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

The sticker besides the driver’s seat is the psi IF the axle is loaded to its MAX… go weigh and set accordingly. While the OP may weigh close to the max on the front and assuming a tag the 6 on the rear will be less than 100 psi.
This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.

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.
Home was where I park it. but alas the.

When I got my Toyos the installer put 110psi in them without my knowledge. The thing rode like a rock. After I found they were at 110 I checked the Toyo web site and it actually said to use the Michelin inflation chart which stated for my weight I should run 95 front and 85 rear. Rides nice now.


Love my Falkens made by Sumo. Falken told me to use the values on the Motorhome wall (115F; 95R). I'll compare that with the Michelin chart.

Check the placard on the wall under the window next to the drivers side seat. It will detail recommended tire pressures for the front and rear axel's tires. Set your new tires at these until such time that you weigh your coach to determine the manufacturer's recommendations. I highly doubt it will be as high as 125 psi.

Just about any tire pressure chart for your tire size will provide the pressure required to support your MH’s weight. Use your GAWR to determine pressures until you get actual weights, or pressures displayed in your unit. The numbers on the tire are your last resort pressures and rarely required on a MH.

Best performance and best ride will most likely require different values!

You need to weigh your rig, then use the tire inflation chart to set the pressure. Use a Toyo one for a Toyo, otherwise until you can have it weighed use the placarded pressures provided by the manufacturer. Last resort is using the max pressure.
