Tyre registration in karting: why and how
A tyre rule only works if you can check that the handed-out set was used. How to organise that without scrutineering taking an hour.

Why register
Many clubs limit the number of tyre sets per weekend to keep costs for drivers in check. Without registration that rule cannot be enforced: anyone with a spare set in the van can use it unnoticed. Registration makes the rule fair for everyone.
At hand-out
Every tyre has a barcode or serial number. At hand-out, record which numbers belong to which driver. Do it the moment the driver takes the set, not afterwards from a list. Scan the code, link it to the race number, done.
At scrutineering
After the final, the scrutineer checks the tyres of the top three, or of a random selection. They scan the tyres on the kart and see immediately whether the numbers match what was handed out. That takes half a minute per kart.
What to do on a mismatch
Lay down in the regulations beforehand what the penalty is for a wrong set: disqualification for the session is common. Race control applies the penalty, the result is recalculated and the driver sees the reason.
In Evenyo
Scanning is done with the officials app. At hand-out you link the tyres to the driver, at scrutineering you scan them again. A mismatch is visible right away, and a penalty from race control goes straight into results and standings.
