Tubeless Tire Help

I’ve used tubeless on my MTB without issue for years. I ordered a new compressor head and seals last night, but they won’t be here until next week.

One trick you can try is to use a ratchet strap around the tire and rim to press the tire flatter and force the tire beads closer to the hooks on the rim. I’ve used duct tap in a pinch to help seat MTB tires in the past. A compressor certainly helps.

Instead of the inlator (have one) use one of these in the open core:


Get more air into the tire quicker than the inflator

Update! So I think my compressor (old) might have been the issue. With soapy water and an air blaster I was able to seat the bead! 2 oz of Stan’s sealant...might be a year or two old.

BUT....it lost most of its pressure after about an hour. I tightened up valve stem and core, and that seemed to help, but the still felt like it was loosing pressure, albeit less. I decided to go back to riding with a tube for the second straight weekend! Predictably I flatted! Oy this wheel is cursed!

I guess my next step is to try retaping it.

HED Belgium + Wheels--

One of my new schwalbe pro 1's seated perfectly using a standard track pump, the other one required a few drops of chain lube around the bead and a blast with the air compressor with the valve core removed.

Those DT 511's have been great with tubeless. I had to retape the rear because I gooned it up with a tire lever, but the tires seated up and hold pressure very well. I had 85-90# in them before I left for AZ with the gravel bike and when I got back and wanted a road ride, they were still at 75#, ten days later.

Yup, DT511 are great rims..set to build a second pair for a gent this week.

Without the valve, you have to jerry rig a blower. I took a blower attachment with a short section of hose that fits over valve stem.

I had a similar problem. I could not blow enough air past the valve.

Once the tire is seated. Then add sealant. Install valve. And inflate to pressure.

Sorry if you are doing this already.

I have one of these. I use it in the garage and take it with me when I travel. I've seated tires from 25mm to 37mm with no issues.

10 years on MTB.. soapy water. No air compressor, don't even have a pump that has one of those "charge" cylinders. Couldn't even recall all the different tires I've used.

No problems. Soapy water really works.

Never really had an issue where I got a flat bad enough to ever have an special need out on the trail. I think I've put a tube in once. Once you've got a tube in there to get home the tube seats the bead fine.

So I’ve had 2 different Schwalbe tires on this after the initial one that punctured. I got an air blaster - and that with some soapy water did the trick! That’s the good news. The bad news is that it does not hold its air - with or without sealant. I thought it might be a faulty valve, or the valve/core not being tight enough, but it’s a very slow (inaudible) leak that takes a few hours to drain.

Could it be the rim tape or a defect in the rim? I have rim tape, but it’s not quite as wide as the stuff you guys used. I want to go tubeless and forget about it! LOL
