Tubliss with trials tire

[roostafish]

I have been running the Tubliss system for nearly a year now. I have said it before, and I'll say it again here. Tubliss is the most cost effective, best modification I've ever done on an off road motorcycle.
Many of us know a trials tyre is a good, long lasting tire with great traction in most places. I have found with the Tubliss that any knobby is fantastic because you can run such low tire pressures. In my experience, the Dunlop MX 31 is thet best tire for my conditions, and frankly makes the trials tire unnecessary. However, I am curious and there is a local riding spot that as much as requires a trials tire. So, I bought one and mounted it up on my Tubliss equipped wheel. So, to the point.

The trials tire with 6psi worked very very very well for me this week. I took it out Wednesday in a downpour, and showed that it still doesn't work in gooey conditions, and has absolutely no braking traction in the same . However, today I went to another local riding spot, and found that it worked very well. While the braking traction is nearly nonexistent, it can be overcome with a modification of riding technique, mostly just waiting for something the tire can grab onto. The beauty of the trials tire with the Tubliss is that it works exactly the same as on a real trials bike. Trials riders often ride with as little as 2psi in their rear tire, and they can do unreal things. I was able to do crazy stuff with this tire today. Mostly over some rocks and logs, but suffice it to say that it works far better without a tube. One can actually run a low enough pressure in the trials tire without fear of pinch flat to make it work like it was designed to work.

What trials tire did you run?

I modified a trials tire by cutting out every third row of knobs. My intent was to improve snow traction. I have yet to test it in the snow. With 1 short ride on it I found it provides much better traction in the loose rocks/soil. Otherwise, it functions about the same.

I am running the Dunlop D803.

We ran into some snow yesterday, and the snow is not where that tire shines, for sure. Though I didn't suffer any more than the other blokes in our crowd.

i ran mx31 rear, tubliss, 6lbs today and it was amazing. no traction issues anywhere. grippy as a trials tire.

[roostafish]

Agreed. The trials tire with no tube lets you play on rocks and logs like a trials rider would, but for trail riding, the MX 31 with 6 psi is truly better, mostly because it works EVERYWHERE.
I'll continue to run the trials tire because the private riding area I get to practice at nearby is a stickler for riders having them.

How technical a trail have you succesfully ran the knobby/Tubliss? How about wet uphill rock faces, off camber slabs, skinned logs, etc. The rains hear have put a hurtin on the trails and upped the level of difficulty on some hills. The trials tire still works great, I'll consider the Tubliss/knobby but do not want to give anything up.

Today my family was all out celebrating earth day. With our throttle! My wife's idea. Gotta love it.
Anyway, more confirmation on the trials tire. There's one creek crossing with a particularly steep hill right out of it that climbs for quite a ways. Near the creek there are lots of rocks and tree roots, which the wet trials tire just grips and grabs. After grinding through that though, the hill is just perfect garden loam with seemingly no bottom. When the mud is soft, and there's no bottom, or anything substantial to grab on to. The trials tire, even with 6psi just isn't the ticket when compared to an MX 31. It's great in it's element, but I think the Tubliss system has pretty much rendered the trials tyre a thing of the past for me.

Ok, you guys have really perked my interest for an MX31. My usual rear is a trusty Pirelli MT16 (with TuBliss currently) but the door is always open to try something else.

So how do you think it would work in New England? Rocks, rocks, and more rocks, plenty of roots and mud, plenty of scetchy technical stuff, fast rocky old washed out dirt roads and rocky power lines. Not much sand really.

So what do you think and what is the longevity of this beast?

i've got 12 hours on mine (race/flip/race/practice.) so 4.5 hours race time, 8 hours practice. i'm probably gonna replace it for next weeks race... but it still looks good..

Iv ordered a MX31 for what could be considered my home enduro.
Its a mostly clay, and im hoping it rains.
Im just slightly worried that the MX31 will chew out on the clay? Although from reading this it seems that it will be fine.
I wont be running it at 6psi with the tubliss because I havent got one yet
