Some of you may have seen the thread I started outlining the problems I had with a set of Schwalbe Ultremos in size 28mm. It's here in case you missed it:
Now I'm really confused..... 28mm tire on 23mm rim..... Not compatible???
Unfortunately the way Schwalbe manufacturers the bead on their tires, they would not work on my 23mm (ID) rims (See above link for explanation). So I'm looking for a tire that is similar in performance, durability, and weight to the Ultremos but do not want a tire that is spec'd at larger than 28mm. So I'm looking for a tire that the manufacturer rates as a 28mm but is actually larger when mounted.
I tried mounting a Hutchinson Equinox in a 25mm as an experiment (because Schwalbe told me a 28mm was too small for my rim and that's why they kept coming off the rim at the bead) and found it to be 28.5mm on my rim.
So what what tires can I look at that are actually larger than the manufacturer's spec's? I'm looking for slick tires only please. Nothing with a visible tread. I originally chose the Ultremos because from everything I had read about them, they were actually closer to 31mm when mounted.
