Just wanted to update everyone............

There's nothing wrong with my tube or tire! Remember, don't make fun of me, I'm new! When they LBS put the bike together, the guy left the threaded part of the stem unscrewed and I pumped them up with no problem. When I punctured the old tube and they replaced it, they put a longer stem on it and closed the threaded part........without explaining it to me that you have to unscrew that part to air up the tires!!!!!!!!!!

You learn something new every day, huh?

I felt reeeeeeeeeeeeally stupid!
