One hack I learned for getting the tubs to seat at the valve stems, take 2-4 zip ties, put about 40psi in the tubs, and snug the segment down so that the glue or tape and the tire to lay in properly. Just cut them off after sitting a few hours.

It goes back to the 70’s and my first bike with tubs, hated any bumps from the Clement tires. Worth the time to do this.

Looking forward to the first ride report.👍
