The GT Radial Champiro UHP A/S (100A2012) is an ultra-high performance all-season tire engineered for drivers who demand confident handling year-round without sacrificing wear life. Sized 235/40ZR18 with a 95Y XL service description, this tire delivers exceptional straight-line stability, cornering grip, and braking performance in both dry and wet conditions, along with reliable traction in light snow.

At its core, the Champiro UHP A/S uses an advanced Nanometer Silica tread compound that improves grip across a range of temperatures while resisting heat build-up for extended tread life. The specialized directional tread design works together with the compound to maximize contact patch performance in every season. This tire is backed by a 45,000-mile treadwear warranty.

Key Features:

• Nanometer Silica Tread Compound – Improves all-season grip, optimizes rubber flexibility in varying temperatures, and extends wear life
• Full-Depth Sipes – Create biting edges throughout the full life of the tire for consistent all-season traction
• Four Wide Circumferential Grooves – V-shaped directional groove placement disperses water and slush from the contact patch to reduce hydroplaning and enhance wet performance
• Center Rib Design – Delivers precise straight-line stability and crisp, responsive steering feel
• Variable Pitch Tread Pattern – Minimizes road noise by canceling soundwaves generated between the tread and road surface for a quieter ride
• Rim Protector – Raised edge along the sidewall guards wheels against curb damage
