Please note the updated Tyre Regulations effective from 1st January 2023, contained in the link on the original post.

The definition of a 'Retro' car has been clarified.

Competitors in any doubt about the regulations should contact myself or the relevant CoC of the event in question.

Note - The 2023 MSA ‘blue book’ with the applicable tyre lists should be out very soon. The tyre list in the above link is 2022 and presumably not applicable for 2023.

The 2023 MSA Blue Book and tyre lists were published today, see page 212 of below link.

For the avoidance of doubt and for clarity to all - can someone from the committee confirm that it is in fact the 2023 tyre list that is to apply to the rule changes, not the 2022 list as linked in the bulletin?

We will confirm our regulations tomorrow evening after the Committee meets, but at this time we expect that the new 2023 list will be applicable with regard to banned tyres. This will keep us aligned with events run in Northern Ireland which was a large driver in this regulation being enforced.

Please note the Tyre Regulations have been updated to reflect the new MSUK Tyre List for 2023, including further clarifications.

Anyone in any doubt as to what tyres are now permitted on TDC events are advised to contact the CoC of the event in question.

This bulletin will also be forwarded to competitors prior to any event for the forseeable future.
