Can someone recommend one of these tires for me. DMR Moto R 26x2.20 or DMR Digger 26x2.35 or The Maxis Holy Roller 26x240. I have a feeling I really can't go wrong with either Tire, but who knows. I would like something to keep me rolling thru the doubles since I'm still working on my pumping skills plus provide a little grip around the berms. I currently have Nokian NBX 26x2.3 F/R. and they feel like they're slowing me down a bit. I'd appreciate any advice. Thanks.
