I expect for a serious offroad all season tire there will be available in the near future a type of tire that will be similar to what the Lunar Rover used, it will have retractable studs, paddles or rain grooves that would sense the road surface and automatically adapt. As far as ride comfort the rest would be reactive hydraulic shock dampening systems. Not to mention it can also change its profile as well.

Where I live everybody uses studded Cooper tires (Alaska) but usually the tire gets tossed after 2 or 3 years because the studs wear out.

I never liked Coopers for regular driving but they do know dirt racing.
