It has become evident that tires, not wheels that will determine your ride.
I would find out what the widest width tires your bike can take and go from there. Wider tires have now been proven in both lab and real world to have lower rolling resistance, puncture resistance, more compliant ride (lower PSI) and in many instances, more aero.
- The aero benefits seem to be dependent on your wheels though. Really wide tires from Zipp and ENVE are most aero with 28mm tires.
- I haven't done the tests, but, I would think on my 23.5mm wide wheels, 25mm tires are better than 28mm tires. I believe Zipp and ENVE are now making 25mm and wider wheels for 28mm tires.
