These work awesome as a front or rear tire. The other great thing is that not only do they have different widths, but different rubber densities for tweakability. I'm running a 2.35 up front and a 2.1 in the rear with a slightly harder compound. 2.1 sheds mud really well but mind you it is a SMALL 2.1 if not a 1.9-2.0. Still if you're riding a soft-tail, just run a high pressure and the pinching won't be an issue. I haven't yet found a condition that doesn't suit these. I can climb out of saddle on slick hardpack and she still hooks up. A heavier tire that's worth every penny!
