ditto on the 25/64 bit.

I got to ride them today a couple of times around my favorite 28 mile single track and sand wash loop - and wasn't expecting to actually feel much, if any, difference.    I was shocked - and the guys I ride with were shocked at how much faster I was.   In dry hardpack I felt as if I was riding on moist dirt - where my tires usually give up when pressed on the side knobs they just kept sticking, in rock gardens the ride was much more controlled, and steering was more precise everywhere.   (For reference I'm an old intermediate (at best) rider on a YZ250 2 stroke with "magic" suspension running IRC VE 33&35 tires.)

I hope the guys I race against don't find out about these things.

If you like your rims you'll still have too!!!

I did the Big Bear dual sport ride last year, can you say rocky? It was tough and traction was limited, i ran 16psi so i wouldn't have to deal with pinch flats. Needless to say i was deflecting off rocks like crazy, towards the end on the second to last climb i couldn't believe how much traction i had, turns out i had a nail stuck in my tire and was down to about 5psi. That sold me on the idea of low pressure, Bib Mouses were proven but pricey and didn't last long enough, not to mention the decline in permormance as they break down. The tubliss system seemed to fit the nich between HD Tube over kill and spendy Bib Mouses. I ordered up a 21 front and 18 rear last thursday, Friday they arrived! I used Armorall as the sealing aid, took a little bit of time getting the rim inside the rear tire Dunlop 739 Desert made of concrete. But both the front and rear seated first try, and three days later both are spot on at 10psi right where i had filled them too. The only thing i would worry about would be puncturing the inner liner but that would take a long nail with and to fix that all you would have to do is pull out the Tubliss and slap a tube in to make it home.

Instead of putting in a tube try "plugging" them like a radial car tire.

One rubber plug, a little glue, a co2 cartridge and I was on my way.

Just like any tubeless tire.

there in stock ***!!!!! im being told mid April!!!!!!!!!!

YUP!!  ... and, make sure to get the right plugs for your tire... there are two types;  Brown plugs and black plugs (or "strings" as they are called).  Brown are self-vulcanizing and require no rubber-cement - Black are non-vulcanizing and require rubber cement.   ... I carry both, and a small tube of rubber-cement to help the plug into the tire (if needed).

Ok where did you get them from im having no luck all sold out?

Just a follow-up now that the snow's starting to thin out.  

Finally got to ride on mine and am quite happy.  It's holding air with zero issues and I just need to bring myself to keep lowering the pressures to get the traction benefit.  Very, very happy with both the product and the service.

JAT--you mentioned in passing using old tires; have you had any troubles with leaks on used rubber?  I've got the tire that I pulled off to mount the tubliss that has some life left in it that I'd like to finish off--I guess I just oughta suck it up and give it a try, eh?

Waiting for a few free moments to install the front that showed up the other day--can't wait!

KS-are you SURE you actually had a leak around the spokes?  The volume in the red liner is small but significant and the air between the liner and the tube has to go somewhere when you put that 110 psi into the tube--and the only real outlet is the spokes.  I followed the advice I found somewhere during my research before I ordered and gave it a couple of hours before I got worried about the air that I found escaping around a few spokes and sure enough, it quit and the tube has held pressure just fine.  The small volume of the liner tube makes it really sensitive to air loss during pressure checks and temperature-related pressure changes, but I've always checked my pressures before riding with or without tubes and I see less variation with the Tubliss than I ever did with tubes.

No issues whatsoever.  Just clean out the old tire with soap and water... and make sure to get any tube-lits out of the carcass... and any rocks, sand or what have ya.  Mine has lasted, and lasted.   I've even mounted them up to old tires, and near square rims (testing and trying to get them to fail)... so far, so good.

Thanks JAT.  Always helpful, I appreciate that!

Turns out I got a bad out of spec one.  That's why it leaked I'm told.

