MPG experiment....1976 Dart Lite

Don't air your tires up to 44psi. That's the max psi you should put in them for the max weight they can carry. Sure you'll get more mpg but you'll be riding on the center of the tread patch to do so. By eliminating some of the tires designed contact patch ( also figured in to the max psi... only for greater weight ) you are getting rid of steering, braking, and cornering traction. At highway speeds you'll also increase your chances of a blow out due to too much pressure. Has anyone seen a picture of a regular radial tire at highway speeds? That is some scary $h!t. The low profile tires or ultra proformance tires aren't anywhere close to showing the amount of deflection that the "normal" (for most of our cars) tires have... and that's at the correct psi for load condition. If I find my adapter for my cell I'll snap a pic and post it.
