I am very careful when fitting the tube/tyre and had ridden several hundred miles on this wheel without problems including 70+ kmh decent. On this occasion I was decending a 17% hill with a strong tailwind. The lack of air braking necessitated fairly heavy use of the brakes= heating of the rim= failure of latex tube. The tire is unblemished.
In retrospect the pressure was slightly higher than optimal and probably contributed to a 'perfect storm' scenario. ..........
Three problems I've had. First, I ran the new Vittoria Corsa G+ on carbon rims with latex tubes. The Corsas's seemed to trap a lot of extra heat under heavy braking. Stopped at the bottom of a hill to wait for friends and had a blowout right there. Tire was so hot It almost burned me. Switched to GP4000sii and solved the heat issue. Why? No idea but the GP combo was noticeably cooler to the touch. Latex hates heat.
Second, during the hot summer I bought several tubes that had failures, not blow-outs. I checked and they shipped through Phoenix, AZ. I think they sat in high heat for a long time. My solution - buy tubes in winter/early spring.
Third, I had to change my rim strips more often because they were pressing down into the holes in the rim, getting sharper and creating scuffing. Solved this by keeping pressure under 120 psi and changing rim strips every 5 months. Rim strips are very important with latex. FYI in a tubular, the latex tube is better padded/protected.
Hope this helps!
