Ultra heavy duty tube weight and performance

What tubes are you guys putting in all these new tires. I have read that the uhd michelin air stop tubes are 4 lbs. Some say it doesn't handle as well and will give more of a gyro effect. I think I may go with just heavy duty tubes. Just lost in the many choices out there. I know the heavy duty tube i run now loose air fairly quickly (front and rear). Forgot what tubes I have in now, I think irc. Opinions

Unless it's a teeny-tiny hole, puncture any tube and they all lose air REAL quick, regardless of how "heavy duty" they are. Maybe a heavy one lasts an extra micro-second or two, I never could tell.
As to avoiding "pinch flats" ... seems thicker would be better, but I've gotten as many pinch flats with super heavy tubes as with cheapo ones ... proper tire pressure is way more important than tube thickness.
As for the gyro effect ... from a purely physics standpoint - yes, heavier = more gryo effect. Practically speaking, I typically don't run my dual sports faster than 60 - 75mph on paved race courses with rapid turn transitions so the gyro effect isn't a big deal

UHD in the rear and HD in the front.![Smile](https://www.kawasakiforums.com/forum/images/smilies/smile.gif)
It does allow you to run lower tyre pressure without getting a pinch flat.
Never noticed any difference regarding the weight but there must be some.![Roll Eyes (Sarcastic)](https://www.kawasakiforums.com/forum/images/smilies/rolleyes.gif)
Last 2 flats have been torn stems in the front.
(always a risk when running sub 12 PSI)![Mad](https://www.kawasakiforums.com/forum/images/smilies/mad.gif)
I've now put a rim lock on the front as well as on the back.
What's a bit of extra vibration on a DS?![Big Grin](https://www.kawasakiforums.com/forum/images/smilies/biggrin.gif)
Only down side is price.
Oh and they are harder to change on the trail.

Make sure you add rim locks, my old klx did not have any stock. I tore the stem out twice before I was smart enough to do it.
I ran a hd in the rear and a name brand regular in the front. Stay away from the china tubes if you can.

I've been runnin the Kenda Tuff tubes. I dont have rimlocks yet, but haven't had any problems with pinch flats or stems ripping out. I will be getting rim locks so i can run lower tire pressure. Right now w/out the rim locks I keep about 20psi front and rear.

Sounds like you're concerned with weight, durability, and puncture integrity. Why not try Neutech tubeless? I've been running the system for several months now with a little tubeless Slime in them, and it's been bulletproof. Even cactus and mesquite tree thorns haven't caused any air loss. Pointy rocks and hitting rock ledges hasn't caused any problem. In fact, I'm becoming more worried about my rims, whereas I used to worry about my tires.

After I pulled the tube out of my RM125, and saw that it was almost worn through in a few places, I switched over to the heavy duty tubes in all my bikes. The weight difference is insignificant.

I run the bridgestone uhd tubes, FWIW. 15-17 psi.
I think most tubes are made by one manufacturer anyways (at least this is how the mountain bike world works, most tubes have a kenda logo on them regardless of what "brand" box they came in)
