tufo tape - tire seems to "float" when braking....(7 posts)

tufo tape - tire seems to "float" when braking....slomo

...for extended periods, while descending. i decided to stop and check things out. i was acutally able to lift the front tire about 5mm off the rim! scared the pie out of me! needless to say, i proceeded with much caution for the rest of the descent. it appears that the heat softened the glue/tape to transform it into chewing gum consistency giving me "squishy" handling.

could i have been using some old tape? would age make a difference? usually when mounting with tufo tape, the glue would evenutally ooze out the sides to cover the rim edges but it didin't happen this time. not enough coverage maybe?

any thoughts?

hey DougSloan, Akirasho, anyone, has this ever happened to you?

Another reason to stick with goodold-fashioned glue......Alexx

Sounds like Tufo tape ain't any better than that cr@ppy old Velox tape (except, maybe it actually still holds when it's wet). FWIW, I've never had GOOD glue do this to me (white 'gutta' glues notwithstanding).
Glue has worked for, what, 125 years? Why switch?

I've only used it on all carbon rims, and carbon won't transfer heat (very much). Never had that problem.

i thought that carbon doesnt transfer heat as well as you did but after stopping on the descent, the rim did get hot but not like an aluminum rim

The heat from constant braking on descents is a known problem for softening the glue. This is not often a problem, but it has even been reported in the TdF on particularly hot days and tough downhills - and those guys don't ride the brakes! Another reason to go with clinchers IMO, as the heat will NOT likely overpressure a clincher enough to cause a blowout. Tandems can be another story, hence drum/disc brakes required for heavy teams and tight, long downhills.

I am using the Tufo tape between carbon rims and Tofo tires. I haven't noticed anything out of the ordinary. The glue seems to have formed small balls at the edge of the tire/rim, similar to what you describe as ooze. I thought it looked like the exposed glue (exposed since install) was drying out and contracting into small balls.

Honestly, even without glue, I can't lift an inflated tire 5mm off the rim. I'd tear those tires off to see just how much the glue was holding. If the glue seemed useless, I'd reglue more often with the tape or go back to regular old glue. How long had the tire been on there with the tape?

the tire probalby had a week of flatland riding before i took it to the hills. i would say half of the glue remained on the carbon rim and half on the tire. the glue still seemed pliable. maybe the tape is specially made for tufo tires. i just received 3 s3 lite in the mail (sdeals) and may try it on one tire. we'll see how it goes.
