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?
Thanks for the info.
The tires are 700 x 32's
I found that on my 700 x 32 Gatorskins I lowered the pressure to 60 psi and had a noticeable improvement with a softer ride on our rough pavement in our area. I would like to run a little lower pressure on the MP's too. I know I can't get too carried away but there is a happy medium there somewhere. Curious what pressure others are using with these tires.........................
