I have been commuting on a road bike with 23mm tires (Conti Gator skins after my old tires got several flats).
I am looking at a new bike which will allow a larger size tire as well as fenders, etc. as well as likely Steel for better ride
I am trying to decide WHAT size tire I would like to get.
For reference, I commute just over 16 miles each way, climb about 450 feet each way, and am on roads or bike paths the entire time. The roads/paths can be a bit rough at time and there are unavoidable obstacles in areas.
I could just stick with 23mm, which would be the fastest but also I assume least comfortable and most prone to flats. Alternatively I could go with a larger tire - 25, 28 or maybe even 32mm. Not sure I want to step up all he way to 32, but wonder how different 25 vs 28 would be and how different they would be the just going with 23mm in terms of tradeoff of ride vs speed due to additional rotational weight.
Ideally I would try riding with different size tires to see what I like, but the tires cost enough I am not sure I want to buy two sets to decide
Any input from people who have tried different tire sizes on the same bike is appreciated.
