GT Radial Champiro UHP1 Review & Rating
- Dry traction and braking
- Cornering grip
- Low road noise
- Stiffer ride
The GT Radial Champiro UHP1 ultra-high performance summer tire is built to deliver outstanding dry and wet traction, cornering grip and low road noise for drivers of sports cars, coupes and sedans. How well does this tire live up to these claims? We spent some time with the tire, tested it in several key areas, and found some surprisingly good results.
Overall, dry-road traction and braking stability were both extremely solid for this tire. In fact it delivers the type of dry traction you would expect from models costing much more. Braking was quick and crisp, with the tire able to effectively stop on a dime. Over the course of our tests, we didn’t lose control once.
GITI has worked hard to give the tire top-of-class traction and handling, constructing it of a high silica formula and incorporating center rib and groove designs that are built to improve both wet and dry road grip.
Wet pavement traction was equally as impressive for this tire. The Champiro UHP1 displayed an incredible amount of traction in both light and heavy rain, with a great deal of hydroplane resistance. Though there may be other tires that offer better overall performance, the UHP1 is among the better tires in its class for traction in wet conditions.
Cornering - Steering
Although it has a somewhat softer sidewall than other tires of its type, the UHP1 was still incredibly responsive while turning. When we pushed it too far, it communicated the fact almost instantly with us, and it was able to take sharp corners with ease. It never seemed to lose grip.
This is likely thanks in large part to the integrated shoulder blocks, which grant a great deal more cornering force and traction. Compared to other tires in this class, the UHP1 holds its own quite well when it comes to dry cornering and handling.
Steering was very responsive as well, though perhaps not as quick as some higher-end summer tires.
We did not test the tire in winter conditions, as it is not designed for winter use. Results would have been predictably dismal. We recommend that you use a winter tire rather than the UHP1 if you live in a cold weather climate.
Ride Comfort - Road Noise
One area where the UHP1 could be improved is with its ride comfort. It’s a bit stiff, but that’s not entirely unexpected among lower costing tires. Road noise is predictably minimal, thanks to the UHP1’s pitch variance tread design, which allows for a much quieter ride. We were actually able to communicate with others in our vehicle without having to yell when driving at higher speeds.
The Champiro UHP1 has a treadwear rating of 280, meaning you can realistically expect to get around 20-25,000 miles out of the tread. The average driver should find that the tire easily lasts them at least a few summers, while more aggressive or more spirited drivers might need to replace the tires somewhat more frequently.
It’s worth mentioning that the tread is more on the softer side, which will have an impact on their longevity in most cases.
GT Radial provides a limited tread guarantee on the UHP1. A five-year warranty on materials and workmanship is included, as is a one year guarantee on tire uniformity.
