HI,

I have Goodyear G661 HSA 255/70 R/22.5 load range H tires. I'm trying to find the right pressure. My steer tire have 4210# and 3820# rear on each of the 4 tires. This comes from the cat scale. I can't find my tire chart. I found a couple of others similar and I have come up with 85# for the front and 80# for the rears.

I know some fill to max but I also have learned that is not the right thing to do. If anyone knows where I can find a inflation guide or the correct pressure I would appreciate it.

Thanks as always

“I also have learned that is not the right thing to do”

If you don’t need the tires maximum weight carrying ability. What does the RV manufacturer and the tire manufacturer say?

Seems this chart shows the sidewall numbers for the tires, Not what to use by weight.

Normally there's a tag somewhere in the motorhome with pressure specs.
