LT215/70R15 Kumho Winter PorTran CW11 109/107R

Winter PorTran CW11 Winter

The Kumho Winter PorTran CW11 is a dedicated winter tire engineered for light commercial vehicles, vans, and light trucks that need to keep working through harsh Canadian winters. Built directional and studdable, the CW11 pairs a silica-based winter compound with a transverse groove design — central V-shaped grooves angled 40-45 degrees — that channels snow and slush out of the tread for a stronger bite and shorter stopping distances. A reinforced breaker-strip ply adds carcass rigidity to handle the higher load ratings (available in 6-, 8-, and 10-ply LT configurations) that fleet and commercial vehicles demand, without sacrificing wear life. For drivers who need the extra margin ice and hardpack conditions can require, the tread integrates an optimized stud hole pattern so metal studs can be added for maximum traction on glare ice. The tire carries the Three-Peak Mountain Snowflake (3PMSF) symbol, certifying it meets the industry's severe-snow-service performance standard. Positioned as Kumho's commercial-duty winter option, the CW11 targets delivery fleets, contractors, and other light-truck operators who need dependable snow and ice traction, load capacity, and durability in a single winter tire rather than a passenger-car product pressed into commercial service.
