Not sure but I run 40 in mine but not a low profile. 32 psi seems low to me

Tab included a card inside my Diamond Back Metz 120-70-21.On the back were some notes.Here they are word for word. 120-70-21 ME 880, Max Load= 584 lbs , Max PSI=42 PSI Cold, Keep at or near Max PSI ** AT ALL TIMES** And here are the recommended tire pressures direct from the Metzler Web site: Me 880 Front Tire. Solo 38-40 psi, 2 Up light 40-42 psi, 2 up heavy 40-42 psi. I run my DB 120-70-21 @ 40 psi cold.

Mezeler 40-42. At 32 you will wear that tire out in a very low mileage. I don't know fi u can still read what it says on the sidewall, but i always run it towards the high range of the pressure that is recommended.

I've never seen a tire that didn't show the max pressure on the sidewall. It's a good rule of thumb to never run less than 2-4 lbs below the max pressure stated on the tire. People who are saying 40-42 are probably correct, but I would never take someone's word for it; I would check what it says on the tire.
