85psi is the max recommended pressure on the tire, and i'm used to riding on my road bike with 23's @ 130psi, so i like to keep as much air in the sport contacts as they'll safely take. as i said before, one of the reasons i'm contemplating a carbon fork is so that i can hopefully drop down to a 32 or 28 with a 100+psi rating.




perhaps it would be more comfortable, but i have found that, for any given tire, on a reasonably well-paved surface, that keeping the tire at max pressure is always faster than going with a lower psi. spongy tires are an energy suck on smooth paved surfaces.
