I’d expect both of your tubes to be the same irrespective of the difference in tyre width front to back. The 1.95 on the front will be fine. Personally I’d fit new tubes as they’re cheap enough. When you fit the tyre(s) make sure the bead is seated properly. My 29er seems to take several inflate/deflate operations to get the tyre seated properly.
