We're taking delivery on a new 2015 in a few days.

I know weighing is the preferred method of determining tire pressure but what have others with this model ended up using for best handling?

Thanks,
Cass

We took delivery on 4-3-15 of our 32SA. Had it four corner weighed two weeks later. Tiffin had 110psi in all tires. After weighing, I could have dropped down to 75psi in all 6 tires but it is recommended that you do not go any lower than 75% of the maximum tire pressure. Max pressure on the 255/80R 22.5 tires is 110psi. So the very lowest you should go would be 82.5psi. I run 90psi to give myself a safety margin in case we have extra people or added cargo. Right away it made a big difference in ride and handling.

I've tried to run 100 psi and haven't had any problem. I had the MH front end alinged after we got it with 6,400 miles on it. Truck place put 110 lbs in all the tires. I've run another 7,000 miles and 100 lbs. seems to be fine. Dave

We had our 32SA Weighed with holding tanks 1/2 full and with the weight they recommended running 90 lbs chart showed 85 but they said if you add additional weight your safe
