Kumho's well-known Wintercraft Wi31 studded tire now has a new counterpart: the Wi31+ model. The most noticeable difference between the two models is the increased stud density in the Wi31+. In two of the most popular sizes (195/65R15 XL & 205/55R16 XL), the new tire features exactly 200 studs instead of 150. This enhancement maximizes braking and handling performance on icy roads and in demanding winter conditions. The latest rubber compound technology has been used in the production of this new tire.
