Abstract
An improved tire/vehicle system for an automotive vehicle has two pneumatic front tires and two pneumatic rear tires. The rear tire treads are wider than the front tire treads and are divided circumferentially into first and second portions. The first portion of each rear tire tread has a width between 50% and 90% of the rear tire's tread width and is arranged to longitudinally track at least a majority of one of the front tire treads. The second portion of the rear tire tread does not longitudinally track any portion of such front tire tread. Each rear tire tread has a tread groove pattern that is asymmetric in character, the respective net-to-gross ratios in each of the first portions of the rear tire treads being at least 27% different from the net-to-gross ratios of their second portions.
