For sale I have 2 pairs of new snow socks made by Autosock. They are size 645 which will fit the standard A3 tyre size of 225/45/17 and various others - please see the autosock website to check if they will fit your vehicle - www.autosock.co.uk/autosock-snow-sock-size-guide.php. These retail at Â£65 each and in my opinion are one of the best snow socks on the market. Brand new and sealed. Â£58 including postage and packaging. Payment via bank transfer preferred.
