What tables are being referred to

Sorry to resurrect this thread..but the discussion is pertinent to another of my newbee needs: on my list of "things to pay attention to on my new DP" is tire pressures. I follow the discussion in the thread...BUT....where are the tables that are being referred to typically located?? MFG's websites?? (sorry I am not more specific about my needs...I do not have the manuals in front of me right now). Pending my getting the time to weigh my unit....people are mentioning using 100psi. Is that considered a "safe" starting pressure to use pending more weight information? (or is this strictly tire dependent......???????

Yep, answered your own question. Go to the RV tire section for each manufacturer and the inflation tables you need are there.

Nope, and moreover, absolutely NOT. If you MUST start someplace use the sidewall pressure until you weigh. IF, and only IF the tires are the same brand/size as originally installed, use the manufacturer label inside the moho.

I have Michelin 275/80/R 22.5 XZA 3 tires. If i have used the Michelin tire weight info on the internet correctly, I assume to get proper front tire pressure, I divide the FRONT by 2 and BACK by 4?

I do not have a TAG AXEL.

If i do this, I come up with about 80 psi per tire which seems really low to me. I have been running about 105 psi, is this too high? I note max pressure cold for the tires is not to exceed 120 psi.
I'm not surprised on your steer axle -- you have a lot of tire on there for the weight -- not that it's a bad thing.

LRG and LRH refer to the Load Range of the tire. They each have their own load/pressure chart. It doesn't refer to non XZE or XZE. The LRH will have a higher capacity than the LRG.

Yep, and we still don't know WHICH tire they have installed - or even if that poster knows the difference.
