Why do people say to wait 100 miles before pushing tires hard but when people put on brand new tires at the track they are good to go after a few laps?
Rubber products generally have a mold release agent still on them. Depending on what kind, it can be very slick, even waxy. Careful use and weaving as described will get most of it off. I prefer to scrub down new tires with a Scotchbrite pad in warm water and dish detergent. If I just change a rear, I may use the easy way. Spin the rear tire in sand(low rpm) while rocking from side to side. I can't tell you about race tires, they don't fit my moped.
It only takes a few curves to break in a new set of tires. Ride it slow for a little bit to warm the tire up a bit. Then find a curvy road and start by going thru the corners with only a small lean angle. Keep leaning the bike a little farther every corner. Remember both sides of the tire need to be scrubbed before you let it all loose. Two weeks ago I broke in a new set of tires in about 15 miles. They still have about 1/8 inch of chicken stripes left but the peg feelers touch before I get down any lower since I move my butt off the seat when riding aggressively. Hope this is the info you were looking for, just remember to ease into it little by little until they are ready to go.
Race tyres are NOTHING like street tyres. They are far softer, and as a result, the shiny, smooth surface of the tread wears off very quickly. They also get much of their traction from the tyre heating up when used and becoming more pliable - road tyres don't do this to any significant extent. Try working a road tyre too hard too soon, and you'll feel like you're riding on ice. Good luck!
