I am curious that how much more and less ground contact we can get from the E-rated tire at different psi? Even pressure at low 30s the tire seems to work . Should I even bother to lowering down the pressure when driving in snow or sand?

I’m running at 45-46 psi, in snow everyday, no issues. 4-5 inches of snow on roads.

I put K03's on 9/30, have put over 3k miles on them. Went from Santa Fe to Montrose via 285 to 114 and the switchbacks to Gunnison and then to Montrose when all the bad weather came through in November, we got 16" at our house outside of SF. I ran the tires at 36 psi on that trip with zero issues and it went like a goat through all those snow/ice switchbacks. I saw at least 6 wrecks from Antonito, CO to Gunnison, some people are really poor drivers and visibility was pretty crappy in some stretches. The fenders/wheel wells are bad about accumulating ice/snow, as well as the running boards, had to stop in Gunnison and break the ice out because the tires were rubbing against the ice. I currently have them at 39 lbs in SF and will likely go to 42 in warmer weather. I like they way they drive and corner, overall traction has been excellent.
