theres more air in front and still does not come close. i could put 8lbs in front and 2 in the back and still is the same.

 

Did you get new rims with your tires? Are the rims the same width? Are the front and rear tires the same width? If your front and rear rims are the same width and your rear tires are wider than the front tires, the rear tires may balloon out more in the middle causing a bigger diameter. Just a thought.
