23c or 25c tires
I'm looking for some help with tire choice. I ride about 3000 miles per
year and participate in an annual 8 day charity ride for the Arthritis Foundation. My road bike came with 700x23 tires. Since I weight in at about 195lbs, I was wondering if going to 700x25 tires would be a good choice. I don't do any racing, just training rides for the annual charity ride. Any advice about tire width is appreciated. |

I like my 25 mm Michelin Pro race tyres very much. Lou |

There's a chart online in this regard somewhere, but the reduction in rolling resistance by going from a 25 to a 23 is negligible. For your riding, the bit of extra comfort you'll be getting with the slightly wider tires is well worth it. Go with the 25s. Jim |

When I say "a little" I am talkin in the range of 10%. Make sure they will clear your fork, brakes, etc While you are at it, consider Avocet FasGrip Carbon 12 Duro 28s. The cost the same; the "little" becomes more significant. They clearanc issues are also more significant. Specifications http://www.avocet.com/tirepages/carbon12_specs.htm - |

Given identical construction and pressure, that should be an INCREASE in rolling resistance. See http://www.schwalbe.com/index.pl?punkt=265 under "Why do wide tires roll better than narrow ones?". For your riding, the bit of extra comfort you'll be getting with the slightly wider tires is well worth it. Go with the 25s. Especially if they roll better. John |

That would certainly be an improvement. If your bike has reasonable tire clearance, I'd suggest going wider, say 28 mm for spending that much time in the saddle. I'd particularly recommend the Panaracer Rolly Poly or Avocet FasGrip Duro, see: http://sheldonbrown.com/harris/tires/622.html Sheldon "Comfort And Durability" Brown +--------------------------------------------------------------+ | Pentagon officials believe they have been unable to locate | | Bin Laden because he has found an ideal place to hide out. | | 1 It is easy to get in if you have the money. | | 2 No one will recognize or remember you. | | 3 No one will realize that you have disappeared. | | 4 No one keeps any records of your comings and goings. | | 5 You have no obligations or responsibilities. | | Pentagon analysts are still puzzled, as to how Bin Laden | | found out about the Texas Air National Guard. | +--------------------------------------------------------------+ Harris Cyclery, West Newton, Massachusetts Phone 617-244-9772 FAX 617-244-1041 http://harriscyclery.com Hard-to-find parts shipped Worldwide http://captainbike.com http://sheldonbrown.com |

I doubt this has anything to do with the type of tires, but I would expect that for punctures by sharp objects, wider tires would be at slightly greater risk due to the larger swept area. Generally, the reduced risk of "snake bite" pinch flats with wider tires more than compensates for this. Goat heads are not something we have in New England, and I'm not familiar with their life cycle, but if they're like other plant seeds, their distribution will vary according to the time of year.
