For those running 285/75R18 tires, what brand tire and what PSI are you running? I got a great deal on Falken Wildpeaks in the size, but want to make sure I get the fill right without having to experiment for a couple of weeks.

I have Cooper's and I run them at 37
Thanks.

Just put some across town miles on it and PSI should come down - getting same gas mileage with 3 inch taller tires - likely running too much on centers. I was expecting a .5 to 1 mpg drop.
