Bumpy Ride

While cycling to school today, my handlebar felt like it was pulsating. At first, I thought it was due to the stones on the road due to the road widening effort. However, I soon realised that there was a rhythm to it.
Couldnt figure out what was wrong so I just pedalled all the way home. It was one heck of a bumpy ride!
Turns out the tublar tire was misaligned. A poriton of my tire was no longer sitting in the groove of my rims!
Check out the pics.
