be careful in the corners for about a hundred miles or so
Put your bike up on a stand, start it and put it in first gear to get the back wheel moving. Grab a wad of brillo and scrub out the edges. Wont be hard considering the wheel is moving. Turn the bike off, set it down, restart and burn off the center. VIOLA! You have a tire that should be ready to go. I am NOT saying get deep in to corners yet, let the tire cycle warm a couple fo times. But this will cut out the slippage you get on a shinny.
The releasing agent (so the tire can be removed from the mold) used during the manufacturing of the tire is what can make it slippery for the first few miles. After the shiney surface is gone you will have a nice and grippy tire.
Do you really do this? I have had 2 sets of Pilot Road 2's and my normal break in procedures were just fine. I take it easy during straight aways for about 20 miles and gradually get the bike leaned over into turns after that. Each time is just a bit more until I feel that the tires are good to go.
I love the Pilot Road 2's. They are a perfect tire for my situation. I commute 120 miles round trip to work and ride twisties in the mountains on the weekend. They have not had me second guessing in any kind of weather or situation.
The tire molds are now made with a teflon coating that requires no release agent on the tread. I'm not sure about the off brand tires like Shinko but all the major manufacturer such as Michelin, Dunlop, Pirelli and Bridgestone all use teflon coated molds.
We put new tires on and their first lap around the track is WOT! No issues!
