That's exactly what I ran a few weeks ago, worked well.I wonder what a DHF ST and a Higheroller II 3c combo would be like at Whistler? Im gonna go with the ST Minion DHF/DHR for the trip. You know I love those Specialized Butchers, but they are wearing fast, but probably due to the terrain @ Aly and the rape they take on tanaka. Im gonna take them for the trip for backups.
You are correct about the compound configuration (70a base layer, 42a outer center layer, 40a outer shoulder layer), however the 70a base layer flows up into the knobs less than 1/3 the total height. Most every rider would replace the tire before it wears down to the harder base layer.They do wear quicker but like mentioned above the 3c have a coat of 42a on (I think) a 70a hard compound for the center, then 40a on the side over 70a knobs. Once the softer compounds have worn off the knobs, you are left with quick a different feeling tire as you're running on 70a!
So if you have $$ to buy new tires as soon as the soft stuff is gone then they might be good, other wise the ST's, yeah the tread might be half gone, but at least its still the same rubber!
I'm not sure I follow what you're saying. The 42a outer center compound of the 3C version IS the SuperTacky compound. So the center of the a SuperTacky tire will wear at the same rate as a 3C DH tire.3cs have 42a exterior compound. that will wear off in 3 days. then you'll have half ass tread knobs. the 60a st compound will suprisingly work better for longer than the 3c. I just roasted the top two layers off a 3c while the st still looks new! I have several cat 1 wins this year, I would not buy another 3c tire for a rear. I ran the rear as 3c and the front as st. I won't pay for another 3c unless I only use it in race runs.
I totally agree... the 3c DHFs I've ran have worn out due to the sideknobs wearing near the inside base of the knob, once they wear enough the sideknobs don't hold well, they start tearing, and the tire is toast... but I've never wore out the tire by actually wearing down the sideknobs... they tear off far before they wear down that much. The rear tire sees significant breaking knob wear, but I usually don't run 3c tires on the rear.You are correct about the compound configuration (70a base layer, 42a outer center layer, 40a outer shoulder layer), however the 70a base layer flows up into the knobs less than 1/3 the total height.
