Maybe get together with the other competitors at Round 1, and see if you can present a united front for having a change made for subsequent rounds.

If you're serious about this, I would pick a tyre, probably the AKA tyre suggested because Mikey has already done the leg work with Painy. Then get a petition drawn up and take it to all the SCT drivers at the first round. If you get a sufficient portion of the field for your liking then give the petition to the Club Reps and ask for their reconsideration for Round 2.
