I know guys here that run tubliss in knobbies with pretty low psi. 8 in the rear and 6-7 up front. I'm not sold on the tubliss. I run knobbies/HD tubes and depending on terrain run as low as 12 (low speed single track) and as high as 15 (rocks and high speed).


I was on the wall my self. I went back and forth on the the three major tubeless systems: The Bib, The Balls and the Trubliss systems. I chose the Trubliss system for a few reasons


1. Its the only tubeless system that lets you adjust pressures quickly, with both the bib and balls you're stuck with what you get.

2. It locks the tire on to the rim over the entire circumference of the of the wheel

3. Allows for run flats

4. Doesn't lose its effectiveness over time as the Balls and Bib does

5. No Speed limit, The balls and bib heat up over time athigh speed

6. Quick easy flat repair on the trail

7. 100% eliminates pinch flats. The bibs and balls also do this

8. Cheaper then the bib and balls by about 30-40%



It does have two disadvantages; I'm sure there are more but these are the two I can think of.

1. Major learning curve to get on the first time. especially with trials tires. We stalled the tire machine at Discount trying to get the front on. In the end took 2 guys a heat gun and the longest tire bars I could find to get it on.

2. Softer tires are more prone to poking flats.



I also ran HD tubes, they worked well, However at lower pressures they can still be subject to pinch flats are a major pain in the but on the trail if they do pop.


it really depends on what, where and how you ride.

I run a Pirelli mt23 with 8-9 psi on the rear of my WR450 on the rooty/rocky single track around here & love it!

I was just thinking 8 PSI might be a safer pressure to run. A good balance between traction and protection for the rim.


What are you running in the front?

I'm running the original Dunlop trials tires on my Freeride. I've ridden one with knobbies and it doesn't suit me or my riding.


We ride in hot, dry, rocky conditions. I run about 10psi in the back and 13 in the front. On long or faster rides I'll add two-three psi to both.

My suspension has been re-sprung and re-valved for traction, comfort and compliance and I don't have any trouble with flats. i run heaps of baby powered on my tubes/inside tires and find this helps.


A few of my mates have run the "tubliss" set up and have fond they get pinch flats on the bead lock. The advantage is being able to fix the flats in place.


I'm really looking forward to trying the new MAXXIS Trial-Maxx tires when they come available

Currently running Pirelli mt21 9psi. Both tires are DOT as my bike is plated!

I love a trials tire rear but the front is too mushy I find.  I'm running a MT-43 in the back and a Kenda Parker DT up front with 10psi on both on Tubeliss.  Took me a lot of tries to find a front tire I really like.  This is a really good combo for dry terrain and I'd even give it a B+ in sand.


Also in case you haven't done it yet, watch out on steep/loose descents.  The rear trials tires are pretty interesting - you end up sorta racing your ass end down the hill trying to keep it behind you.

In all honesty, I probably won't run them that low normally. I'm just excited about being able to at this point. But in reality I'll probably end up running 10 psi upfront and five to seven psi in the back

I've been using trials tires for 15 years. If there's any rocks run 10 in the back. Also you can pinch the sidewalls at very low pressures which makes the Tubliss system worthless at that point since you're now stranded. I'll trade a bit of traction for less of a chance of failure.


I'm conflicted on front trials tires. Awesome in rocks, like riding on ice if you happen to be on grass. Rear trials is OK in sand, front not nearly so.

I'm sitting here groaning that I read this whole post. Only about a third

of the posts are even on topic.

A little "aside comment" is OK in moderation, but this gets ridiculous,

Agreed, next pass I'll just hand out infractions and call it good. 20 some posts deleted. :banghead:

Cool pictures. I ran an MT43 for a long time on my old DRZ400, but kind of missed the feel of a regular dirt tire after awhile. My new bikes run normal dirt tires. For me the trials tire was a good training thing to help me get up some of the tougher climbs. Maybe I'll try an 803 sometime on a Tubliss. Sounds like it's working for you. That's the main thing.
