|pastorscott||I always run my tires at max pressure for max MPG.. yes 50PSI rides rougher but much better MPG no doubt|

They are rated to 55 psi. So I thought I would give it a try and harden them up a bit. I had been running them around 35 psi. Ride is rougher, but I think the harder tire drags less. I know they will wear faster, but I am due to replace these now anyway.
What pressure do you recommend?

I have a 2.5" lift with 31" X 11.5" all terrain tires filled to 50 psi. My upstream O2 sensor was bad and my plugs, rotor and cap were all truly in need of replacement. I did the wires for good measure.
I don't have a cold air intake and I have an aftermarket, but stock exhaust setup.

|Timberline||Glad you got that 10 mpg jump. If the engine light was on, I'm guessing it was the oxygen sensor that was crapping out on ya!!|

I know this has been beat to death, but my TJ 4 cyl dropped to about 8.5 mpg and the check engine light was on. I ran by my local Auto Zone and they did a free diagnostic. I ended up spending about $105.00 for a new oxygen sensor, cap, rotor, plugs, and wires. Two hours later the check engine light was off and I was getting about 18.5 mpg!
Way to go me!
