This is what the provisional rules say; 2.3.8 Use of tires a. The competitors shall only use tires listed on the allocation sheet provided by the official supplier. b. For each event, all tires must be made of the same quality and shall be strictly identical. Both of these rules would indicate that there will be an official supplier and that all tires from that brand will be to spec.
These tires rules prevent a supplier from making custom or one-off tires for a limited number of competitors. Every brand must make their approved tires available to all competitors that want to run that brand. All championships with open tire rules that I have seen have something similar.
It doesn't look like that to me since we already know Daytona has mandated the 200 to be an open tire race. But it sure seems that meeting these requirements for Michelin, BStone, Shinko, Conti, or whoever will be difficult unless they bring in factory engineers/techs to manage the event. Secondly does the "allocation will be done on a random basis" mean that MA will have staff in each tire garage to pull tires from the stack? Yikes, they are going to need a bunch of extra staff to do this as the rule is written.
About a zillion years ago I was at Daytona and NASB Sportbike qualifying was going on. Dave McGrath put on a 501 rear for qualifying and it lasted 2 laps before it chunked.
What use to be the % when CCS did the D200 ? Any other major changes from what it was ? Don't really know since my bike has been legal in both organisations... and up here in CSBK. Got an interview on a Podcast and will get asked some Daytona questions. If anyone is interested in seeing my ugly mug: Please join us tonight from 8-9pm EST.

CCS rules differences: Cutoff was 110%. But it was also a higher number of riders, I want to say in the 80's in some sessions. There was no pit lane speed limit, and you could not touch the bike when fueling was going on. You also could change tires on a red flag which means you could potentially avoid green flag tire changes.
Right. You still had to do a stop (or at least enter the pits) under green flag conditions, though. You couldn't go the whole race pitting only under red flags. It was a good rule, I thought.
Barrett Long ran a Dunlop 2662 rear for 2 laps on his 848. It was chunked after that. Maybe 4 years ago?
There used to be a 2662 rear compound. Then they renamed it 097 I believe? I brain dumped all the old numbers!
Yeah, here's me looking down from my ivory tower at someone on a 600 who made a conscious decision to ride around Daytona on a bent rim to try and salvage a 48th place finish.
