GT Radial Champiro UHP A/S vs Ironman iMove Gen 3 A/S tires on traction
Let’s take a look at the traction performance of both tires and find out which one is better when it comes to maintaining surefootedness and gripping the surface. In our analysis, we found that both tires gave each other a tough competition, and one of them marginally surpassed the other.
Starting with the Champiro UHP A/S, the tire earns a decent 7.9 SimpleScore rating in traction and features a Nanometer silica tread compound that helps in maintaining grip and traction in dry, wet, and light wintry conditions. There are full-depth sipes that provide increased traction and grip on wet and slick surfaces, and the four wide circumferential grooves improve water evacuation for hydroplaning resistance. Additionally, the large-sized shoulders with lateral grooves and sipes also improve traction performance.
On the contrary, the iMove Gen 3 A/S competes well with the GT Radial tire and scores an 8.0 SimpleScore in traction. The tire features an asymmetric tread pattern built using an all-season compound for year-round performance. There are 3D sipes that enhance the grip and traction in wet and snowy conditions, and larger, stable blocks boost performance on dry roads. For enhanced performance in wet and light winter conditions, the tire is offered with increased siping and lateral slits.
While both tires are great on the traction front, it is the iMove Gen 3 A/S that excels by a small margin.
