My back trial tire leaks air 

What can it be? 

Could be a lot of things... a lot of older bikes have a rim strip that might need cleaning or replacing and if so I would suggest considering a smear of RVT sealant around the edges to help.

could be the valve stem has a leak in the valve core or crack if the valve core replacement should fix it, of stem is cracked it’s a pull the tire job to replace or find one of those quickStem replacements. 

You could have a torn bead on the tire, or a poorly fitting tire as there has been a few reports of some tires not working with some wheels.

theres a few possible things.

good luck

bath of water should show where its leaking



wack the pressure uo to like 40 psi plus put it in clean (ish) soapy water and rotate - you should then see a stream of bubbles from the point of failure. the answer to this will guide you on how to fix it - could be cracked rim, leaking spoke/rim tape, the valve, the seat of the tubeless tyre on the rim or even just a puncture
