GT Radial 100A2025 Champiro UHP AS 225/50ZR18 95W Ultra High Performance All-Season Tire

The GT Radial Champiro UHP AS (100A2025) is an ultra-high performance all-season tire engineered for performance coupes, sedans, and sport-oriented passenger vehicles. Delivering confident capability across dry, wet, and light snow conditions, it combines spirited handling with everyday practicality and is backed by a 45,000-mile tread life warranty.

At the heart of the Champiro UHP AS is an advanced Nanometer Silica tread compound that improves grip across varying temperatures, reduces rolling resistance for better fuel efficiency, and helps prevent heat build-up — extending the tire's overall service life.

Key Features:

• Nanometer Silica Tread Compound — Enhances wet and dry grip while reducing rolling resistance for improved fuel economy
• Full Depth Sipes — Create additional biting edges throughout the full life of the tire for consistent all-season traction
• Four Wide Circumferential Grooves — Efficiently channel water and slush away from the contact patch, reducing hydroplaning risk in wet conditions
• Center Rib Design — Promotes straight-line stability and delivers precise, responsive steering feel
• Large Shoulder Blocks — Increase tread rigidity for enhanced cornering grip and handling control
• Variable Pitch Technology — Optimizes tread element sequencing to minimize road noise for a quieter, more comfortable ride
• Rim Protector — Raised sidewall bead helps shield alloy and chrome wheels from curb and parking damage

The Champiro UHP AS carries a Standard Load (SL) rating with a load index of 95 and a W speed rating, making it well-suited for spirited driving demands. Whether navigating rain-soaked highways or light winter precipitation, this tire delivers the confidence and control performance drivers expect — season after season.
