So its been a while since I've ordered tires. I just ordered a Surly Disc Trucker with 700c wheels. I want to get Schwalbe Marathon Plus tires and found a deal here (http://www.biketiresdirect.com/produ...thon-plus-700c) that is way cheaper then on amazon for instance. My question, however, is what size to get?
The Options range from 700c-25 to 700c-38. I assume the second number refers to how wide the contact to the surface is? Either way, I am a little clueless as to which to order.
