I called the tire manufacturer for my new tires. They said absolutely you can run under 50 psi in load range E tires. They said to refer to the tire and rim association load and inflation tables which also show load rates for inflation pressures as low as 25 psi for load range E 10 ply tires. I have this table and found it again on the internet to confirm it.
Some tire manufacturers publish documents showing what they determined to be the proper air pressure for their particular tires to meet OEM standards. They use the tire and rim association table as a starting point to make their determination for their specific tires. These are interesting to look at.
Anyway. I am satisfied, based on the above information, that I can safely run lower than 50 psi on my new tires.
Do you have a link to this table? Their website looks like you have to pay for any info obtained.
