Quick question. I just replaced both tires on my bike and it's been like a month since i put the tires on. i go down to take my bike to work and what do you know a flat. I know they say its not a good idea to fix flats and you really should replace the tire, but what do you guys think. My main question was also should a brand new tire get a flat so fast.. there is no nails or anything in it. Do you think the shop will fix it or replace for free?
