So the bike I am picking up Friday comes with the Kenda Happy Medium tires. I plan on riding 90% on road, and maybe packed dirt paths now and then. I am assuming these tires would be fine for the little time I spend off pavement, but I'm thinking they could be a little better for pavement. The LBS said they would switch them out for me with something else. I found these Maxxis Overdrives. They seem like a really good street tire, and would be able to handle a little dirt. I am thinking I would like these better. Anyone have opinions on either of these? Anyone use either of them? Thanks for any input.
