Yeah (this comes up a lot do a search). Some DH racers run it up front. Compared to the DHF it has better braking, slightly faster rolling, and less of a transition zone between the center and side knobs.
 
Picard, only you can determine if a certain tire is right for you. Myself, I don’t care for the DHR2 as a front or rear tire.
 
Square casing profile makes the DHR II a sketchy tire as front.... especially on loose-over-hardpack. I have seen washout occur so fast, you are still holding bars....when you go down.

I've experienced this firsthand... this is WHY you trim it Picard. If you don't, you might as well just run a DHF and save some skin.

Have FUN!

why did you trimmed it?

Trimming opens up the side channel. This allows the side knobs to really bite. They are actually a bit bigger than the DHF, and a trimmed DHR2 will hold its own or even out corner a DHF while providing better braking. Trimming also takes away the sketch in moderate angle loose over corners, as it removes the ramping effect the very outer edge of the block provides. This lifting action takes some of the pressure off of the outer block, and a sliding you will go especially if you're in the marbles.

For trimming you only trim the one set of wide horizontally siped braking blocks, and only a small amount. You want to bring them in line or just slightly wider than the other blocks, but be careful not too take too much, there is a sweet spot. Only really applicable to the front IMO.

The DHR2 isn't an especially square tire. Lots of racers run them in the front without trimming.
You're missing the point... it's not the overall profile. The larger horizontal center knobs on the DHR2 flatten out the center tread more and this is exactly why the DHR2 rolls better than the DHF. It's also why it washes out on loose over hard when really pushed as well as on wet roots and rocks. On hardpack knock yourself out. Anything else... not so much. Apparently the tire trimming phobia is real.

Actually the rear DHR2 will wash just as fast on wet roots and rocks. Another forum member mentioned he and his buddies cut a vertical sipe in the center of the horizontal knobs and it worked much better in the wet which I don't doubt. Gonna try it on mine...

I don't like the trim out back, I prefer the braking bite over the slightly better carving.
Have not tried siping the block, but have thought about it a few times.

And yes, I really don't know why people are so scared to do a little trimming or siping. If you don't like the tire, instead of binning it, think about what you don't' like, and if it can be helped with a bit of cutting.
