I have a set of Forte City ST 26x1.5 tires and would like to put them on to my new wheelset for road use only. Is it ok to use larger sized inner tubes marked as 26x1.95-2.125 I have laying around? By doing a mock up by placing the larger inner tubes around the tire, it seems to fit well. Is there anything wrong with using larger sized tubes such as the 26x1.95-2.125 tubes on smaller sized tires like the 26x1.5?

Sometimes it's hard to get larger-sized tubes to sit right in smaller-sized tires. Sometimes it's easier to pinch the tube between the tire and the bead.

If you've already got 'em, though, give it a shot. Put a little air in the tube before you try to install it - it makes it behave better. If that makes it bigger than the tire, well, there's your answer.

My bikes have bigger sized tubes in the tires, rather than matched sizes. Seems to reduce pinch flats since the tube isn't stretched nearly as much as with the "proper" sized tube. Thorns don't cause a sudden flat either, I usually find a flat tire the next day rather than during the ride.

This has been my experience.

I'd rather have an under-sized tube than an over-sized one.

I ran into this at work yesterday. A larger tube shoved into a smaller tire. I tried for 10 minutes trying to get the customers old tube to fit a new tire. Ended up replacing the tube as well.
