My back bike wheel has gotten more and more uneven lately, and it sometimes felt like it was moving so much sideways that I was actually moving in small ellipsises rather than a straight line. Yesterday, I finally dropped by the bike shop and to my joy, it was just the tire coming apart rather than the wheel itself being broken. So I bought a new tire. This morning, I replaced the old one, and it was pure joy when I set off for the university, filling up the tire with a bit more air on the way.
Now I just want a new front tire as well..
