We recently received close to 8"-10" of snow. This is the first time I install tire chain on my 95 Pathfinder. I only have one set of Z diamond pattern chain. People in the internet debate some pros / cons of installing chain in front and rear wheels. Upon reading it I decided to mount them in front for overall better steering control and brake control. Tonight pull out the owner manual indicated by Nissan that I should install those chains in the rear. The question is what harm have I done by mounted those chains in front wheels for the last two days? Any advises would be greatly appreciated!
