I just went through this with my Ksyrium Pro Carbon UST rear wheel. I thought the Yksion Pro UST tire was OK but it seemed to have multiple flats. It would not seal well leaving goo along the frame seat tube. Fortunately, I was never stranded.
I contacted Continental because I wanted to use the GP5000 TL.. Their customer support was great. Responded quickly but suggested I try other tires. They did not think the tire would be able to be mounted on the rim.
I ended up ordering Schwalbe Pro One TLE. Their customer support replied to my inquiry stating that the tires were fabricated to UST specs. I had my LBS replace the tire. Rim tape was fine. I could not mount the new tire. LBS did it in about 30 seconds. With all the Covid precautions, I could not watch to see how they did it,
The Schwalbe is working well and quite a comfortable ride.
