gas mileage DROP!!

Before I lifted the VX, I went on a 3 hour road trip going between 80-85 mph, and got 22 mpg.......

Now I put the 2 1/2 - 3 inch lift, and went from stock tires to 31's and I am only getting 13-14 mpg(freeway miles, and only 75mph)!!!!!!!!!!! What is up???!!

Anybody else have this problem? We are going to check the O2 sensors, we replaced the spark plugs(back to the original ones, some dork had put the 99cent Champion spark plugs in), any other ideas of things to check???

We have lifted other vehicles before not mpg didn't change that much! I don't think this is normal, but if it is...lift comes OFF!
Thanks

Uhh,

when you lift, and you put on bigger taars, its going to drop your MPG.

More air resistance

heavier taars.

Didn't affect mine that much. Especially on the highway. Once up to speed you get a gyro effect.

I sense a gear change and ...um...possibly ....A LOCKER!!!!! You missed my wedding today...YOU SUCK!!!!!!.......

the after shot...I was ...um...indesposed
