What size and type of tyres did you use, out of interest?
I used Marathon 25's on the rear and a vittoria Randonneur 25 on the front. I got through a couple of rear tyres before i changed the front. I bought 2 marathon 25's at that point. Quickly found out that the marathon rubbed on the mudguard on the front and had to drop the wheel within the dropout. Got rid of the mudguard, luckily it worked out ok.
Cannot fault the tyres, no punctures with them.
One problem was when i changed the tyre to a gatorskin. Going down a hill in a rainstorm, hit some debris and split the sidewall.
