Good point about lower tire pressure, I forgot to mention that. I'm running 12-13 psi these (Desser 850 x 6 tundra tires).
Sorry the picture of my tire isn't that good, but I think you get the idea of painting a slip mark.

Maybe too obvious, but hasn't been mentioned. Worth patching and keeping the tube as a spare in your travel kit or in your shop.
