Modification of suggestion:
Make it 5 stamps/stickers per weekend.
Allow ANY previously stamped/stickered/used tire from that season to be ran at a HST and Majors event.
Can only run a total of 3 different stamps/stickers per weekend (not certain if this requirement is necessary).
This should cover all contingencies while enabling options later in the year for tire cycling/rotation as necessary by those who have tighter budgets.
Doing the math on this means:
Event 1 == 5 tires available to use
Event 2 == 10 tires available to use, two stickers possible (E1 & E2); can swap in one of 10 tires in the event of a tire failure (slice, blowout, flat spot)
Event 3 == 15 tires available to use, three stickers possible (E1-E3); can swap in one of 15 tires
Event 4 == 20 tires available to use, four stickers possible (E1-E4; E1 & E2 tires possibly still being usable)
Event 4 == 25 tires available to use......
This would enable the "weekend sticker contingent" to do what they need to do for pointy-end performance while supporting the "budget-friendly contingent" who happens to attend a HST/Major event.
"Weekend Sticker Contingent" - Event 4 of the season and it's a track that's hard on left side tires (LRP): sticker up then take the best tires from your previous events knowing you can only have two other stickers/stamps throughout the weekend.
"Budget-Friendly Contingent" - Event 4 of the season and it's a track that's hard on left side tires (LRP): don't sticker up and bring two sets of the best of your previously sticker/stamped tires. No need to worry about the maximum allowed stickers/stamps.
How to police and enforcement/discipline this will be the larger question but I imagine there will be plenty of eyes on sidewalls in grid.
