I hope that was a cheap tyre Wally
Back to your circuit handling.... Have you tried measuring your tyre temps after some hot laps? Infrared temp guns are really cheap now and by checking the temps at the inside, outside & middle of the tread you can figure out how the tyre is hitting the road in the bends. If you can find a handling pad to run constant circles until the front tyres start to go off (overheat) you could learn a lot.
