jcarneytx Posted September 5, 2019 Share Posted September 5, 2019 Setup a pair of Hans Dampf for tubeless this spring, been working great so far. However, tore (cut?) a nice hole right between knobs. Even with a plug, it won't hold air. Tore coming down Mulligan drop at BC. Made it down ok, but air was gone by time I hit the sidewalk. Any place in town sell Schwalbe Tires? I can order one, but wanted to see if there was any place local to pick up another Hans Dampf. Pics: sealant drained on ground. Dripping sealant with plug sticking out (still won't seal) Quote Link to comment Share on other sites More sharing options...
cody Posted September 5, 2019 Share Posted September 5, 2019 I've successfully put tube patches on the inside of the tire to seal punctures, so you might try that before throwing it in the bin. Don't see Schwalbe locally much, I used to buy them from starbike.com or bike-discount.de which are much cheaper than buying domestically, but you have to wait a couple weeks for shipping from Germany. Otherwise, I have at least one old Hans Dampf (29x2.35) with some miles left I'll give you if you are near southwest Austin. 2 Quote Link to comment Share on other sites More sharing options...
mack_turtle Posted September 5, 2019 Share Posted September 5, 2019 1+ for gluing a traditional tube patch inside. Even better, get a car tire radial patch. Quote Link to comment Share on other sites More sharing options...

jcarneytx Posted September 5, 2019 Author Share Posted September 5, 2019 Thanks for the tips. For now, I'm cheating with a tube. When time for new tire, I'll set it back up tubeless. I'm a bit impatient and didn't want to wait for it to dry out, then clean, then attempt the patch, then wait to see if patch holds. Quote Link to comment Share on other sites More sharing options...
AustinBike Posted September 5, 2019 Share Posted September 5, 2019 Crazy glue worked for me. Patched 2 tires that way. 3 Quote Link to comment Share on other sites More sharing options...

fontarin Posted September 6, 2019 Share Posted September 6, 2019 I've also got a new HD 2.35. Was going to mount it to a wheel earlier in the week but went with another tire instead. Quote Link to comment Share on other sites More sharing options...

Given the price of Schwalbe tires, I'd fo dang sure give a patch a chance to work. At the least would be to dry the spot from the inside, add another plug and let it sit overnight and then attempt to inflate. Running tubes around here is just roulette, you will eventually be swapping out that tube. Quote Link to comment Share on other sites More sharing options...

When I got my back in April, I caught a rock edge on the creekside climb at the start of Windy Loop, and gashed the rear tire. It was brand new, probably 10 miles on it... However, it was a clean cut, short, and I patched it from the inside after cleaning the sealant out. It worked a charm, and hasn't changed since then. I'm running 30psi.

Didn't hold air. When I got tire off, I did wipe it down, but there was a whole lot of gunk that needed peeling and some further drying out. I just got impatient, so threw a tube in there. I just remembered I have a set of an old set of panaracer rampage I can sub out, so might throw one of those on while I work on the HD. Also, not just Schwalbe tires are expensive. Stopped by Peddlers, looked at a couple Maxxis they had, they were more expensive than what I paid for these Hans Dampfs.

It was originally meant to be a bandaid until I bought a new tire, but then I got curious/lazy and let it ride for months. 1 Quote Link to comment Share on other sites More sharing options...

Rough up the inside of the tire *slightly* because you don't want to scratch deep and start cutting tire cords. And I also learned I had been installing these incorrectly, at least the brand I have. You're only supposed to put cement on the carcass you are patching (the tire in this case). Once dry, then press the patch on. I had been putting cement on both parts.

If you are going to glue a patch on the inside, get some fine sandpaper and lightly sand the inside of the tire around the tear. This gives you better gripping. If you have an old tube you can cut a piece for the inner wall to be a "patch". Superglue the inside, glue some type of patch on top of that, then superglue the outside. Got me through the rest of bike trip as I ripped 2 sidewalls in 2 days. Don't bother to patch the outside, it won't last. And, most importantly, really make sure you have cleaned out the sealant. It might help to let it sit in the sun for a day also. Quote Link to comment Share on other sites More sharing options...

AntonioGG Posted September 6, 2019 Share Posted September 6, 2019 I use a dremel on low speed with a fine sandpaper drum when I patch my tubes. I bet it works for tires too. I'm pretty sure tire shops use a die grinder to get the surface ready for gluing. Is contact cement pretty much the same thing? Could I use an old tube and contact cement? I have a bunch leftover from when I glued laminate for a countertop. Quote Link to comment Share on other sites More sharing options...

If you use part of an old tube for the patch, I think in that case you'd rough up both parts and apply cement to both, let them completely dry (10 mins or so), then stick them together. Where I wrote "rubber cement" above is a mistake. Rubber cement is not a permanent bond. Contact cement is, though. Quote Link to comment Share on other sites More sharing options...

Glue both pieces, let them dry. Stick them together, then *gently* pound them with a rubber mallet. This pounding helps the two sides adhere together. And Antonio, a Dremel is probably good for the inside of the tire, provided the sander does not start chewing up any sidewall threads.

This is first/only set of Schwalbe I've owned. Also the first time I've ever torn a tire. Internet says it's a bit common with Schwalbe. I was using Nevegal/Small Block 8 for several years (26"), but not at Brushy. New bike last year had E13 something or other, but I found those to be slow and squirmy (really large side knobs), so switched to HansDampf. Liked how they worked, but now know they are not as durable as they could be. What would you recommend for rear specific Maxxis? Quote Link to comment Share on other sites More sharing options...
