Woke up this morning to head off to a race and my front Tufo HICC lite was flat. Squeezed in a third of a tufo sealant tube, pumped it up and gave it a spin. A little white dot appeared pretty quick showing me the pinhole but it sealed up in a couple of seconds and I went on to have a great race. It was a really twisty course so putting on a spare that close to the race would have been too risky. Ended up having a great race and winning. Anyways, I think I’m sticking with the Tufos regardless of the whole rolling resistance thing. I’m not a big fan of the S3-lites though unless it’s a drag race type course without many turns. The HICC lite has way more grip and is about the same weight as an S3. I just mention this as I think most people by the S3-lites and don’t know about the HICC-lites. I am tempted to try out conti competitions again though…
TUFO tire sealant is good. It bridges the gap between fluid and solid.
How do you get the sealant into a tire already glued to a race wheel? Do you inject it through the valve extender?
I was going to try the S33 pro tubular clinchers , as most of the spec’s seem the same , just a higher weight and lower thread count compared to their higher end tires. I normally end up with a flat ,when I play the gram game on thin tubes & tires . But whats the limit on that sealant , three holes - your out / no unstitching of the case for repair I guess ?
I had vittoria extendors, the type where they actually relocate the valve to the end of the extender. You unscrew the valve from the tire, screw on the extender and screw the valve into the end of the extender. If I had more time I would have taken out the valve but I was trying to get to the race so I just squeezed right in through the valve. the valve may be shot now but I’ll just steal one from an old tube.
don’t know the limit, basically it would be limited by hole size and if the hole is somewhere on the casing that the sealant would flow into (ie on the sidewall you’d have to hold the tire sideways to seal it). You can’t unstitch a tufo anyways, as the tube is vulcanized to the tire casing, this is why the sealant can be used.
