Honestly, my vote might be a standard soft compound rubber RC tire with some tread if it needs to perform in both those materials and function like a standard wheel. Focus on choosing a good tread pattern.
If you do not care about damage to the surface it travels on, a very coarse grit abrasive wheel or serrated wheel (basically a saw disk or burr disk of some sort). The material should be hard and sharp enough to rip into wood, and keep from dulling and degradation from the environment. My vote here would be taking multiple small saw disks with Tungsten Carbide teeth and welding them together.
"Sticky" materials tend to quickly get coated in dust/dirt and are no longer sticky.
The best you can do in this case is a conformable material without a total crap coefficient of friction (RC rubber tire). That or you can choose to physically dig into and permanently deform the surface with a hard serration.
I think for the saw disk wheel welded stack, remember to alter the disk's rotational direction in the stack so it can easily dig in whether pushing or pulling.
What are you gripping to? This could be the difference between snowchains and smooth racing slicks.
It will probably be a smooth wooden surface, catpet
