265/60R18 Kumho Solus KL21 110H

Eco Solus KL21 All-Season

The Kumho Solus KL21 (marketed by Kumho as the Eco Solus KL21) is an all-season touring tire built for crossovers, SUVs, and minivans, and it also shipped as original equipment on vehicles like the Kia Sorento. Its tread compound blends High Dispersible Silica (HDS) with anti-abrasion carbon black, a formulation Kumho engineered under its Low Rolling Resistance (LRR) technology to cut fuel consumption by up to 5% and reduce rubber-dust emissions versus a conventional touring compound, without giving up mile-after-mile durability backed by a 60,000-mile treadwear warranty. A symmetric tread pattern with four circumferential grooves and numerous lateral sipes clears water for confident wet-road grip, while two full-width, high-tensile steel belts spirally wrapped in nylon keep the casing stable at highway speed and under the added weight of a loaded SUV. Kumho's proprietary noise-simulation modeling tunes the tread pitch sequence for a quieter, calmer cabin on long drives. Independently UTQG-rated 500 A A for treadwear, traction, and temperature, the KL21 targets value-minded SUV and crossover owners who want predictable all-season performance and low running costs rather than ultimate winter capability — reviewers note its cold-weather grip is limited, so a dedicated winter tire is still recommended in snow country.
