It's looking more and more likely that my trip to the Alps neat year is happening. As we'll be there in January, I'd like to have some snow chains alongside the new tyres, just in case. Can anyone recommend any for 20" wheels?

I have Thule / Konig K77´s

Hard to review really as I've had 2 sets (4 chains) for probably 10 or more years and never had to put them on in anger, though they do spend the entire winter in the boot.....

I live in a ski resort and have Conti winter tyres which are excellent IMHO - hence not actually ever needing the chains despite driving on some fairly bad roads over the years with most other people not being able to continue without chains.

The K77´s have nothing around the back which is where the clearance problems are with regular chains. It also means they are way easier to fit, though I've only ever practiced in a warm & dry garage.

They are also adjustable - IIRC there are 5 removable links, so they fit a range of tyre sizes, there´s a chart telling you how many to remove for your specific tyre size. Therefore they should be useable on whatever my next purchase is if it´s a similar size to a FFRR.

If your near Tonbridge, go and see these people. Really helpful, bought a few sets of chains from them over the years.

Thanks gents. Yes, Tonbridge is pretty close to me so they sound like a great place to start!
