The shop where I have my tires changed used to have me sign a paper saying I was aware that new tires can be a hazard because of the mold release compound. They didn't last time, but who knows why not. They did make sure to remind me to ride them in before expecting best grip.

For me, it's not so much not riding aggressively, but being defensive enough to not need a hard maneuver. Then, ease into the corners, until the chicken strips slowly narrow.

I don't think tires are made with mold release anymore, but they still have a slick surface from the mold - and may have a coating for storage, as well. Try to get a tire maker to 'fess up on this one, though.

UPDATE: I did some searching around, and found that mold release is still used, but it's not the old greasy stuff from days gone by. Many makers of it advertise how their stuff stays on the mold, and may be used for a day's production without reapplication, implying not much sticks to the tire, if any. Modern molds are more highly polished than years ago, too, which may be why the tires don't grip until worn a bit, but 100 miles may be more than needed. The exception is when the tires come with that grayish-white gunk on them (which I've only seen on auto tires, so far); I think that keeps the surface from ageing in storage, but I haven't found any comments on it, except it is nasty looking.

Not sure if anyone follows rugby. The world cup is on now. RWC 2019 will find it on youtube.
Some of the foreign announcers are refreshing to listen to. But just rugby talk. Referring to the player with number 1 on his back. Japan's most capped hooker. Anyone care to interpret?

Being capped means being given an award; hooker is one of the player positions on the team.

I guess the meaning of 'capped' depends on where one plays; in some leagues, you are awarded a cap for quality of play. Describing a player as 'most capped', I think, means just that. I refrained from listing the definition of hooker, feeling team position was adequate, like calling an American football player a quarterback. More detail was superfluous, IMO.
