Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Basic Tire/Tube question....

Please excuse the ignorance, but my current tire and tube read 700x23. I have anther tube and tire that read 700x25 - both of these will fit on my rim, correct? I tired to put the 700x25 tire on last night but couldn't get it on, but my old tire goes on no problem. I was wondering what the differences are between the two and if maybe the issue is that the tire is just new and needs a little extra forice to be stretched out while being out on, or since the bike came with a 700x23 tire - I shouldn't even try to put a 700x25 on it?? Thanks all!!

Sounds like the tire is just new while your old one has stretched some. I always have a hell of a time getting a brand new tire on.

When you get to the last part of the tire that doesn't want to go on, place the wheel on the ground so the unmounted portion is on the bottom. Then grab the tire on each side of the wheel and push down as hard as you can. This should bring any slack there is to the part you're working on. If you use the tire lever to coax it on after that, make sure not to pinch the tube.

Your bike will take both widths. 700 rims usually accomofdate tire widths from 18 up to 28 and maybe wider but usually fork clearances are the limiting factor.

What you're experiencing is new tires that haven't been stretched. There's a graet deal in variation beween different manufacturers as well. For example some Continentals startech so much with waer, I can mount them on the rims wuth just my finger pressure. Other tires when new are so tough getting on, I cheat and use levers.

Electric blanket trick: place new tire under electric blanket set on high for 10 minutes.

Blow dryer trick: place tire on bath floor and bath towel over it. Carefully blow dry the towel. This will warm up the tire but not too much heat please.

That's not "cheating." It's a practical solution to your problem. I sometimes "cheat" and use a hammer when joining two pieces of wood with a nail
