A copy of my post on a different thread.... Last Sunday I went through a minor blizzard for a 10 mile stretch on Hwy 93 to Boulder with 6-7 inches of snow on the road. All the passenger cars and a few common SUV's were running at around 5mph with their flashers on. They were all bunched together in a collective ”Oh ****" mode and struggling to get traction. My 2013 LR4 HD with the TerrainContact A/T's had no problem getting through. It was amazing! Safely passed about 15 on the way up and about 20 on the wayback to Denver. Not cocky but confident! 19inch wheels.
Great, but please be careful as well, one of the owners here living in that area hasn't had many good things to say about TerrainContacts in snow and icy conditions.
Things seem ok but sometimes it maybe hard to tell if you are really riding near the upper limit or threshold point of a tire until its too late.
TerrainContacts may perform exceptionally well in snowy/icy conditions on a subaru or other lighter AWD vehicles, but it could be that its working way harder and/or close to its limits with a heavy beast like an LR3/4, specially during braking and turning.
Not to say that they are not good in those conditions but I personally would have felt a lot better with peace of mind riding these in bad wintery conditions if it had that three peak snow mountain symbol on it.
But if you are getting good feel and feedback from your four corners in snowy/icy conditions than thats also great news. How many people/cargo were you driving your 4 with at the time? Weight maybe of relevance and importance here as far as braking and turning.
