I've got 26x1.9" tires on there. I think i ran them about 50psi for that trip. I figured it'd be a decent balance of cushiness and ride quality. The tires I've got on there aren't that great. Some cheapo, heavy Geaxs tires. I'd really like to upgrade to some Schwalbe Marathon Supremes when i get the cash, but that could be a little while.
