Just bought a 7100 and I live in south Florida. I do mostly flat street riding.

The first thing I want to change are the tires from the stock 700x35 to a 700x28 high pressure or maybe even a 700x25 to gain more speed.

Which tire size would you select and which tire would you buy? I want to avoid tire problems.
