Characteristics series VR
This wheel series has a closed rugged cast iron wheel centre and firmly bonded cast Vulkollan® tread, hardness 92 Shore A. The bonding onto the grey lacquered wheel centre is perfect and realised by chemical reaction. The relative thin tread is characterised by high resilience and grip, high load capacity and fine rebound resilience (very low permanent deformation over long endurance times). The wheel centre is resistant to sideways- and peak loads.

Applications
For extreme driving-applications at intensive use, where reasonably high requirements are made to rolling comfort and low rolling resistance. Also when certain chemical substances, greases or oils play a part.
