700 x 23 Latex Tube in 700 x 25 Tire: Possible? Pros? / Cons?
My buddy gave me two Michelin latex tubes that say 700 x 23 on the box.
There is no range given, like on many tubes, that would say 700 x 23-25.
I have used the Michelin latex tubes in 23s a lot and love the ride feel.
These days I roll on GP4000sII 25s and so I am wondering if I can use the Michelin 700 x2 3 tubes with a good result.

Latex tubes are very "stretchy" and should work in your 700-25 tires with no problems. They will, like any latex tube, lose pressure very quickly so expect to reinflate them before every ride.

I have a couple latex tubes that came with a bike I got. I've noticed two things about them: they weigh less on my gram scale, and they lose air rapidly. I have not noticed any difference while riding.
And yeah, they'll be fine in your 25mm tires.

Jeepers, you're talking about 10% or so more stretch on a Latex tube. Did you never play with balloons as a child?

Thank you for your responses. I am reassured that the 23 tubes will fit 25 tires with no problem.
I have ridden latex tubes for thousands of miles on 23s and I don't mind the air loss.
There are rituals I enjoy that are just a part of cycling to me.

My Ritual 12 Step Check List
- Select a kit: Jersey, Shorts, Socks, maybe a base layer.
- Get into the kit.
- Put on the sunscreen.
- Fill the bottles, put them on the bike.
- Put shoe covers, a snack, I.D. & phone in jersey pockets.
- Turn the Garmin on.
- Top off the Tires with a sip of air.
- Put on the Shoes & on the Gloves.
- Put on the Helmet and snap the chin strap.
- Sunglasses go on, with the temple arms over the helmet straps, of course.
- Tell any family members who are home, I love them, my route, and when I expect to be back.
- Start the Garmin and go!

In a pinch, I've used tubes for specced for smaller tires before and they work, but I found them to be more prone to pinch flats. Granted, this was being stuck with a tube like the OP has, and a having a flat w/ 28s. 23 -> 25 should be far less of a problem.

Frankly, if you're getting pinch flats, you're not running enough pressure or more likely you're running a tire that's too narrow for your weight/terrain. A different tube is not the cure. You still have to worry about denting your rim.

I race CX and I really hate the maximum allowed tire size of 33mm. Why not let us run the size that works best? I use tubulars and some of the courses around here are so bumpy I'm forced to choose between constantly bottoming out at 25psi or being beaten to death at a higher pressure. I think a 1.95" MTB tire would work a lot better but cross frames are not designed to fit those tires because professionals aren't allowed to use them in races... (Sorry for the rant)
