What could be the cause of it losing air? The tires are brand new(never used) and brand new Silca valves. I can't hear it hissing air anywhere but its loses air within a couple hours.

Last night I filled it up to 115 PSI and this AM it felt like it was 50% filled. I pumped this AM to 120psi and within a hour it lost some air. I didn't measure it.

If you haven't yet glued it on, I would check and ensure all the extenders are installed properly adn that the valve core is functioning properly. take some soapy water and coat the valve and extenders in it. If you are losing air that fast, it should show signs of it.

My suggestion is to get some orange seal, squirt an ounce or two in the valve, pump it up and spin it. Sounds like you have a very small slow leak. This should/will seal it and you'll be good to go.

Its a new tire and it should work without sealant. I guess I will try to get refund and try a new one.

If you already glued it, then you are pretty much out of luck unless the shop glued it for you and you haven't ridden it. Then you might get a new one. Good luck though.

I have a an older Victoria Corsa CVO CX with latex tube I use for TTs. It loses about 3 PSI per hour.

I think I might have figure it out. The removeable valve core that I attached to the valve extender was leaking air where it threads on. I dipped into water and there was bubbles coming out. I took some plummers tape around the threaded part to seal it better. The bad thing is I took the tire off the wheel and not I have to glue it back on...arggh!
