A. First, properly inflated tires are safer, last longer, and offer a balance between fuel economy and traction. Second, tires are one of the top expenses for trucking companies. Third, tires are made of rubber and lose air through their walls, slowly, even if there are no holes in them. Finally, it is neither easy nor fun to check all eighteen tires on a big rig when it is hot, cold, rainy, icy...So let us say that checking tire pressures is not always a high priority for drivers.

In fact, numerous studies have been performed studying the occurrence and effects of improperly inflated tires in the trucking industry. These studies have shown that a large percentage of tractors, and especially trailers, have underinflated tires. While specific results vary, it is confirmed that all fleets leave some money on the road in the form of blown tires, excess tread wear, and decreased fuel mileage because their tires aren't properly inflated. Just ask any maintenance manager, and he will confirm it.

As was proven in the recent TMC study, ATIS mitigate this issue on trailers (and may, someday, on tractors). With proper maintenance, ATIS, like Aeris by Stemco©, inflate trailer tires to the appropriate pressure, even when they have developed leaks from road hazards. To finally answer your question, the real, proven benefits to ATIS are increased fuel economy, reduced tread wear, fewer blowouts and roadside calls, and peace of mind.
