MBS 2401 tire pressure?

Does anyone know off hand what the max COLD pressure is for the front and rear tires on this above unit? I ordered a TPMS and want to program it at home, so when we fly to our coach back east, I can save some time by having it programmed ahead of time.

Thank you.

On our 2012 MBS (Solera) the max (tire sidewall) pressure is 80 psi. Don't think this has changed since.

Thanks. I was finally able to find another thread on this topic - sure seems like there are a lot of varying opinions?

I guess I was hoping that there is one iron clad "this is what it should be"...

There are tire company tables showing recommended inflation level vs weight carried. Having your rig weighed, each corner, and using the table will give an inflation number (as I understand, round up and use high side number for the axle). Also, there are manufacturer inflation pressure numbers on the door jam.
You asked for max cold inflation pressure - that is the tire sidewall max pressure (80 psi, on mine). That pressure gives the highest load carrying capacity for the tire. Lower inflation will give less load carrying capacity, per the tire company table mentioned above.

Here is a link to Michelin's tire pressure vs load table. My MBS uses L215/85R16 E tires.

Thank you. My concern - is that 61 PSI for the chassis or with the "home" on it as well? I'll see if I can get my old brain to figure out some of these charts and see what they say.

Thanks for the pic though - that's the kind of thing I can understand!

Sprinter tire pressure

I have 24,000 miles on the original Continental tires on my Prism LE2150, have always kept the tires at 61psi per the door and they are wearing quite evenly without any issues. I have rotated the tires every 5,000 miles. Before using maximum pressures I would be interested to know what 80psi does to the ride and whether it wears out the center of the tread before the edges? At 61psi the ride is quite smooth and handling seems stable and wear seems even. I don't think there is any safety issue with higher pressures, they should run cooler and flex less. Considering that with a Sprinter based motorhome most people are close to or over the maximum weight suggested for the vehicle I definitely would not run any lower pressures.