I just got back from 3 full days of riding in Moab Utah including going up pritchett canyon http://www.4x4now.com/33jspc.htm  I have only been riding a few years.  I installed the tubliss system both front and rear the week before the trip.  I was worried to try a new setup when I could be many miles from the truck and SOL if it did not work well.  My buddies were a bit intrigued and skeptical.  I don't usully ride such difficult trails and was worried I would need to have my friends help me up some sections.  I aired down the tubliss tires to 7 rear and 9.5 front.  I rode up every obstacle without any assistance far surpassing my usually skill level.  The tires hooked up unlike anything I have ever ridden.  I felt like my dunlop 756's were trials tires.  They also were awesome in the deep sandy washes.  The suspension and tires were better everywhere.  The tubliss system made me a better rider everywhere.  All my buddy's (these are the same guys who sold me my first bike in 05 and showed my how to ride in grad school) kept commenting on how well and improved I was riding.   I really felt like the tubliss system made a significant difference in how well the tires gripped and tracked in every condition.  I am a believer.  I gave away all my spare new tubes and will not be going back.

... if you are truly trying to order off the website, and they tell you some later date they'll be available....  CALL JEFF at Nuetech.  He'll let you know the scoop and you might just be able to get your order filled.

Understand this isn't some gigantic company pumping out a product. If you call, you'll get the warm and fuzzy from one guy... not the entire lame customer service department of a major corp. who know nothing but dates and quantity.

WHEN IN DOUBT.... CALL!!!!

Here is my First Ride Impression: Take it with a grain a salt, for being a competitive shooter more than anything its probly like asking a golfer to rate a race car.



Couple of caveats to proceed my first impression review.

1. I switched to new Different tires.  Previously I had Dunlop 756 Rear, and a 742 Front. New tires were Dunlop 952 front, and Maxxis IT desert Rear.  The maxxis by itself weighs 2 pounds more than the D756 Rear.  

2. I switched gearing from a 50 tooth rear to a 46 tooth rear.
3. I'm the type who really tunes into to the way something feels. It usually stays with me long than most. Sometimes this is a plus, sometimes a minus. I usually have to put in a succession of laps to reprogram to a new feeling and get back up to speed, unless I reject it outright and return to previous baseline.


All that being said, I started with 18lbs front and rear. Most of what I noticed was the bike didn't jump out and go like when it had the 50-T rear gear. Felt like a wide ratio Tranny. Rear end of bike on acceration was heavier. Turn in for that front tire was not as positive as the turn in on the 742. I figure because the knob spacing is wider and less dense on this 952.


After a couple of laps around this course, not an MX track more of a tt track. I remember thinking what Jeff @ Nuetech said Kiedrowski said. Really didn't care for the feeling necessarily.


So then I dropped the pressure to 12lbs front and back. This felt about normal, except bike no longer wheelies anywhere, it just goes. Initial turn in with the 952 not as sharp, stable predictable as the 742. Enter turn in was slower. The rear hooked up better than I thought for a desert tire. Probably a combination of less gearing etc, as to any particular thing. Did several laps. Noticed however than I could definitely depending on the attitude, (lay of the bike, either upright or cranked over) feel the tire sidewall playing a more active roll in the feel and feeback. Once cranked over in loose sand. (Once they were set in the corner) the tires felt pretty good and did hold lines probably better. Again I could feel the added benefit of the sidewall searching for traction as opposed to just spinning up and off line. Again probly a combo of gearing and tire set up. Had to do several more laps to get a better feel for the turn in of the new front.

Next dropped the pressure to about 8-1/2lbs front and rear. The image that most prevailently came to mind at this setting was that of a 60s-70s era drag car jumping off the line, and flexing the sidewalls as it launched down the track. It was just like running low pressure in a car.

Now, and this is a personal thing. The low pressure had some good points. namely Straight ahead traction, the tire is now working as a distinct and tuneable aspect of the suspension-drive package. This was a plus. Intital turn in was slower, and at times a bit washy, because it turned like a tire with very low pressure. I myself prefer a crisper more positive turn in, and so my reaction was to want to put the pressure back to about 12lbs. But again, once cranked over the thing really allowed the tire to wriggle for every bit of traction it could find. In Slippery woods with wet rocks and wet tree trunks this would probly be the way to go. You can make the thing like a trials bike.

