Anyone run tubes?

[Toxic Mark]

I put on a Mitas E07 and it has a slow leak. Can't figure out where it's coming from. Anyone run tubes?

You can, but I'd find the leak. Tubes run very hot at elevated speed and are better left to slow dirt bikes that rarely exceed 45 mph.

Well than I am in trouble!! ???
I now have tubeless on the back but my front 21" is still with a tube on the Tenere..

Really? Half the motorcycles on the road are running tubes with no problems. Very hot, no. Hotter yes, but then again 89* is hotter than 88*. The tire may be a little warmer with a tube in it, but not enough to make a difference. A lot of bikes at Bonneville are running tubes. The big disadvantage to running a tube is that it can't be plugged if you have a flat at 3am. in the middle of nowhere and a lot of tubes are costing in the $20 to $30 range.

If it's designed to run a tube that may be fine but he's talking about running a tube in a tubeless tire and I have read that they run very hot and can fail. And when a tube fails, it goes all at once, not slowly like tubeless usually does.

My dirt bike runs tubes and will do highway speeds but they're in tube designed tires. I'm sure I'm being overly cautious but there are a lot of advantages to tubeless tires and I wouldn't give 'em up unless it's an emergency.

I recently spooned on a TKC 80 up front and for the life of me couldn't get the tire to hold air let alone seat the bead. After several tries by myself and another, I put a tube in and have been running that way for 2k miles. So far so good. My biggest concern is the tire slipping on the rim as there is no rim lock.

 

[OldRider]

Every manufacturer out there puts tubes in tubeless tires There's a million HD's running Dunlop D401's, D402's and Honda, Yamaha, and Suzuki have put more millions of tubes in Dunlop and Bridgestone tires. Very few tires are stamped "tube type" anymore. No doubt about it, tubeless is better, put it's not the only game in town.

I've never thrown a tube in a tubeless wheel. What do I need to do? I guess I don't need rim tape as there are no spokes to deal with. I'm not too worried about slippage because I won't be airing down the Tenere to below 20psi. Do I just pull out the valve?

I have not given up on locating the slow leak. Could it be the valve? I tightened it pretty good? Are there better valves out there?

Take the wheel off of the bike,put 60p.s.i. in offending wheel and put in washtub, i bet you will find leak.Jim

Soap and water in a squirt bottle is a handy tool in this sort of situation. It will even help locate gas leaks around the house.

Change out the valve in the valve stem first. Then go from there.

 

[eemsreno]

You should never run tubes in tubeless tires on tubeless rims. That can create hot spots of trapped air. That is just what tire reps have told us. So we won't do it to a customers wheel.

I'm not saying that I wouldn't do it to my own wheels if I wanted to. The risk is probable pretty low. It's still iffy though.

 

[Ramseybella]

Take the wheel off fill it up.
Dish soap water and spray bottle.
Start at the valve with the cap off.
If nothing happens then around the bead you go. ::008::
If you find no leak in those locations get a deep roasting pan or long plastic storage container that will fit your tire fill with water and start submerging sections your tire and start looking for small bubbles.
When and if you do see one spray that spot down with the soapy water and look for the hole, could have a small pin hole in the tire. ::010::

The leak is about 5 psi/day. I will give these a try, but with such a slow leak it may be futile.

How would I get trapped air? I have a slow leak. Lol.

 

[Don in Lodi]

...trapped air with a tube...
Though most of the trapped air will escape through the stem hole, often for quite some time.
I suspect excess casting extrusion across the bead somewhere. When the tire is off the rim a razor blade can be used to clean up the excess.

I did use soap and water. How fast is fast corrosion. I mounted them on maybe 2 months ago. Also, does this mean the method for finding leaks (i.e., using soapy water) can actually cause leaks?

It takes quite a while to corode.

The first place I would check is the valve stem core, is it tight? Next put some soap all arounf the valve stem. If still no leak it's time to soap the rim and tire all the way around. It's very easy to damage the tire bead putting a tire on. If you still can't find the leak, I would take the tire back off the rim and have a good look see. If after all that and I couldn't find the problem it would be time to stick a tube in it and go ride.

Or take the tire off the rim inspect tire and rim and have it remounted to a different orientation? :
