Tires Kumho or Maxxis

I've gone from XR4s to DHR/DHF. If there is an increase in rolling resistance, the only place I think I notice it is when I'm on a very gentle downward slope, and I wonder if I'd accelerate due to gravity a little faster on the XR4s. On the other hand, when I'm doing steep technical climbing in the saddle, and putting down the kind of power that made the XR4 lose traction, the DHR has never spun out.

Having ridden the XR5, XR/SE4, DHF, DHR2, Dissector the XR5 is closest to the DHR2 3C EXO. If you liked the XR5 as a front, you'll get along really well with the DHR2.

Looks like the dhr2/aggressor would be the closest match looking at the tread and tread size. You could go with the slightly slower (contentious claim on here) but more common front dhf/aggressor. I prefer the dhr2 over the dhf but giving the assegai a try once trails are opened here.

Edit: I run a DHF/Dissector combo, grippy in the front, speedier but still grippy in the rear.

I've put a couple hundred K's on mine and so far I love them. Great for street, gravel, dry dirt. The only issue I've had is the occasional wet mud on a trail. These get real squirmy in wet corners but I can't fault the tire, that's not what they're designed for.

I have a set of Kumho Crugens on one of my cars, I like them so far (just installed in October, and we do get winter).

I switched from the momentums to the grifters and am glad I did.

I bought a Trek Fuel EX this year, which comes with XR4 tires. I switched to Maxxis DHR/DHF after a month, and the improvement in grip is very noticeable. On technical climbs, its pretty easy for me to lose traction with the XR4 when I'm putting a lot of power down on a steep section. With the Maxxis tires on those same climbs, I never spin out. On the other hand, the rolling resistance is higher.

The Kumho's aren't that bad in noise, until you get to the halfway point, then it starts to get noisy.

If the DHFs are hard to mount on a given rim, particularly Stans, wait till you try a Maxxis Ikon. One of the hardest tyres I've ever installed.
