I was getting ready to take my weekly stroll last saturday when I notice my rear rear rubber was a little low on air. 
Shrugging my shoulders, I thought what the hell and took it out for a nice drive. 
Needless to say, one hour later, my rim was riding on my tire and I permanently damaged my newly purchased toyos. 
There I was sitting on the side of I-5 waiting for my wife (90 minute wait). Thank god, I am blessed with this beautiful woman.
It started to rain, I left my top at home, and no spare in the car; fortunately I was able to pull over under Convention Center overpass and was able to stay dry. :redface:
A state troopers pulls behind me and kept me company by talking about my car. He was interested in the performance.
I am posting this to help others by not making the same mistake I made. Our tires do no hold much air at all and if it is low, take care of it right away. Come to find out, my stem was leaking.
