Switching mtb tyre width implications

    Just wondering. I'm currently running 26 X 1.5s on a tandem. Is there any reason to think a switch to 26 X 1.35s will do any more than:

    a) slightly reduce rolling resistance?
    b) reduce the longevity of the tyre?

    I'm happy with both a) and b) but is there any other reason to think I shouldn't make that switch?

    I'm not sure , that rolling resistance will be reduced.
    C) The comfort of the stoker will be reduced.

    With the weight of a tandem plus two riders the wider tyre allows for running lower pressure and hence more comfort...
    It's never going to be quick...

    Thanks. In truth, reducing rolling resistance isn't a priority, more an unintended (but welcome) consequence. The point about comfort is important though. However, the stoker in this case is a 7-year old so the weight distribution leans towards the front and I'm guessing that any decline in comfort will be almost neglible as a consequence. Am I right?

    I should also say: although not impossible to find, 26 X 1.5s are slightly unusual and I'd have more more choice in either 26 X 1.35s or 26 X 1.75s.

    You're wrong about weight distribution.
    The stoker is is pretty much over the rear wheel and therefore takes a lot of the shocks. The pilot, on the other hand is between the wheels, and is therefore less shaken about.

    These tyres are really good, they roll very well. Available in 1.3 and 1.6

    They maybe available elsewhere at a better price.
