It's a hard one that's for sure.
The UTQG rating is speculative given that the manufacturer nominates their own rating.
The class is definitely useful though given that it breaks up what was a huge class 3 at the Nationals.
Multiple tire suppliers looks to be the only answer for the class to continue.
Those competing in the class need to be aware though that there will be a better tire amongst the selection and that will only be shown after the class is next run.
