Small differences in tire inflation and pairing can affect both tread wear and fuel economy. Even a ¼ inch variance in tire size can cause the larger tire to support a greater load, resulting in accelerated tread wear and increased heating on the larger tire and scuffing wear on the smaller tire. These factors increase rolling resistance, which drastically decreases fuel economy. Innovative Products of America (IPA) has launched several products to help consumers solve these common tire problems.

The Mobile Tire Pressure Equalizer, pictured above, is designed to quickly inflate or deflate up to five tires at a time. The equalizer is equipped with two integrated high-capacity air regulators and two high-resolution, glycerin-filled pressure gauges for consistent and precise tire pressure readings. The system is mounted on a welded steel cart with pneumatic tires and features wheel-specific, color-coded hoses with corresponding panel indicators and convenient hose hangers. 

IPA is also introducing two Tire Comparators. The type 1 tire comparator allows users to compare tire diameter on single and dual-mated wheel applications. The comparator can be adjusted to work on tires up to 48 inches in diameter and can reach the wheel wells, including the inside tire in dual wheel arrangements. The tool features standard and metric measurement increments for mounted and non-mounted tire pairing. Made from lightweight aluminum and featuring locking slide adjustment for consistent readings, type 1 can be used for preventative maintenance or as a service tool for tire service.

Tire comparator type 2 also compares diameters on dual-mated tires. However, type 2 has a sliding tolerance gauge that requires no measuring. Users can simply hold it against the tire and slide it across the treads for a quick pass or fail test. Special tread wear adapter gauges are available for different rim sizes.
