Challenge Chicane Race Tire 700 x 33 TPI 120 Tubeless Folding Black Cyclocross 02074

I've been riding Challenge Chicane TLR tires for a while. I ordered this pair to replace the exact same tires I had just worn down...or at least I thought they were the same. Tread pattern is identical. Label is slightly different. Pressure range on the new tires was listed as 26-35 PSI but on my old tires it was listed as 45-75 PSI. I am a larger heavier rider so I tend to inflate these to the 45-55 PSI range to avoid dented rims from impacts.

I really like the roll resistance and grip of these. I ran them with tubes for a while with a Chicane in the front and a Schwalbe x-one tubeless in the back.

I then tried to set them up tubeless on both the front and back. They went on a tubeless ready wheel a bit easier than other tires have in the past which makes me a little nervous I might burp them once I start running them at lower pressure but we'll see.

My current concern is that they don't seem very air tight to begin with. In one of the tires the sealant is leaking from the sidewalls in a way that seems like a rubber defect; it has a pattern of lines. The leaks should be plenty small enough that the sealant should close them but it doesn't seem like they will last that long. The other tire seems to ok so far.;
