They were quicker, so by allowing them the handful who'd first use them would cause the rest to follow or literally drop several finals (or stop attending). So to allow them is forcing an unofficial control tyre, forcing the spending of money. As it is we can choose to use new rubber tyres (yes, expensive), or use worn tyres leftover from elsewhere.

Simon was told he couldn't use foam tyres at Southport too, so im told. Not sure of it is relevant. #justsaying

On the subject of part worns, ive found them to be more consistent than new. New tyres have taken atleast 1 round to 'come-in'. I also know many racers will use tyres at Worksop, then re-use them here for that reason, so costing £0 to use rubber tyres.
