Pressure is tied to the tire size. A 28mm tire is getting sploogie at 80posi. A 35mm tire at 80psi is just fine. What size Marathon Plus do you intend to use? Why do you want to use the lowest pressure you can use? With a tire that has such a high rolling resistance as the MP you should want to use the highest pressure you can use. That pressure is printed on the sidewall. If you want a more comfortable ride, get a more compliant seat or seatpost. For tires to make any difference to comfort you need 2.0+" tires with 25psi to 30psi. Do MP's come in 50mm?
