I have a 2012 LR4. Currently have Bridgestone Dueler h/l alenza 255/55-19 on car. Taking a trip to the mountains this coming weekend and it usually is not a problem, but there is some snow in the forecast and I might need chains as a backup. Time and options are limited so I am in need of something that is available on Amazon Prime shipping so I can get it in time.

Here are my questions:
1. If I have one set of chains--rear or front? Does ascending or descending change that?
2. How much clearance is there for the chains?
3. Which chains would you suggest?

The best options I saw on Amazon are either the Thule XG12 which need 12mm clearance or Security Chain Company options--The only one in stock is z579.

Need to get on this ASAP. Looking for any advice.

 

Atlantic British has a sale on chains. Check local laws on 4X4s and which axle, I do front.