I myself prefer the feeling of 12lbs, as less pressure takes away from the positive turn in. Sidewall traction is definitely up over a tube set up. Tire feedback, (tire flex and cushion) is distinct from suspension. Its like listening to a tune where you have the choice of hearing it as a whole, and or hearing the individual instruments doing their part as well.

I didn't get to ride enough to really get over my dislike for the turn in of the 952 tire. (some shooting buddies came by and had to stop and work with them on marksmanship) It probly holds a little better in loose stuff that the 742, maybe, but to me it was not as clean turning into certain corners and made me a little less confident going in hot. Could change over time.

I think if a person like the feel of low pressure tires Tubliss is definitely the way to go.

The ability to tune the tires as a integral part of the suspension package is a big plus in my estimation. The tubliss system allows for this.

I'm going to try and get a couple of the real motorcycle racers that I know to try this package.

Anyone else confirm these descriptions of the perfromance of this system?

One last thing.  Jeff is one cool cat.  Definitely, definitely give the guy a call if you have some concern.  You don't find many companies run like this in America anymore.  His concern for the customer and passion for his product are to be comended.

I never liked the 952 on front. I run em on the rear, but usually go with a 956 or 942 up front.

I'd try experimenting with different tire pressures front and rear too (not keeping both equal).

Great writeup on your experiences with new tires and the tubliss. No offense but it sounds like you might not notice the full effect since you are running different tread altogether. I am anxious to hear your experiences if you went back to a tire you were familiar with. I really like your description of running the lower tire pressure in the front.

Overall the tubliss did allow you to play with pressure more than usual and keep your bead locked and make tire changing easier right? If so it sounds like it's worth the investment.

I guess whether it makes tires changes easier is relative.  To me changing tires sucks nine ways to Sunday anyways, especially rear desert tires.

and yes I'm going back to a 742 front.

I would list the Pros as:

1.  Gives a livelier feel from the tires, (tire feel is disticnt but in unison with suspension)

2.  Allows the Tire to be tuned as a seperate part of the Suspension.

Can't Say is its better for flats cause I haven't had any.

I doubt I'll go really low on the pressure, because I prefer a crisper turn in.  That's just me.  The ability to keep riding on a flat tire without it coming off the rim, (as long as the inner tire doesn't pop) could be huge in a desert race.   I'll find out next year.  Definitely using Tubliss over a Mousse flat.

KS - your write-up mirrors a lot of my recent experience with the different "feel".   (I didn't go into as much detail in my own review.)  I like low tire pressures and like the TUbliss "feel".  I like being able to run low pressures for traction and yet have some sidewall stiffness for steering response.  (I'll give up a little steering response for being able to hit rocks the size of my feet without feeling them.)

I have noticed that my tires have to "warm up" now - like a road race tire - before they perform their best.   As time goes by I'll figure out if it's just these IRC's, or the pressures I'm running, or if it's the TUbliss.   (Without the added friction of an inner tube it's possible it takes longer to build a little heat in the tires.)

Bottom line is I'm sold on the TUbliss.  But - using them changes the way tires work so - I expect a whole discussion to develop around which tires respond best to the TUbliss.

That's very interesting.  I didn't ride long enough to warm the tires.  I think my issues was probly with the 952 dunlop front.  I might start digging on the lower pressure with the same known good front tire.

I wonder, (not that it makes a Sh*%t, cause these tires aren't that expensive to replace in the grand scheme, but) how these tire sidewalls will wear on tires which maybe weren't intended to use them as much as they now will.  Will it effect tire life in a different way after a while. I wonder.

On a side note for the Arizonans, what's the round about elevation of Parker Az?  Bitd has the parker 250 and I'll probably be ther next year.  probly have to rejet....
