Just to be clear, I'm not bashing Conti. I've used them for many years and have never had a problem, no cupping either. I'm at 175lbs and fairly OCD about tire pressure. I do ride in heat. In South Texas it's extremely hot all summer and going west is no better until we're north of Santa Fe or so. I had Michelins installed because the Conti RA3s were not in stock, and I needed new shoes for a ride to Calgary next month.
