Yup more Cup tyres questions..!

What are the general guidelines for the lower wear limit on cups for grip on track, rears particularly.. I found I had a few too many unannounced 90-100mph oversteery moments at Silly last week, which was unusual..! 1 at bridge, which is a bad corner to get it wrong.. ! rears are pretty low, but all the tread pattern is visible, maybe 1mm all over.. is there a point where the compound changes in the tyres and the grip drops off..?

10 degree ambient on the day, I usually run 34 rear hot pressures.. but will try 32-33 next time out to bring the balance back to neutral.. I couldn't get them as hot as i would like, so maybe this was partly responsible too... wink

Can you run them down to slicks OK..? or bin them before that..?

when you see the chord they are fecked

i know the outside edges are designed to run very low by Michelin but not sure how far below wear markers they run ok.

i found it slippy at Vale Club and Copse last visit but it wasnt the tyres
