The truth is if you have AWD and its working it is more than likely poor tires in the snow/ice.
I have to agree…It’s the tires. My 4runner came with Dunlap OEM tires…that were cr*p in the snow. Switched to Cooper Discover ATR…all the difference in the world. With the Dunlaps I had to switch to 4wd with the slightest bit of snow and incline. Now I rarely switch to 4wd…only in the deep stuff or a good incline.
