Dear fellow track rats,

I own a set of Toyo RA-1's that are getting pretty well worn. As this is my first set of these tires, I am not quite certain how far down I can run them. I've heard they can be run until they show signs of cording. The tires are now fairly bald with minimal tread still visible. I'm not sure how much life is left before the cord starts to show. Will I be able to run them for long after the tread is worn off completely?

I'm planning to drive up to Watkins Glen in a couple of weeks and I just want to feel conifident that I will get two days of track driving on these tires before they need to be replaced. Any thoughts/feedback will be appreciated.
