Four 275/40-17 RA1 rain tires. Were on track twice.. Once on Michael's CMC car and the second time on my AI car and was the only time I ever beat Mike Patterson (at TWS).
No visible tread is gone except one tire has a slight "triangle burn" where Michael locked up in the rain slightly. I wouldn't call it a flat spot at all.

Date codes are:
1112 (11th week of 2012)
1213 (12th week of 2013)
1213 (12th week of 2013)
1313 (13th week of 2013)

Can either pickup in Richardson or can deliver to Hallett. I'm loaded down for COTA already with "deliveries"..

$300 for the set of four.
