I started commuting a couple weeks ago and love it. It's only seven miles, so I'm not concerned about speed, but I really don't want to bother changing a flat, so...
What setup do you use to reduce the risk of flats?
The road on my route is pretty beat up and I'm on an old roadbike. I'm thinking I should get a tire liner, a thorn proof tube and some heavy duty tire. While speed isn't a concern, would this be like riding a solid rubber tire and give no cushion at all?
