So, I'm not sure where any of this discussion leaves us.. We have an OP who weighs 190, but with 32mm tires that indicate max of 70psi. We have HED who'd recommend 55-60psi. We have Schwalbe chart who'd generally recommend somewhere around 85psi, and Cypress's calculations around 80psi. Tire inflation calculators seem to indicate a rear inflation somewhere in the 70s. Someone quoted Hunt wheels max of 50psi for 33mm. These don't seem like small disparities.
