The Courser HTR Plus is an extension of the Courser HTR line featuring sizes for sport trucks and plus fitment sizes. This line is also well suited for those 20-inch orginal equipment replacements. Industry-wide, typically, the same pitch sequence is applied throughout a tire line. But the Courser HTR Plus varies the number of shoulder elements based on the tire size, which reduces noise frequency and allowing a quiet ride. A rubber rim protector extends beyond the rim flange and decreases the chance of rim damage that can occur if a tire/wheel assembly scuffs a curb.
