Guys,

Seen some posts on here regarding the issue of tubeless tyres falling off the rim and into the rim bed when deflated, and wondered if any tyre combo works better in this regard?

I'm currently using Hutchinson Performance Storm 11 which, when new, inflate like a dream onto the rim but, once they've been on the wheel a while and deflated through a puncture, or to add sealant, they fall into the rim bed and, even with an Airshot canister, can take hours and multiple tries to reinflate.

I emailed Roval several days ago but, thus far, they haven't replied.

Has anyone used a tyre that stays hooked into the rim when deflated?

Thanks for your help.

I think the conclusoin is the lack of safety ridges rather than the tyre itself??

Yes my clx 50 doesn't hold the rim bead of my Rapidair tyres when fully deflated.
However no issues with reinflation with regular pump.
I don't own those boosters and doesn't need it.

Turbo cottons hold the rim better than the Rapidairs Ironically.

There will be stay hooked into the rim most of the times with rims of Reynolds. But all depends on the tyre and rim combinations and also if it is/was the first time mounted or even was mounted multipel times after. Some tyres becomes easier to mount after they where mounted and ridden and will not stay hooked into the rim when they are deflated, so be it.! :wink:

That is a bit concerning, was thinking of getting a set of these for a new sworks tarmac but if tyres fall off the rim when you get a quick puncture or blow out sounds like it could be a bit of a safety issue? Think i'll get something else

If you was riding with inner tubes and get a puncture most of the time the tyre fall off the rims too, so . . . . I think that you must deal with it.

Thanks for the responses guys. By the way, it's been a week now and no reply from Roval. To be expected? I was hoping they might say the Specialized tyre range was designed to mate perfectly with their wheels, but I guess I'll never know......

GP5000's (tubeless) went on/inflated very easily, but would stay seat on my CLX50's. So I gave up and went back to standard clinchers.

However, I then took a gamble and picked up a set of C38's for my gravel bike, with the hopes of running tubless...GravelKing SK's went on perfectly, and do not pull away when deflated. So, I'm not sure if the rim is designed differently than the CLX50's (visually, they appear similar), or if it just comes down to what tire you use?

As far as Roval not responding...I emailed them once about tubeless valves, and got a response fairly quickly.

They are awesome wheels, and clinchers hold the rim perfectly. But, yah, if you are deadset on running tubeless, then I'd probably go with something else.

Personally, I'm just fine with tubes :wink:

I’ve generally found the clx 50 to not hold a deflated tubeless tire well. Beads pop into the center channel. I'm guessing the imminent revamp of the wheel will improve their tubeless performance.

I switched to enve for tubeless setups (they've held all tired when deflated no problem) and only run tubes on the rovals.

Note as someone else said, it's not about the hooks. It's about the bead lock design.

Holding the tyre is part of being tubeless comparible. if the the rim cant hold the tyre use inner tubes.

I was speaking to dr swiss this week and examined this to them and how there rims lack the required feature and there repsosnce, no one has ever complained. If rim manufacturers dont know or care what they are doing then tubeless will never become mainstream. Instead at ertro meetings they are obsessed with the initial fitting. It's an appalling situation

Why would inner tubes be any better?

Because even when the inner tube isn't pressurized, it's resting against the tire's beads and in essence keeping them in place. Remember, we aren't talking huge amounts of force here. When a tubeless tire loses pressure, it usually tries to revert into it's natural shape if there isn't friction or a "bead lock" stopping it.

Today I've learned, that putting sealant in the tire before pumping it up makes life so easy. Before that I was fighting with the new Schwalbe Pro One TLE and my tubeless ready DT Swiss wheels.

I've just started running tubeless as an experiment on my Propel SL0 with disc wheels and Schwalbe Pro One's......had the rear inflated for almost 2 months then had to change the valve core as it was blocked (hard to inflate) ....involving unseating one side of the tire to remove and check the valve for blockages...then soapy water and reflated on a track pump only, just as I initially set it up....too easy!!! Was expecting issues but it didnt happen.

Would recommend Schwalbe Pro Ones all day every day!!

They have truly converted me over to tubeless!!
