Nokian Tyres Inc. says the new Rotiiva AT (All Terrain) all-season tire grips effectively both on and off the road. This sturdy, special tire guarantees optimal performance without compromising safety or driving comfort. Available in spring of 2012, the Rotiiva AT completes the Nokian’s SUV and 4x4 range. It will be available in 26 SUV and light truck sizes ranging from 15" to 20". Nokian says the aggressive tread pattern of the new product, and especially its wide, polished grooves, maximize grip and handling in rapidly changing summer conditions. Thanks to a unique tread pattern, the tire also cleans easily and runs effortlessly on a soft platform.
