Outdoor rubber tyre additive

[colin367]

Whats the current rule regarding outdoor racing at bigger events with additive ?
Is it down to the specific track or is there a certain list/rule for rubber tyre racing on an outdoor circuit ?

Cheers

Hi, yes i'm thinking on road touring cars etc

There's no list, the only rules are that it can't contain oil of wintergreen and can't mark or damage the track surface.

MR33 is a good starting point at most tracks.
