Thankfully getting spare tires isn't really an issue. I live less than a mile away from a bike shop that I also work at every day, hah, so I'm good on tires! I wanted to avoid riding on the new ones as I want to sell them as brand new and it looks like from eBay that the cost of them is more than double what I can get a set of big apples for so I'll probably go that route. I wouldn't mind trying them out but the MU was already a bit above what I wanted to spend even at an employee purchase price so any money I can recoup is going to be helpful.
The only bad part now is having to wait until my new tires come here when I really want to ride my bike that is all tuned up and sitting right next to me!
