Don't know about the 2.35's but I heard this when I was buying my minions and got the 2.5's cause everyone said they are the size of kenda 2.3's. The 2.5's turned out to be only a tad bit bigger than my Specialized 2.3's
A Maxxis 2.7 doesn't even measure to a 2.5. This is pretty much true of their entire tire line.
I'll go you one sicker.
I put a Minion DHR 2.7 SuperTacky on the back of my bike in mid Sept (Sun Singletrack 31mm wide rim). Something was off, but I couldn't put my finger on it.
Then I measured it against the back tire on my AM wheels that had a Minion DHR Single-Ply 2.5 on a Stan's Flow rim (28mm wide).
The DH tire was run with a 2.5mm kenda DH tube, the AM tire was run tubeless. I measured both at 25 psi. The single-ply tire came in about 58mm wide and the 2-ply DDH tire at about 53mm. I double-checked after a couple rides and this didn't change.
This puts the DHR 2.5 at about 2.2-ish size, and the DHR 2.7 *smaller* than that.
On the other hand, I'm pretty sure Specialized tires run a little big. They have with road tires in the past, at least (700x23 was actually even wider than a normal 25) Can't say anything about how they are now.
