Our premium line K_plus is the KRAIBURG workhorse, with a variety of highly specialised drive and winter patterns for all trucks and buses boasting impressive grip and outstanding mileage in long-distance, suburban or regional traffic. The specially designed synthetic rubber compound is a pure SBR* /BR* blend. This makes the K-plus the endurance runner with the ability to go the distance in all road conditions where the primary requirement is for excellent wear resistance and high mileage. The high percentage of synthetic rubber improves grip in wet conditions, due to higher energy dissipation in the higher frequency range, yet without compromising on the potential to achieve exceptionally good mileage. The K_plus treads have the combination of SBR and BR to thank for their rolling resistance which is good for a synthetic rubber compound.
