Actually, I was trying to say I reduce pressure to improve the ride of my trailer also. I provided the formula as a way to determine approx load carrying capacity when cold px is reduced. 80 psi taken down to 70 psi is only a 12.5% reduction. Any lower than about 65psi (nearly 20%) and tire life is degraded a bunch (around 10-15%, IIRC).
A consistent 10% to 12% px redux only reduces the lifetime of the tire by about 5%. I think it's worth the reduced wear and tear on the trailer.
