The designers of the Korean tire maker gave the Nexen N’Fera Primus QX an asymmetric design that is meant to improve the tire’s performance both on wet and dry pavement.

One of the four circumferential grooves is made somewhat narrower than the others, which leads to good lateral stability combined with quick water evacuation from the contact patch. The small slit-like sipes that diagonally dissect the tread blocks are meant to increase the traction of Primus QX on wet and slippery surfaces, as well as to maintain the optimum tread stiffness. The wide slanted grooves as part of the water drainage system are designed to reduce the risk of hydroplaning and increase the tire’s stability on wet pavement. Thanks to the bridges between them, the shoulder blocks are less likely to deform under lateral stress, which yields in better handling response during lane switching and maneuvering.

The Nexen N’Fera Primus QX tire model was presented in China in 2020, becoming a great addition to the tire line, hitherto represented by the Nexen N’Fera Primus model.
