While studded tires don't have much use in the UK, for parts of the Nordic countries they are essential for safe mobility.
To find out which of the latest studded winter tires are worth fitting, Swedish magazine Vi Bilagare have tested seven studded winter tires in 225/50 R17, and included a studless nordic friction winter tire as a comparison.
Even if you don't live in an area that needs such an extreme winter tire, the difference in performance between the latest studded and studless winter tires is an interesting demonstration.
The main novelty of the test came from the new Continental IceContact 3, which is the first tire to use rubberised flexstud spikes. These studs claim to offer reduced road wear, while improving traction on ice.
Dry
During dry braking testing, the studless friction Continental VikingContact led the way with a significant gap to the best studded tire, which was also a Continental.

Wet braking testing swung the balance back to the studded tires, with the studded Continental tire stopping the test vehicle in the shortest distance. The studless winter tire could only manage a mid-group performance.

Perhaps the most interesting result of the test was the ice handling, as the studless friction tire beat ALL the studded tires! This was due to the types of ice used for testing. For traction and braking testing, smooth ice was used as it replicated ice found at junctions, but for ice handling, uneven ice was used which is closer to the icy surfaces you find on the open roads.
The testers did note one extra important point. When you lose grip on the studless tire, it takes much longer to recover the grip, which means they still recommend studded tires overall, as they will provide higher manoeuvrability and safety reserves in real life useage.
