Does anyone know how much tread is left after the little 'holes' on the outter edge of the tires are worn through/gone? I have 6 track days on those tires plus lots (9 months of approx 2x/week) of street driving on them.

Anyone think they'll last another track day or do I need to bring some black duct tape to cover the chords I'll soon be seeing?? : - )

I know it's not a ton of info but I'm sure someone's used these and chorded them and knows of what I speak.

Thanks much,
Phil

IIRC: The ‘little holes’ serve as the TWI for the big tread blocks. That should mean that when the holes are gone, you are down to the Tread Wear Indicator – maybe 2/32”.

AU N EGL

R and DOT R compounds are rated on Heat cycles not tread ware. When the little holes are gone, time to toss the tire.
