I bought some Conti Supersonics in the 650x20 size for my Rocketwing. These were going to be my race tires for 20k time-trials at Fiesta Island which is flat with a good smooth surface.
Well, I've had 2 blowouts already. The front tire blew out right after I aired it up with a CO2 cartridge. The other tire blew out after being ridden a couple miles as a back tire. It had been inflated to 160psi.
Continental says the tire can be inflated to 170psi so I'm wondering why they blew. Maybe I'm too heavy at 205lbs to use one as a back tire?
I'm putting my Michelin Ironman 650x23 tires back on for my time-trial tomorrow!
Your feedback appreciated!
