tires

People are telling me that i will be slower on 25cm tires than 23cm tires.
I don't see that it's going to make THAT much difference, I'm not a racer.
Thanks for the Sheldon Brown article.
He seems to agree with the Cascade bike club guy who came to my company to talk about urban biking. He said that most people have too much air in their tires. If a 250 lb man has his tubes at the max inflation of 90, someone like me (125lbs) can do just as well with less air in my tires, and so doing have a more comfortable ride..

Sticking my nose in here with a question. Dh has 23cm and I have 25cm tires. I have trouble keeping up with him at the best of times. Do you think a tire change might help even a bit? I'm looking for any advantage I can get...

Interesting about the inflation. We don't have a guage so we have to guess how much air we have. Guess it's time to buy one.

35 to 28... now *that* makes a huge difference.

25 to 23 - at that point, the other differences in the tread might make more difference. First off, some tires with the same size number just aren't the same size, I don't care what they say (like dress sizes). Other tread differences and how much pressure is in 'em will also make a difference. Chain "stretch" will make a difference - how many miles on the chain? Seat adjustment? Foot position? Stroke technique ("round and round, not up and down)?
Lots of things to think about for getting that edge... more chocolate or other caffeine source (or slip him decaf) would prob'ly do it :-)

Hee Hee! Kelowna -- this is just like me! I have trouble keeping up with DH too, and keep looking for little things (like here, honey, have a trailer and drag dear grandson along!)

Yup, get a tire gauge -- if my tires are below some number, it's like slogging through mud compared to having plenty of air! (DHisn't as picky about his tire pressure, he teases me -- says I would go nuts with those road bike tires, cuz they need "such high pressure")
