Tire Inflation Guide
Can anyone tell me where I can find a chart telling what pressure I should run for the axle weights that I have? Thanks

A couple of thoughts:
First, the maximum pressure listed on the sidewall of tires is a COLD pressure - and the tire is designed to accommodate pressure build up many times what is normal.
In other words, you don't need to worry about allowing for pressure build up. It's already taken care on and you can inflate a tire to its maximum without fear.
Second, a lot has happen since the Ford/Firestone thing a few years ago (year 2000). All the motor vehicle manufacturers have addressed the tire sizing thing by 2008.
However trailer manufacturers are hit and miss. Some have, some haven't. That may be one of the reasons we have such contentious tire threads. We are dealing with vehicles that are marginal on tires.
And lastly - chalk method? Not a fan, because it assumes that a properly inflated tire has a good footprint and over and under have bad ones. That's not a very good assumption. Many tires contact patches don't change much due to pressure (other than length).
Besides, tire wear is more controlled by the vehicle and the way it is used, and not inflation pressure.
A better way is to use pressure buildup. Target is under a 10% pressure buildup. Between 10% and 15%, it should be monitored and adjusted if it continues to be at this level. Over 15%! Immediately stop and do something. Add air, slow down, get a larger capacity tire.
