Tire Pressure?

I'm a new 2013 Tiffin Allegro Owner, Model 31SA. Knowledge is good but sometimes it comes at the expense of feeling like one's on overload.

I'd like to hear from others what tire pressure you've been running on this model. I'm aware of weighing, etc. but am interested in hearing what others have settled into regarding Michelin tire pressures on this model.

Look on the label in the side of the entry doorway, Tiffin put all the data there, including the tire pressures ... in our case 120 front, 110 for drive and tag. It's based on their weight of the MH, but it's a good number to start with, until you can get it weighed.

Hope this helps.

If its second hand , probably former owner chached tires to a higher load-kind ( fi D to E load) .E load needs higher pressure for the same load then D-load .
So the advices on the sticker somewhere on the car can be for the original tires.
For that reason its better to re-calculate with my Motorhome-tire-pressure-calculator.
In this map download the newest version by RIGHTclicking and then choose Download from the dropdownbox.
If you cant work it out , Give GAWR's and tires maximum load and load-letter or "maximum load xxxx lbs AT yyy psi(cold)" and I will do it for you and procuce a picture of it in my answering post.

My 2012 Tiffin 28BR came through from the factory with all tire pressures in the 80's, 84,85 87 etc. marked with chalk. I have 265/70R 19.5" Michelins. The lower the pressure the better the ride, but not always the safest, IMHO. My tires say 110PSI cold on the sidewall.

I run all six of my tires at 95PSI plus or minus a lb. before starting my trip. As i'm driving, my pressure may increase to a max. of 112 PSI. I haven't had any issues driving this way. The ride may notice more bumps, but better mileage, less tire wear. I check each tire about every hour as i'm driving with the remote sensors. 215 HP diesel pusher averaging 13.9 MPG. Just adding my opinion.
