Wet rails may indeed even things up, but.....
I have odd angle tracks crossing our main n/s bike route, near my house. Tracks are set at an odd angle, on a curve, with a rise. Wet steel sucks. Hit them at 90.
However, I have crossed these same tracks, dry, on 23's, 25's, 28's, 32's, 37's and too many 26" wheel combos to list.
I have to be a lot more careful on the 23's than on my 2.15" Big Apples.
I have generally found the wider tires to be much more forgiving, if that is important.
On these tracks or any other road hazard/surface irregularity.
