travel really helps too. I've been averaging around 18 to as much as 19 in the city...with the A/C ON!

I would not run them that high. Very bad idea IMHO. I have the evic that tells me the psi of each tire. On the same day Ive seen them as low as 34-35 and as high as 39psi. The psi will change alot with lots of HW and temp change. O:)

Pretty good! How did it tow? What's the weight of your boat/ trailer?

I hardly knew it was back there except on steep hills. The last climb to the summit we slowed downed to 55mph. That was witth the O/D turned off & running about 3000 rpm. The boat is a 12' aluminum Duraboat on a galvinized trailer. I would say 700-800 lbs.

If max cold PSI is 44 there is nothing wrong with inflating them to 40 PSI
if max cold psi was your 35-38 they would list it as such

Yes, that's nothing! A boat would be fun.
