Overview
Kumho Ecsta STX KL12 P305/40R-22
The Ecsta STX KL21 is an ultra-high-performance all-season tire designed for CUVs, SUVs, and light trucks and offers excellent traction on wet roads.
Features & Benefits
- All-season tread
- Black sidewall
- Large contact patch on the tire’s tread puts more rubber on the roads for greater steering response
- Drivers of CUVs, SUVs, and light trucks long for a tire that can provide stable handling year-round, and the Ecsta STX KL21 from Kumho was designed to do that and more. Wide grooves within the tire’s tread pattern move water away from the tire to increase traction on wet roads while reducing the likelihood of hydroplaning. The Ecsta STX KL21’s tread blocks are placed in a way that reduces road noises so that drivers consistently receive a quiet, comfortable ride, while the tire’s lower sidewall protects it and the wheel from curb damage. Thanks to its all-season capabilities, the Ecsta STX KL21 is typically used on today’s most popular CUVs, SUVs, and light trucks such as the BMW X5, Cadillac Escalade, Chevrolet Tahoe, Chrysler Pacifica, Dodge Ram, Ford F150, GMC Envoy, Mercedes ML 430, Toyota Tacoma, and Volkswagen Touareg.
