I recently corresponded with Martyn Halliday of the HSTA regarding tyres.
The control tyre for the Historic class, both the 750 and 1172 are Blockley 4.50/5.00 x 18.
I quote from his email;
”Our control tyre has very stiff side walls and basic block tread. We run then at 5psi and they do not flex much but last for ever.
It was chosen as we did not want a very grippy tyre. This means we are not putting such great strain on old transmissions and we can have more gentle sections.”
The Blockley and the Longstones are similar tread pattern.
