<h2>Kumho Ecsta STX KL12 305/50R20 120V</h2><p><strong>OVERVIEW</strong></p><p>The Kumho Ecsta STX KL12 is an ultra-high-performance all-season tire that's designed for use on CUVs, SUVs, and light trucks and offers excellent traction on wet roads. Wide grooves reduce hydroplaning by forcing water away from the tread, and the optimized tread blocks of Ecsta STX KL 12 reduces road noise for a quiet and comfortable ride. A large contact patch puts more rubber on the road to improve steering response, and the Ecsta STX KL12 also utilizes a low sidewall that protects the tire from curb and wheel damage.</p>
