I saw a mention of these tires on the tire thread, but I think a lot of people will miss it if it's isolated to that thread.
I often ride off the pavement onto rough roads -- sometimes very rough -- on my DL1000. So for me, the quest for the perfect dual-sport tire -- good for a long haul on the highway, and good on dirt or rough roughs -- has continued unabated.
Just to get it out of the way, I can't make myself go the Continental TKC 80 route. Just seems like a long slab-riding stretch would vibrate you to jelly, and would wear down the tire more than is acceptable.
I pretty much decided by looks alone that the Heidenau K60 is as close to a 50% street/50% dirt tire as you can get. However, availability in the correct size and TREMENDOUS COST have prevented me from trying them.
Next in line for me was the Shinko 705 radial. Not because it was that close to the Heidenau tread pattern -- it's not, it's more street oriented than the Heidi, perhaps 75% street/25% dirt -- but because it looks far better than the stock Trailwings and is CHEAP. For cheap, I can lose some dirt capability.
I had decided to blow the dough for a K60 front ($150) and a 705 rear (about $90) when I came across the Fullbore Adventure-Touring radial tire.
Full Bore Tires - Adventure Touring
These tires cost the same as the Shinko 705's in V-Strom size, are made in the same factory as the Shinko 705's, but differ from the 705's in exactly the way I wanted -- the same way that makes the Heidenau K60 better than the 705. That is, the gaps between the tread blocks on the Fullbore Adventure-Touring tires are slightly wider than the 705 gaps.
This makes the Fullbores look more like a 70% street/30% dirt tire, perhaps even more capable in the dirt than that.
So I ordered a front and rear for my 1K. If anyone else takes the plunge -- or already has more experience with this tire -- please let us know. For my part, I'll be telling you what I think when I get some miles on these things.
