As other people have been saying Schwalbe with the new Trail/Pace/Vert Star compounds. I've been running Fat Alberts for almost 3 months now and they have been amazing. I use to run Conti only and Schwalbe grip much better in the wet and aren't all over the shop in sizes(Mountain Kings tiny for a 2.4 and Rubber Queens HUGE for a 2.4).
My Fat Alberts have a tread width of 63mm running tubeless at 25psi.
