Tire Pressure Control International Ltd. (TPC International), based in Edmonton, Alberta, Canada, manufactures, assembles and distributes TIREBOSS  Tire Pressure Control systems to the truck transportation industries. 

Tire Pressure Control systems, incorporate Variable Tire Pressure (VTP) technology, also known as Central Tire Inflation (CTI), to provide for the electronic inflation and deflation of tire pressures from the cab, while the vehicle is in motion. The ability to match tire pressures to vehicle loads and speeds results in reductions in vehicle operating costs and significant benefits to the truck owner and driver. Equally important are the benefits realized by road authorities, as road damage is significantly reduced, resulting in lower maintenance and construction costs. Many forestry and oil industry companies have increased hauling days resulting from improved flotation and vehicle mobility. 

TPC International commenced operations in 1996. Brian Spreen and Les Hinz are principals of the company and are the President and Vice-President respectively. They were instrumental in the implementation of the first Tire Pressure Control systems utilized in commercial truck transport applications in North America. Combined they have over 24 years of experience in applying VTP technology for the benefit of various industries around the world. 

The company has TIREBOSS  systems operating throughout North America, Europe, Asia, Africa, and Australia; primarily in on/off-road applications in the forestry, oilfield, concrete, agriculture, and power utility industries. 

Additional applications include highway transport, in conjunction with special government programs allowing extra payloads on weight restricted infrastructures. 

The continuing success of the company is attributable to quality products, dedicated employees, a strong commitment to product support and complete customer satisfaction.
