Terra Speed 40mm & Hookless Rim?

Does anyone know if it’s safe to run 40mm Terra Speeds on hookless rims? Mechanic says it’s fine. Just thought I’d double check. Thanks in advance.

I’ve been running a set on Enve 3.4 ARs for the last year with no problem. I’ve put them through singletrack and crit racing and all the gravel in between.

Firstly, you really have to trust your mechanic . Or find another one. The other thing that’s cool is Google.

That said, it’s always important to check the manufacturer however in Continental’s case, their tubeless tires are hookless unless printed otherwise (see previous GP5000 sidewalls as an example).

Finally, be mindful of tire pressure recommendations. Exceeding 130% of max pressure recommended is a guarantee tire blow off.

Trust me. If I found a definitive answer on google I wouldn’t be posting here. I even wrote to continental. Got no response.

So you’re saying they’re hookless compatible? You’d think both Enve and Giant would add them to their lists.

I’m running them sub 40 psi. I only ask because I burped a tire bad this morning on a rather benign dip. Wasn’t sure if it had something to do with the rims.

Thanks.

No issues.

FWIW, I don’t thing anyone worries about anything over 32c. The issue seems to be a more vertical sidewall

Ran them last year on zipp303s. And never had an issue.

Run them on Hunt Carbon 650b hookless - only a few rides, but no issues so far.

My personal opinion is that burps are more influenced by the tightness of the fit due to the amount of rim tape, rather than some nebulous tire/rim shape interaction.

I’m not a mechanic though…so…hefty grain of salt with that haha.

Still no issues?

I think those lists are just for road tires? Pretty sure anything gravel specific is hookless compatible unless stated otherwise.

I must be on my 6th set of Terra Speeds on 25c internal hookless rims and never had an issue.

There is something weird about the seam where the tire is joined into a circle which means I almost always end up with a pretty pronounced L-R wobble in the inflated tire even on a perfectly true rim. Sometimes it doesn’t really happen on a brand new tire but it’s virtually guaranteed once I remove and re-mount a tire. Has happened to every single one I’ve ever run. Mechanic said it was weird but not faulty or dangerous. I’ve seen other riders talk about this on forums (can’t remember if it was here or elsewhere) and I know some have successfully returned these tires as faulty because of it, but it’s not limited to a specific batch or anything - just something about the way Conti build that particular casing. I’ve never noticed it affecting handling or anything when riding.

Definitely no issues with hookless though!
