I have seen a few post on the toyos. I am a fan of toyos but I noticed this new set I have says 125psi cold. But the dealer only put about 95psi? What should I run in them to get the best performance? 2003 DS 42ft Dp

Tire pressure.. I am fond of saying there are 3 pressures that are all but guaranteed to be WRONG (Note.. sometimes one of them is right but that is kind of rare)
The pressure on the tire.. Read the FULL SENTENCE not just 125psi Max
It says something like Maximum load of xxxxx pounds at maximum pressure of 125 PSI.. This implies if the rig is lighter on that corner.. The pressure should be as well (TRUTH) thus odds 125 is right are low. but not impossible

The pressure the store puts in is the "Standard" they put in that tire unless you specify otherwise. Thus the odds of it being right. also LOW.

Somewhere in your rv is a sticker.. They make some serious assumptions as to how much you will carry.. Thus the odds of it being right are LOW.

How to find the right pressure

Scale it.. You can go to RVSAfety.com and follow the links and for a fee they come out and weigh all 4 corners and tell you what is right (This is by far the easiest way)

Or you can find a FLAT (not a bridge scale) Segmented scale (Most CAT scales are Bridge scales) park on it so each axle is on a segment by itself get the axle weights.
Then park so only one side gets scaled and get the wheel weights

Some say you should use the same pressure both ends of an axle. I say use the pressure indicated by the load that wheel is carrying

NOTE there are two charts at the Tire Makers you can download
One is for single tires (Like the front)
one for Duals (The rear)
Sometimes that is two columns.

Many (Myself included) like to add5 PSI to the chart.

Hope this helps.
