Hi Mike,
Are the “old rims” tubeless compatible? If not, I’d be wary of running less than you would with a tube since there is no architecture in the rim like a head lock or shelf to accommodate the movement of the tire without the support of the tube. Yes tubeless ready tires are stiffer in the sidewall but the bead isn’t pressed Into the rim by a tube which is how the rim was designed if it is not a tubeless ready rim...

Tire pressure calculator.

So far this is the best tire pressure calculator I have seen and used.   It very closely resembles the data I got from back in the days that we were all riding tubular tires and when I had a 
tubular tire repair business.   Sign up for access to the Pro version it is well worth the ability to add in the different variables.
