Again with the tubes!

[Pdrhound]

I just had to cut a trip short due to a nail right the middle of a decent trailmax mission. After doing well on a plug for another 200 miles, it started leaking. 2 more plugs slowed it enough. No tires locally so i just went home. So much for plug and go tubeless. Had to air up twice on the way home. The Sykic tire pressure monitors more than paid for themselves yesterday.

Anyways I was within 300 miles of home so not a huge deal overall to lose 2 days of a 4 day trip.i have had good success with a plug before. This was a straight through hole, on the tread and took almost all of the dynaplug length. If it was at more of an angle that could have been a problem as well.



But on a longer trip where tires are limited, I think I'm going to start bringing a tube. My questions are;

1. Does anyone have experience with running a tube on their S10?
2. Has anyone run a 19 inch tube in the 17in rear?

Here is the long story if you care.

Sangre de San Juans (another horrible RR)

Welcome to another horrible RR. I'm leaving Monday to ride down the Sangre de Christos into New Mexico and come back up the eastern san juans. Rising...

. . . . and took almost all of the dynaplug length. . . .

OPINION: Try the old fashioned "gummy worms" instead. Never had one fail. Especially on a puncture like that.

Your problem was using the Dyna plugs, they, along with Stop ‘n’ Go plugs are complete and utter rubbish. Old school traditional gummy worms for the win.

Dyna plug let me down too. I used them one time. Never again. The shop that does my tire changes said he’s seen several duds. I replaced the dyna plug with a sticky string. The sticky plug has 13k miles on it now

I've never done either, but there's a lot of stuff on the net about the pros and cons of doing it. On Revzilla's website, they say "

"If you insist on running a tube in a tubeless tire, the general rule of thumb is to treat the setup as one load rating and one speed rating less than the tubeless tire says it can handle. That's mainly because your tube and tire combination will be creating extra heat, especially the harder you ride. "

But here's a guy who's done it on a GS and seemed to be fine with it:

As far as running a 19" tube on a 17" rim, I don't think I'd go that route. My experience is with bicycle tubes and not motorcycles, but a larger tube in a smaller tire is liable to create creases in the tube (because of the excess rubber). Creases mean parts of the tube might be rubbing against other parts of the tube; couple that abrasion with the increased heat from running a tube on a tubeless rim inside a tubeless tire, and I think you'd be increasing your chance of a second flat tire. Also, having extra rubber in the way when you're installing a tube is going to increase the chance that you're going to bite the tube with the tire irons when you're trying to spoon the tire back on. I've done that on bicycle tires, and you use a lot less force there than you'll have to use in order to push a bead from a motorcycle tire back onto a rim while avoiding the tube.

If I was already mentally preparing myself to break down a tire while on a trip in order to insert a tube, then I think I would also carry a plug like this:

Since you're patching the tire from the inside, I suspect that this type of patch may have worked on your stubborn puncture, as the repair isn't dependent on a plug (or a tire string) filling a hole. The entire breach in the tire is covered by the patch, and the steel shank is used to pull a section of rubber patch through the hole from the inside to the outside. This keeps water from entering the hole in the tire and corroding the belts. Full disclosure, I've never had to use one of these to patch a tire, since so far the tire strings have worked. I do have a set of them though.

Buy a Nealy tire repair kit and follow the directions. I insert the gummy worm with a little rubber cement, trim it, and set it on fire with a cigarette lighter. Let iI sit for a few minutes after you extinguish the small fire and air up the tire.

The only time I used the wrong size tube in a tire is to cram a 21” tube in either a 17” or 18” rear tire to get me home.

I carry the sticky plugs and also a small tube or can of tube patch glue. I dip the plugs in the glue and push them in the tire. they slide in easier and the glue will set up and help seal the hole. Been doing this for years with very good results. I have even fixed tears in the side wall with 10 or 12 plugs and got home! Of course that tire was trashed. As far as the tube goes lots of manufacturers used to sell brand new motorcycles with tube less tires that had tubes in them. I pulled up one day behind my buddy trying to plug a tire that had a tube in it. He just read the side wall and thought it was a tube less set up. It was a brand new bike. If you are going to buy a tube to carry as a back up why not buy a 17 instead of the 19 or are you just planning on buying one tube and using it on both tires? I have used the wrong size tubes in a pinch and did ok with them short term.

It's very common to just carry one tube, for dirt bikes it's the 21" front tube. I have used it in an 18" and 19" rear....one time for an entire desert weekend.

During my trip up to the Arctic Ocean, my riding buddy got a flat on his Africa Twin front tire. He had converted the tube rims to tubeless by using some 3M tape. It worked great for several thousand miles until it didn't, at one of the worst possible locations on the Dempster Highway....hundred miles from nothing. He failed to bring a tube backup along with him! I had a 19" front tube for the Tenere, have never tried stretching a tube to fit a larger rim but we had no other choice. I got it on there, we had to ride several hundred miles before we were able to get a 21" tube but it was a used one. I suggested we continue on until we get a new tube, I think he rode 500 miles on that 19" tube on a 21" wheel. So yeah, you can do it if the situation calls for it. The biggest issue is going to be how are you going to remove the valve stem?

Also, get rid of the Dyna plugs and just get the cheap sticky worms. I have seen so many failures on those Dyna plugs, no idea how they continue to sell them?

I've had one installed on my front A41. Tire had less than 100 miles on it. Wore the tire out with it still in there. I like them 'cuz it's kinda like belts & suspenders.
