My husband, Gustav, and I are very new to RV living and jumped into it with both feet full-time. We bought a 2008 Fleetwood Southwind 36D with low miles 11 April of this year. Immediately, we drove it (pulling our toad) about 90 miles to the location of our RVdrivingschool instructor's farm in western NC, Paul Nordan. Best money we spent as he helped us gain some confidence in driving before tackling I-70 heading north through VA and WV to OH. Now we are in TX where we have been enjoying time near our three grandchildren (and their parents). Still getting used to the lifestyle and all that goes into care and maintaining our rig.
Question: we have purchased a TPMS and have read some of the posts on here concerning tire pressure. We have not weighed our rig, yet, so only have the sticker inside the coach which recommends 95 psi for the front tires and 90 psi for the rear. There are new tires on the rig as of last August 2016 put on by the dealer for the previous owner which recommend 110 psi on the sidewall. Which is best at this point to use for psi? And how does one know what to set the temperature limits at? We have 22.5" tires.
Thanks for any help with this.

Well my response doesn't make as much sense when the response to which I was referring is deleted. Doesn't change the info, but someone coming to this without the context would probably wonder what was going on. The deleted post made reference to wheel by wheel weighing, and other 5th wheel and trailer stuff regarding tire pressures ... not realizing that the OP was in a motor home.
Not to confuse things too much, but tires on 5th wheel trailer's and tires on motor homes are a little different. Your motor home manufacturer has published tire pressures for YOUR motor home's GVWR. It assumes you are not overloaded and further, the tires on the rear are probably dually's, so their combined weight carrying capacity exceeds the rating of your rear axle. In short ... follow your manufacturer's recommendation for tire pressure IN YOUR MOTOR HOME. On trailer's it's an entirely different discussion.
On my truck (a 2016 Ford F-350 DRW), the tires have a maximum pressure of 80 psi embossed on the sidewall. The Manufacturer recommends 75 psi on the front tires and 65 on the rear dually's. It's like your motor home. The tires, inflated to the recommended pressures carrying capacity exceed the axles rating both front and rear. So I use those recommended, as should you.
As for temperature settings, Michelin says that tires fail due to high temperature at between 180-200 degrees Farenheight. My TPMS manufacturer recommends setting the high temp alarm at 158 F. As for pressures, they recommend low alarm be set at 10 psi below the cold temperature pressure and the high pressure be set at 20 psi above the cold temperature pressure setting. Hope this is helpful.
Be Safe!
