I use silicone spray on the bladder & liner , slime in the tyre & around the beads . I have 3 sets of tubliss all hold air in the tyres but the bladders do loose air about 10 -20 psi per month. I have read that putting slime in the bladder stops them losing air but haven't tried it

 

With Tubliss the seal isn't between the tyre and the rim, it's between the red liner and the inner side of the tyre. Leaks are usually either damage on the lip of the red liner, damage on the inside of the tyre, or one I've had a few times, weapy valves. I ended up buying a bag of 20 or so valve inserts and changing them everytime I changed tyres.

Back to the other part of the question though, I'd say a tyre soap would help it seal, and I know a few guys on here have been using it. I just use slightly watered down silicone spray and it's always worked. One thing you could try, is to only pump the inner liner up to about 40-50 psi and then try pumping the outer chamber up to the same and it should start farting a bit of air out, it may help seat it all a bit better and squirt any lube in to any gaps.

If it turns out I'm speaky bollacks, I'm sure Pindie will be along soon to put us all right!

 

Is the rim damaged? I've never had an issue, but I do put slime in too (belt and braces).

 

How is what you wear relevant?
