Higher safety on wet roads
For additional safety, Aqua Channel surface sipes quickly evacuates the water film from the tread pattern as they touch the road. This provides the tyre greater water evacuation capability.
On wet highways, the middle of the UltraContact UC6 225/45 R18 is at maximum risk from aquaplaning. To further decrease this risk, particularly developed Aqua Drainage elements are placed to quickly thrust water through a tube structure into the tread grooves.
Shorter braking distances
The chamfered angle of the UltraContact UC6 225/45 R18 Diamond Edge in the pattern increases the contact area of the pattern to dispense the braking forces more evenly while braking.
Without this chamfer, the tread block changes and misses some of its contact with the road. In wet situations, the Diamond Edge performs as a wiper that dissipates the water film away from the tread blocks for shorter braking distance.
Adaptive superb grip level and long mileage
The new adaptive Diamond Blend Compound contains two polymer types:
The short grip-polymers of UltraContact UC6 225/45 R18 are triggered when the vehicle is driving over corners or when braking. This energy enables high grip and short braking distances by transforming itself into heat. The long mileage-polymers are entwined and therefore powerfully connected to each other, which guarantees an efficient and high mileage, thus increasing performance.
