I suppose this means P rated, P275/60R20
So you fill back ones to 40ish when towing and leave front at 32?
For some reason I thought if you didn't have the tires inflated to where they were suppose to be, they wouldn't wear correctly?
I always inflate my boat and campers tires to what they list as Max PSI because I was told to do that.
Not very mechanical....can you tell :)
My door sticker says 30 in front, 35 in back. My Firestone Destination LEs are great tires but are softer than other tires I've owned. I tend to keep 2-3 psi extra in them at all times. They seem to wear much better. For towing I put 5 psi extra all the way around. 35psi in front, 40 in back.
Trailer tires are always aired up to their max psi listed on the sidewall. Even my HTT manual tells me to do that. Vehicles are an entirely different matter. Weight changes how they behave. So yes, in theory, running at psis outside of the recommended can produce abnormal wear. Its a matter of experimenting a bit.
