Wiz,
The reason is they are easy to replace, and do not require a sense of touch to adjust. Put a new one in and it should be fine. Another thing about being a milenial; do the easy thing! I just finished the front wheel for my Ochsner and it is waiting for a new Vitoria kevlar tyre installed to match the rear. I am finding some interesting things about the 59 cm frame I have that I bought to match the decal placement on my 57 cm. The rear triangle has been stretched to fit a seven speed hub. Argh! but the wheel build was a success. Smiles, MH
