I wish I could believe that. I didn't check that closely when I picked the bike up as I assumed the LBS was competent, and it's true that I could have missed something.
On the other hand, the online quote of a max of 70 psi is more in line w/ charts of Sheldon Brown, the tire *does* seem a bit loose on the rim, and I *am* a heavy guy.
On the third hand, Sheldon's pages also state that blowout limits are usually a factor of two low, so I would think that putting 85 in a tire rated at 70 should be ok.
