Tire pressure?

[BailOut]

4MPG,

Your logic is flawed in several ways.

1) Center tread wear has not been an issue since the invention of the steel belted radial. Please update your personal cache of information.

2) I already mentioned that dropping pressure by a significant amount will help traction, but it does so through a pure "grippy" fashion rather than a tread-clearing fashion and will eat through your tires rather quickly. While this technique can certainly work on a clean, dry track the real world is a much different environment.

3) Your ideas on everyday traction seem solid except for one glaring issue: Millions of miles of road testing - that is testing as opposed to simply regurgitating what one was told one time - have shown the exact opposite to be true. Even police departments are starting to mandate pressures as much as 50% higher than the old recommendations for better handling and longer tread life.

The one that runs at higher pressure, every single time. This has held true over millions of road miles of testing, in every kind of environment and on every type of vehicle it has been tried on. You certainly have the freedom to believe regurgitated rhetoric but for my money I go where the actual testing has been done.
