250-500cc Tubliss system

I have been using tubliss for over a year and really like the system, I use bridgestone 403 and 404 intermediate tires at 10 psi. I ride eastern conditions with lots of roots and rocks in KY. Some are saying with tubliss use dunlop mx71 front and d739AT rear, harder ties lower pressure. I am thinking of trying it out and they recommend 4 psi. Im thinking at such low pressure will the red tubliss liner wear out because of touching the tire much more with this lower pressure.

The red liner already touches the bead of the tire that's how it works. The bead of the red liner squeezes the bead of the tire and locks it against the rim. You should have no problems people are running the d739at with 0 psi in that set up. I run 7 psi with an MT43.

I know how the system works. Im talking about the outer diameter of the liner rubing the tire.

i run really low pressure like 5ish no problem and i got as many rocks n roots as anybody

The liner rides in the drop center of the rim so I could see the hard terrain tire flexing to the pointof touching the red liner. You should be fine. Give us a ride report whe you can.

do you guys have issues with air leaking out if the bike sits a week or two? I got them when they first came out but I had them both almost go flat if they would sit over a week. Filling them up before a ride they would be totally fine during the ride, but it was so diconcerting I switchwd back to regular tubes.

Mine lose a little air but dont go flat. With standard tubes I would take for granted checking the air, now i check air religiously.

The instructions state clearly that the bladder loses air over time. If thats an issue, fill the bladder with nitrogen.

I've been using Tubliss since they came out with an 18" rear system.... That's been a while & I have had ZERO problems. I've used many different tires & the best has been the desert tire on the front & rear. The MX-71 front & 739 rear was golden, but the new AT-81 front & rear are the best combo with the Tubliss system I've ever used when racing. And of course I have a trials tire (MT-43) mounted on another rear wheel just because I love a trials tire in the rocks & roots from time to time when trail riding. 6-7 psi in the front & 3-5 psi in the rear.

huh i missed that. if thats the case i may have to switch back then

Im going to try the mx71 and d739at the next I change tires out in the spring time and run about 4 psi.

Go ahead & get the AT 81's front & rear.... You won't be sorry.

Not my store, but it was the first to pop up on the old Googler

I check the pressure before every ride.... But I did that with the tubes too.
