Re: Steer axle vs drive axle tire tread style (ie. Rib vs sipe or lug)

OP said he doesn't care to discuss tire brands - he is only asking opinions about tire tread design.
As a highly qualified armchair engineer, I can't see how rear dually tire tread design would make much (if any) difference in common low traction situations. With all the weight hanging on the rear axle of a diesel pusher, traction is normally gonna be pretty darn good...until it isn't. But where do large pusher motorhomes commonly get in trouble? Three conditions that I have read about (but never personally encountered).
1. Mud. Stick a diesel pusher in mud, and the tires won't matter. The tread will pack with mud, and any tire turns into a slick. Call a wrecker.
2. Sand. The only tires that help in deep soft sand are flotation style paddle tires. Anything else is useless once you get stuck. Call a wrecker.
3. Snow and ice. I suppose a special "snow and ice" tire with specific tread design and rubber compound might help. No personal experience. I'll let those who have been there comment. I prefer to sit out the storm and drink hot buttered rum.
