Trident now stocks AutoSocks. Approved by Honda, AutoSocks are cost-effective alternative to snow chains and they really do work far better than you might expect. This is because the AutoSock has a specially designed surface pattern that makes the total contact area exposed to dry friction as large as possible both under dry and wet snow or ice conditions. Hairs between and at the contact areas increase the totally exposed contact area to friction. In addition the AutoSock has a surface pattern that makes the total contact area exposed to friction sufficiently large under both soft and hard snow or ice conditions. A combination of surface pattern, strength and elasticity that make the contact points sufficiently sticky under hard snow or ice conditions.
Nat Barnes, Motoring Editor, Daily and Sunday Express, described them as:
This cheap alternative to snow chains or to winter tyres is staggeringly easy to fit. I used them while driving in the French Alps and can confirm they are absolutely superb.
