Do these tires run big? I got a 28c to go on my Leader S803 fork, but it's rubbing a bit on the crown fork. It's barely rubbing, in fact it's really just the extra rubber sticking up the middle of the tire that's rubbing, but it's still a little too close for comfort. My question is whether I'd have better luck with a different 28c tire, such as a Randonneur.

And, for part two of my question, would I be better off with two 28c Randos or a 28c hardshell in back as a 25c hardshell up front. My main concern about the Randos are the low psi rating. I'm a bigger guy (250lbs) and am not sure if I'd be better off with a higher psi tire like the Hardshell in a 25c size, or a wider 28c tire that has lower psi like the Rando.
