GT Radial Champiro UHP1 Tire Review & Rating

The Champiro UHP1 from GT Radial is designed as an ultra-high performance tire for summer driving use. Engineered for drivers of sport coupes and luxury sedans, the UHP1 is all about delivering more powerful cornering, faster braking and increased traction on wet or dry pavement.

A high performance silica tread compound with larger shoulder blocks provides solid dry or wet traction. It also enhances cornering abilities that you would normally expect to find only on tires costing much more. Reviews from drivers speak highly of how well this tire grips the corners and how stable it is at higher speeds.

The tire’s continuous center rib makes the steering more responsive and crisp, while also increasing straight line stability throughout the speed range. Four circumferential grooves and numerous lateral grooves evacuate water from under the tread and reduce the risk of hydroplaning.

An optimized tread pitch sequence virtually eliminates road noise and adds more driving comfort in town or out on the open highway. Inside the tire you will find steel belted construction that provides strength and durability, as well as promoting more even tread wear. The UHP1 is available in a wide range of 15-20 inch sizes and V or W-speed ratings.


  • Excellent dry and wet traction and braking
  • Cornering grip is outstanding
  • Exceptional value and performance for a very low price


  • Treadwear has been an issue for some

Overall Thoughts

We really like the summer high-performance UHP1 for many different reasons, most notably due to its outstanding grip in the corners, as well as its traction and braking on dry or wet pavement. The tire provides excellent steering response and overall feel. Another aspect that can’t be overlooked is the lower price it carries. Comparable tires from Michelin or Bridgestone are twice the price if not more in some cases.

Make no mistake though, this model is not without its flaws. The main issue deals with treadlife. We’ve heard several drivers mentioning this in reviews on this tire. Naturally, the harder you push the tire the shorter the treadlife, but some of these problems go further than that. So this is something to keep in mind. Fortunately, with the lower cost involved it softens the impact of fewer miles a bit.

Overall, the UHP1 is one of the better low cost summer high-performance tires available today. No, it may not match up to a Michelin Super Sport, PS2, Continental DW or Bridgestone S-04 Pole Position among others in terms of street performance, but for the money it holds its own and is a nice option for tighter budgets.
