    Isn't that a little low? I bet you could increase your fuel economy percentage by almost double digits if you filled them up to 42ish...?

    Mitsubishi recommends 35# for 14" and 32# for 15".

    RT43 are cheap and come in 185/60 size which is closer to OEM. Good grip and decent MPG they're actually rated higher than Defenders on TireRack

    I run 45 psi in mine.

    That's for ride comfort and sluggish drivers. If you actually want your car to perform then you need to add about 4 PSI (as with any passenger vehicle) to their numbers. Also the # recommendation is wrong when you buy tires that are wider or have different load dynamics. I had to run the stock 14" at 42PSI for them to feel firm on corners or highway speeds. They are very bad in the rain.

    On OEM steelies we had to get 185/60R14 RT-43 to 48/42psi F/R, at 42psi tire was squirming in corners too much on 4.5" rim. Wider rims or tire with harder sidewall would allow to run lower PSI.

    Even with 15x6.5" wheels and 185/55 tires that are 7.?" wide I have to run at 36psi in the summer and 38psi in the winter... And, that's with Toyo Summer Tires

    Just shy of 32k miles.

    I think the TMPS sensors are set too high - the tires all wore more in the center than the edges of the tread. Can this be adjusted?

    If your tires are wearing in the middle more than the sides, then that is because you put too much air in them or you do all highway driving and no higher speed cornering.

    The TPMS sensors are just idiot lights for people who don't check their tire pressure. You have to manually adjust your tire pressure up or down at the pump. Normally they trigger the (idiot) light on your dash when the pressure is 25% below the target zone.

    EDIT: Always keep a tire pressure gauge in your glove box and check your tires anytime the seasons change at a bare minimum. I do a walk around every fill up and or morning. If I hit a curb or run something over next time I get out I also look at the tires. If one looks like it's bulging more than the others I check the pressure. It is normal for a tire to lose 1 PSI a month. Air pressure also goes up or down 1PSI for every 10 degrees (F) that the tire changes. I keep my tires around 38 PSI. When it started to get hotter here in FL I actually had to let 2PSI out of each tire because it went from 70 degree average to 90 degree average in the course of a month. They were getting too stiff on the highway with the heat and friction. The fronts get hotter than the backs.

    A good test to understand this is to check your pressure in the morning, then around noon go drive your car for 10 miles and end with some higher speed highway driving and then check the pressure. An increase by 4-6 is quite normal. This is why the tire is rated with a maximum cold PSI, because they are accounting for expansion from heat...

    EDIT 2 By the end of the month I'll probably drop my front tires to 36PSI as we are seeing 105F degree heat indexes here and the roads are closer to 165F degrees in the day.

    Wow. That's some impressive heat on the road. Any chance you have access to an infrared thermometer?
