GT Radial Champiro UHP AS Tires
Meet the GT Radial Champiro UHP AS, an ultra-high-performance all-season tire for drivers who want sharp handling and dependable year-round traction without the luxury-brand price. Its asymmetric tread promotes stability and precise steering, and broad water channels help resist hydroplaning. Dense siping adds bite in cool, wet weather, while an optimized pitch sequence cuts road noise for a smooth, quiet ride. Whether you commute, tackle highway ramps, or head out for a weekend drive, the Champiro UHP AS delivers balanced performance and value for sport sedans and coupes.
Key Features & Specifications
An asymmetric tread teams with reinforced shoulder blocks to boost cornering stability and steering response. Wide circumferential grooves and lateral notches move water away from the contact patch to support confident wet braking. A silica-enhanced compound stays flexible as temperatures drop, and multi-sipe tread blocks add extra biting edges for variable weather. An optimized tread pitch helps minimize pattern noise for refined cabin comfort. Select sizes carry higher speed ratings for sport-tuned setups, and many include a subtle rim protector to help guard wheels from curb rash.
Performance in Real‑World Conditions
On dry pavement, the Champiro UHP AS focuses on stability and clear feedback, helped by firm shoulder blocks and a stable tread design. In rain, wide channels and lateral grooves clear water quickly, which supports confident braking and hydroplaning resistance. In cold weather, the silica-rich compound stays pliable and dense siping improves traction on chilly, wet roads. Like most UHP all-season tires, it can handle light snow with cautious driving, but for frequent deep snow or ice a dedicated winter tire is the safer choice.
Sizes, Load/Speed Ratings & Fitment
The Champiro UHP AS comes in popular performance sizes for modern sedans and coupes, spanning 17 to 20 inch diameters with V, W, or Y speed ratings depending on size. Popular choices include 215/55r17, 235/45r18, and 245/45r19, and select sizes support staggered setups. Always confirm the correct size, load index, and speed rating on your driver-side door-jamb label or in the owner's manual. If you are changing wheel diameter or OE sizing, consult a tire professional to verify overall diameter, clearance, and TPMS compatibility before you buy.
Popular sizes for everyday sporty driving
Go-to sizes include 215/55r17 for many midsize sedans, 235/45r18 for sport sedans and coupes, and 245/45r19 for higher-performance trims. Some drivers also choose 245/45r20 for appearance or factory performance packages. Availability, load index, and speed rating vary by size, so confirm OE specs and discuss any changes with your installer before ordering.
Price, Value & Warranty
The Champiro UHP AS delivers UHP all-season capability at a compelling price, making it a smart upgrade for drivers who want sharper handling without overspending. Pricing varies by size, load and speed rating, and region. GT Radial backs its passenger tires with a limited manufacturer warranty, with mileage coverage and terms that may vary by size and rating. For maximum value, schedule an alignment with your new set, keep pressures at the vehicle placard, and rotate on time to protect ride quality, tread life, and warranty eligibility.
Customer Reviews & What Drivers Say
Drivers often praise the Champiro UHP AS for confident wet-road manners, a quiet highway ride, and balanced steering in daily use. Many find it feels sportier than a touring tire while still staying comfortable. Value for money comes up frequently, especially in common sizes. As with most UHP all-season options, deep-winter traction is limited compared with a dedicated snow tire, and regular rotation and alignment help maintain even wear and on-center stability.
Champiro UHP AS vs. Other UHP All‑Season Tires
Compared with established UHP all-season choices like Michelin Pilot Sport All Season 4, Continental ExtremeContact DWS 06 Plus, Pirelli P Zero All Season, and Yokohama ADVAN Sport A/S+, the Champiro UHP AS usually competes on price while delivering everyday sporty handling and wet-road reassurance. Premium rivals may offer finer steering feel or broader size coverage in some applications. The Champiro UHP AS stands out for value, comfort, and solid all-season versatility. The best pick depends on your priorities, whether that is outright performance, ride comfort, winter capability, budget, or a balance of all four.
Buying, Installation & Maintenance Tips
Before you buy, confirm your OE size, load index, and speed rating from the door-jamb label. If you are changing wheel size or setup, verify overall diameter and clearance. During installation, request new valve stems or TPMS service, and have the wheels torqued to spec, then follow up with a four-wheel alignment to protect handling and tread life. Maintain pressures to the vehicle placard, rotate every 5,000 to 7,500 miles or as your manual recommends, and inspect tread depth and wear patterns to keep the Champiro UHP AS performing at its best.
