Problems with sealent/NBX lite

I have problems with mounting my Nokian NBX lite tyres with sealent from Stan's. I tried these tyres on my Mavic Crossmax rims, and they loose air within a day. Looks like the air escape at the tyrebeds. Somebody got a solution?

Check the bead. I ran a one as a rear with sealant last year and for whatever reason after about 250 miles the tire had been worn through to the cord just above the bead, all the way around on both sides. Tire was done. I'm not relying on the nokians this season, great tire and fast to boot, but durability leaves a lot to be desired.

not Stan's recomended.

Stan thinks these have a weak bead. Are people having trouble with the bead blowing off? What setup and what pressure?

Tried it, wasn't reliable, went back to tubes.

I got them aired up on Mavic UST rims no problem, they held air very well. I only had to add a couple psi every week. The problem I had were punctures, after blowing out the rear tire hitting a very small downed tree (the size of a root), I said I'm done with this! Went with tubes in my "Stans'ed" NBX's got 3!!! flats in one race, one on a crash that ripped the bead out of the front tire. Ordered a new pair of NBX Lites, mounted them with Maxxis Ultralite tubes and have had 0 flats for several months of riding after that.

Summary, love them with tubes, hated them with Stans.

Run OK for me

I run them at 35-38 psi on Bontrager Race Lites w/ Stans strip & sealant. They do lose air after a virgin set up but it seems normal in my experiance w/ Panaracer & Specialized.

I think the bead does separate from the rim some during riding cuz I see markings emanating from the bead/rim interface in a dark, outward pattern looking like it is due to centrifugal force. I've felt like there are cases where a turn or good bang pops the bead & a bit of sealant is released. The pressure has never dropped to where its noticeable during the ride.

My problem is the the NBX Lites don't hold up well. Worst tire I have ever used in that respect but I do love them dearly for racing in the rock free, fairly tame midwest trails.

Thanks for all the tips, you all. I have give up with this tyres. They just don't hold air. tried about everything. I bought a Schwalbe Racing Ralph and a Nobby Nic and mounted them with no problems.

You made the right choice to go with the Racing Ralph. The NBX Lite is contraindicated on any terrain that has rocks or sharp objects. Nino seems to feel that it's a good pick for the loamy trails where he rides, though. One trick for sealing beads is to lay the wheel sideways for a couple hours on each side.

Stans does not recommend Nokian tires. http://www.notubes.com/support_tire.php
