I noticed it first on my bike tires when I increased the air pressure to almost the maximum and used it on my roller (a treadmill-like device that lets you ride your bike indoors --> http://www.bikesomewhere.com/images/big/elite_parabolic.jpg )
I also noticed it on my car tires after I increased the tire pressure (recommended in hybrid groups to maximize mpg). But I didn't notice it until I drove the car on the freeway. Most of my daily commute is on surface street.
Based on the above, my theory is it happens when the the tire heats up. Does the spike grow until it falls off or does it recede back to the tire? Does it have any effect on the tire?
Here's a picture of how it looks like --> http://farm2.static.flickr.com/1169/1107702767_e08404d9c8.jpg?v=0
I want to know the science behind it hence the category.
Thanks!

Although I'm not satisfied with the answers since the car was bought brand new in March and I only noticed the "spikes" this month, I'll give cdf-rom the 10 pts. Also a TU for all the answers. Thanks!
