Time Trial/ Tri Aero Wheels Query
With the exception of a very few wheels that have a low maximum rider weight, the only real reasons not to use your TT wheels all the time are:


Cost - do you want the daily road grime all over your $2,500 carbon wheels?
Surface area - cross winds when your rolling >80mm dishes can become interesting
Braking surface - related to (1)...you will eventually wear down the braking surface.
Flats - these days a lot of TT wheels are clinchers, but if yours are tubular, carrying a spare tire all the time may not be ideal. For more than a race, you'll need to really protect the glue.


I might add a (5) that some people will think you are a poser with more money than talent...but I personally think rolling around in some deep carbon is cool.

The few wheels that have the low max weight could fall apart as they get beaten on the bumps and dips of daily riding, the vast majority are probably just about as strong as (or possibly stronger than) the wheels you are rolling right now.

Happy Riding.
