I believe the tubes in my Trek DS are for 700c 35-42mm

Most of the tubes I've bought lately have a range of sizes they can be used for just as they do on jbooker82's DS. So I would think you would be able to use your wife's tubes.

Yes you can.

Your 26" tubes aren't going to fit without severe stretch, assuming they are MB size.
There's about 5 different 26" sizes that vary considerably in diameter.

Im sory the tubes say 27 x 1-1/4" so will they fit the 700 x 35 and 700 x 38 tire

Bill Kapaun

Yep

I broke my own rules and put used tubes that had been in 700x35 tires into a pair of new 700x32's, the tubes were quite stretched out and I had a hard time getting them to stay in the smaller tire. other than that, you can get away with quite a lot. most tubes are designed for a pretty wide range of tire sizes. absolutely critical however, is not using the wrong valve type. a presto valve inner tube should not be used in a rim drilled for shrader valves, and a shrader valve simply won't fit into the hole for a presto.

Cheap adaptors are made where you can use presto valve tubes on schrader valve rims.

Bill Kapaun

Presto?
Try Presta-
