Commuters need Goldilocks tyres; not to wide, not too narrow.
I use the same set all year round, and expect rain at any time.

For 700C I reckon 25 to 32 mm width is suitable. For 26"mtbs, a 1.25" to 1.75" should be sufficient.

I ride 700cx28mm and find it a good balance of speed, comfort and reliability.
