Thanks for the suggestions all. What's interesting is that you listed both the Conti 4 Seasons and Schwalbe Marathon Plus as tires you didn't like. Those 2 were also on my list of possibilities. I currently ride on 23mm 4000s. Maybe i'll give the 25mm 4000s tires a try and run them at lower pressures. I currently ride mine at 95psi front and rear. Any suggestions for tire psi if i got the 25mm for rain? I'm 141lbs so I can get away with the lower tire pressures.
