I am in the research phase of purchasing my first fixed gear although I have been riding the m for a couple of years. I have minimal knowledge as far as specs and parts so I am trying to figure out what would be the differences/benefits for each of having 23c tires compared to just say 32-45c tires? I have broken my list down to 5 bicycles and one out of the four states it has a 1.115 fork which allows up to 45c tires. The other 4 have a 1" fork and all come with a 23c tire. I understand this is just a difference in the width of the tire but I would like to know the benefits of having a thinner or thicker tire, as well as disadvantages between the two. I also understand that the fork can be switched out and upgraded in the future. I am not planning on using the bike on dirt paths or "offroad" as i do not want to put the stress on the frame.

Lots of info here Bicycle Tires and Tubes scroll down to width and pressure.

Do you ride rough roads? If so, wider tires will add comfort by smoothing out some of the road shock.

Click Advanced Search in the top right corner, then type Tire Sizing and do a search in "titles only."

There is 3 pages of topics.

thanks

no i ride in florida and the roads are very smooth, and i generally don't ride in the rain as i dont think its good for the bike
