I had snow chains for a "normal" car when I was doing mega miles. They were a pain in the arse.
I got through all of last winter on a set of wrangler AT's with no snow chains. I made it into work (bigger fool me) when others were stuck and as a regular visitor to the N York moors had no problems. We also ended up on the A1 up to Newcastle during what was regarded as one of the worst snow falls and cheerfully made it home with the Ikea mattress fastened on the roof
The winter before the T2 saw us through some heavy snow on a set of kuhmo AT's with no chains
On the basis of our antics I would suggest ( happy to be wrong) you dont bother with snow chains. :thumbs
