The A501 is a snow tyre from the Aplus brand. The perfect tread compound remains flexible at low temperatures to ensure grip on the road in winter conditions, while reducing rolling resistance. The bionic tread pattern makes the block stiffness more consistent with the optimised deployment of "Z" sipes, offering excellent grip on snow and ice. The wide circumferential Zig-Zag grooves, and convex at the bottom, improve traction, shorten braking distance, and increase stability on snowy roads.
