Does that work? Lower pressure and larger contact patch means less force squeezing the crud away. Only saving grace is a larger contact patch will be more likely to have some part on clean tarmac instead of crud, but IMO that's not going to work on unswept woodland routes with leaf fall buildup.I'm not sure about how much the tread will make a difference the cynic in me says probably not that much. Wider tyres with a larger contact patch though - absolutely - especially when you run them at a lower pressure for extra grip.
My bikes mostly run the same 37mm aka 1⅜" year round at the same 40/60psi. Tread should mean the crud only needs squeezing into the nearest groove, rather than clear of the contact patch on slicks.
