Thanks all for the tips, I know I should probably hit up the bike shop unfortunately we only have about 2 of them out here and they are about 20 miles away from my house and with gas the way it is, I wouldn't mind holding off until I can rack up the cash and questions to make the drive worth it.

I guess my basic question is leaning towards the broader aspect of (rim/spoke/hub)'s and tires. If I have a wheel size what is the tire size I need, or in my case specifically if I have a tire in mind what is the listed size of the wheelset I need?

I've read up a lot concerning this and it was helpful on : http://www.sheldonbrown.com/tire-sizing.html

The problem is, is that what is listed is not what is listed on the website's where you can buy wheelsets or tires, for instance i'll put in = wheelset (ISO 559mm) and nothing will come up.

According to the tire-sizing guide an ISO 559 mm wheel would work, I think? I know this might not be what I end up going with but just for clarification in the future so I can start understanding this whole bike thing, it's a lot more complicated than I originally thought it was going to be.

I just want to understand the tire thing a little more so I can help friends out and such if need be. It has been really difficult for me to find retailers that use the tire sizing specifications listed on the above website, are there different sizing measures that retailers use for the wheelsets and tires? Thanks again for all the help I really appreciate it!
