I know it's probably uncouth and greedy of me, but my first post on these forums shall be in request.
I've been slowly getting into bicycling this past year after bringing up an old bike to college to save on gas. Well, that bike ended up getting stolen this spring, so I wanted a decent cheapo that I could ride for a couple more years before I graduate. I ended up with this Wal-Mart bike, http://www.walmart.com/catalog/produ...uct_id=8399245 I wanted to go with something that I could be ok with leaving outside at all times (not an option to keep a bike indoors where I live), and being partially exposed to Minnesota winter elements. I definitely plan on looking into a more quality bike when I have permanent housing.
Anyway, my tire got slashed this past week, so I ended up going on www.biketiresdirect.com and buying some new tires and tubes (they didn't have big enough tires at department stores, so I choose to order online). Anyway, I got these tires ( Michelin Dynamic Tire Black 700x28) with these tubes (Quality 700c Schrader Valve Tube 700x28/32mm). They are more narrow tires than my old ones, but they seem to fit on the rims fine. The recommended PSI on the tires is 58-87 PSI. However, I was only able to inflate the tires to about 56 PSI with either a pump or an air hose. I assume that something is wrong with the sizing of the stuff I bought, but I'm not really sure because I'm new to this.
Where did I go wrong?
