The rim will definitely come into play as well. I bought Specialized 38s and on
a Velocity Dyad they would not fit without some rubbing. Schwalbe 35s was what I
settled on with fenders. I should say that I was not trying to run fenders with
the 38s.

barely fit and the rubber nubs at the side of the tires started wearing on my
stays and fork so I took them off. Since then I've been running Nimbus 38c
tires. I find Specialized tires to generally measure wider than their
advertised width so with another brand you may be able to exceed 38c.
