35" Cooper Discoverer STT Installed

[yat74]

I put them on the other day and they look awsome, pictures to follow soon (when I finally put on the RRO rock rail super sliders). The bigger tires make the truck, can't wait to get them offroad. Some things I have noticed since putting them on...Only minor rubbing when steering wheel is fully turned to the left. The only major thing I have noticed is a huge decrease in MPG. From reading all the posts on 35" tires I was prepared to lose some MPG but I think that what I'm getting now is alot less than before. I'm still trying to get an accurate MPG figure as this is only the first tank on the Coopers. I have been keeping the jack rabbit starts of the line to a minimum and speeds under 65mph. All in all I am very happy with the tires and I didn't buy the H3 for its fuel economy anyway. What pressure should the 35's be inflated to for highway driving? Offroad I was told I could probably go down to 12-15psi with no probs. Any suggetions?
