Sorry, that post makes no sense. Reduced tire pressure, even BELOW the mfg specified will result in better braking performance. Instantaneous turn-in response is greater with higher pressures, but with a sacrifice in ultimate turning grip (reduced delay, reduced friction). AND a properly inflated tire will have the entire tread surface in contact with the road, wearing evenly instead of down the middle like an overinflated tire will. All three of these points are tire basics that anybody who uses a race track knows. Why do you raise your tire pressures? It is to reduce the friction with the road! While this gives you reduced fuel consumption, it does not magically give you extra friction when you try to stop and turn, and it does not magically make your rubber less proned to wear.
