One of the most fascinating aspects of engine cams is their cam profile, which defines the shape and motion of the cam lobes. The cam profile directly influences how quickly and how far the valves open and close. A cam profile with a more aggressive shape will allow the valves to open wider and stay open longer, resulting in improved intake and exhaust flow at higher RPMs. This enhancement can lead to significant increases in power output.

The R indicates that the tire is of radial construction, which is the most common type today. Radial tires have plies that run perpendicular to the direction of travel, providing superior flexibility and improved handling characteristics, especially at higher speeds. Finally, the 15 refers to the diameter of the wheel rim in inches. This means that the 33x12.50R15 tires are designed to fit on 15-inch rims, making them compatible with a range of vehicles, particularly lifted trucks and off-road SUVs.
