However, I strongly recommend that you follow Schwalbe's Pro One 28mm "Maximum Load" recommendation of 75kg per tire. (That's 330lbs for your team, tandem, water bottles, etc.) the 25mm have a 70/kg limit and I am pretty sure the first gen Schwalbe One's 28mm tires have a 70kg/308lb limit. I don't think this older tire is on their website.

I learned about this load limit the hard way.....had a rear tire sidewall failure while decending on my tandem at +45mph. Ugly, ugly wreck....smashed tandem, destroyed wheels, surgery, 10 screws & a long titanium plate plate on my clavicle, stoker had compartment syndrome and more. Post crash I called Schwalbe and learned of their per tire load limit and they said they do NOT reccomend tubeless for tandems regardless of weight. Hard to find it on their website so here's a link: https://www.schwalbe.com/en/road-rea...e-pro-one.html
Be safe and have fun.
I installed a 28mm Schwalbe One tubeless tire on the tandem back in April. After reading this report and others in this thread I took the tire off and installed a tube.

After doing some more reading I called both HED and Schwalbe and then removed the tube and we are back to running tubeless. A couple of issues were pointed out by the reps. 1. excessive pressure can cause a disaster such as you describe. Schwalbe recommended that we not go over 80 psi, especially if we were using rim brakes and doing long descents. 2. aggressive cornering could cause a tire to roll off. The new HED 3 + rims are tubeless compatible.

I discussed the tire load with the Schwalbe rep and he felt that the load was conservative, most manufacturers will normally have at least a 2-1 safety factor built into their recommendations.

We live in the Midwest and do not have long descents. I corner conservatively on the tandem. So we are back to tubeless and stoker says it is more comfortable.

This blog by Jan Heine of Compass Tires is worth a read.

https://janheine.wordpress.com/2017/...road-tubeless/

His recommendation is to keep the pressure below 60psi.

On another note, has anyone flown with tubeless?
Taking a trip at the end the month, I am a little concerned regarding the fluid and pressure in the packed tires?

I've flown with tubeless MTB tires, no issue.

There shouldn't be any for tubeless road.

The maximum possible increase in tire pressure just isn't enough to be an issue.

I run tubeless on our Paketa, but only with UST specified rims and tires (Mavic All-road Disc Pro wheels & Hutchinson Sector 28 tires). The tires are 30mm wide when inflated to 7 bar (~100 psi). I usually run a tad less pressure. 7 bar happens to be the max printed on the sidewall. I would not have even considered any of the do-it-yourself, tape-and-earwax-cobbled solutions one reads about for a road tandem.

I'm only 1,500 miles into my first foray with this setup and I've had one puncture on the rear about 300 miles ago. It was self repaired by sealant. Thank goodness for the sealant doing its job because if I had to use an inner tube to keep riding, I would have been in for a rude surprise: breaking the bead on this tire/rim combination is not for the faint of heart! The puncture was caused by glass or flint which had left a visible cut on the tread. So, I decided I would take the tire off and patch the inside for safety's sake. In the comfort of my own garage, it took nearly an hour of pulling, prying, squeezing, weeping, cursing and gnashing of teeth to get the bead separated from the rim. Once a section pops off, the rest is cake. But getting that first bit started is amazingly difficult. Not something I'd want to have to do on the side of the road. After that ordeal, I immediately ordered a plug kit to replace one of the two inner tubes I carry in my repair kit. The other tube is just filling space as a fool's insurance or maybe for helping another cyclist on the road.

I still have to top off the pressure before every ride, and I've had sealant successfully repair a puncture in a tubed setup, so I'm not 100% sold on the idea. I've had one pinch flat on the rear wheel with 28c tire/tube but it was all new and I was still dialing in the pressure preferences for my stoker. When it comes time to replace the rear tire, I'll probably move my front tubeless back there and transition back to standard tubed tires.

Thanks for the info. That's reassuring.

ENVE SES 5.6 Rims

It's all about if you want to commit to a tubeless set up and just a little bit more of your time and what tubeless brings with it!
We have a set of ENVE SES 5.6 rims, and have had nothing but problems with the tires. We're running Continental Gatorskin Black edition, 32 mm. Tires are blowing out at the rim/tire interface.
Can I ask, what tires do run on your SES 5.6 wheels?

When I figured out that I was patiently reading through a Zombie thread (grrr) I did some checking on your behalf. The poster you hope to get a response from has not been active on this site in exactly three years. The discussion, as you know, transpired six years ago. Six years ago I had hair.

It is a Zombie thread. However, given advancing technology and the more widespread use of road tubeless, it seems worth updating. For us, we’re running 28mm Continental 5000 tubeless on Calfee, hooked rims. ( my understanding is that the rims are made by a Chinese manufacturer to Calfee’s specs).

we run them at 80-85 pounds and have had no issues with blowoffs or tire failure.

Because we run lower pressure than with tubed, the ride is definitely more compliant. And we definitely seem to have fewer flats. In the last stage of the Ride Across Portugal, we got a puncture that sealed itself. We only realized it after the race, when there was sealant on the stoker’s leg.

We finished the stage with the pack. Tubed, we would have been dropped while we fixed the flat.

So I’m pretty much a convert.

Can I ask, what tires do run on your SES 5.6 wheels?

Enve doesn’t spec a particular tire for their hooked rim tubeless wheels, and 32mm is a compatible size, although the widest spec’d.

So a few questions, What is your team weight, what pressure are you running, and why 32mm tires on go fast aero rims?

I’m assuming a light team weight, given that these are 24 spoke rims. At a team weight of 340, we were running 28 spoke ENVE 65. When they needed replaced, and only 24 spoke rims were available from ENVE, both ENVE and Calfee strongly advised us against going with a 24spoke wheel.

So if you are relatively light, then why 32mm tires? Your rims are optimized aerodynamically for 25 mm tires. And given that you’re running Gatorskins, it does not appear that rolling resistance is a high priority.
