I’m at 85-90 on my 23mm tires and tried looking for guidance on how low to go for wider 33 and 42mm tires. I’ve found everything from 15-50 PSI and rim has max rating of 80 and tires say between 50-80 for 42mm tires. That seems very high. I was thinking 30ish but don’t want to go below tire rating. 50 feels hard. Very hard. Should I go lower despite the tire rating? You’d think the tire guys would understand the tire pressure game.

Suggestions for 33’s as well?

I’ve lunch flatted on my road rims at 80 which is why I stay at 85-90. Road is also tubed so not quite same situation.
