ABSTRACT:
In an inflated tire and rim assembly (68) the improvement is in the profile (42) of the tire (40) having an aspect ratio (H/S) ranging from about 0.80 to about 0.90 and the maximum section width (S) is located at a height (h) of more than 55 percent of the section height (H), with the tire (40) being mounted on a rim (66) having a design width (DRW) of about 65 percent of the tire section width (S), while the width (TW) of the tread portion (50) is greater than 70 percent of the section width (S). The inflation pressure of the assembly (68) is a minimum of about 25 percent greater than the inflation pressure of a conventional profile tire (10) of an equivalent size and load carrying capacity.
