Titan International and the recently acquired Carlstar Group have introduced Variable Pressure Operation (VPO) Technology, a flat-proof technology that, according to Titan, offers a versatile solution as an alternative to tweel wheels and other airless polyurethane spoke wheel options, by providing the ability to effectively operate machinery at various inflation pressures – even down to zero psi. The tyre maker is presenting VPO for the first time at Equip Exposition, which is taking place in Louisville, USA between 15 and 18 October.
