I can tell you that it sucks in New England terrain.. In the dry, it's decent.. Anything wet, muddy, rocky, rooty, or sandy - they plain out suck. Especially the front tire - it's horrible in anything other than dry soft dirt.

ANd they cost like twice as much as the ones that I almost exclusively use - the Kenda Trakmaster II's.

 

theyr good on the street and theyr good in dirt

 

Dirt with some moisture in it. Not WET, but, not powdery dust like we ride in 95% of the time out here.

The D606 tends to blister in hot conditions, and seems more sensitive to proper pressure. That's not a problem if you are always off-road in the desert, but, I've seen countless people have center chunks melting off of them if they don't air back up when they get on hot pavement with them, me included.

What they DID do well is progressively slip through corners on pavement. They don't lose grip as suddenly as some others, and they don't seem to squirrel-around as much as the Kenda 270's when cornering hard on the road.
Off-road, the softer-carcassed Kenda 270 gives me a better bite than the tougher-carcassed D606, while absorbing hidden rock hits better than the D606. I had to run the D606 with much lower pressure than I like in order to get it to feel anywhere near as compliant as the K 270's.

I'll try a Pirelli DOT-rated Trials tire on the rear next, though. I don't think the K 270's are the best thing available, I'm just comparing them to the D606 in my desert riding experience.

 

uhhhhh no, the knobbier (is that a word?) a tire is the faster it wears. Less rubber on the road means that what does make contact has to work harder and bear the brunt of the weight, plus ***** flex which cause even faster wear. But it really doesn't matter what we use, because we are having too much fun to care!!!

 

I always had good luck with the D606 on the rear, never tried one on the front. I have, in the last year or so, gone to full MX tires because I have gone to riding mostly dirt lately, and I don't want to compromise on traction.

hell's ya! well the maxxis IT tires i use are for desert and they are really hard so that way they last atleast as long as a 606, 606's are junk after they wear down a little bit to where a knobbie still hooks up well. Just my expierience though. i would go with the k760 if i wanted a good street legal knobbie. They last ok, hook up good, and are cheap! =) i ride in clay and rocky conditions which are REALLY slippery when wet lol
