Anyone with a 36CKTS or similar weight RV have any info on what pressure you are maintaining? Also do you try to keep it Nitrogen pure or do a mix to simply add a few pounds of pressure?
The tire pressure is weight dependant. Here is a link to the specs for the G614's which came on my 36CKTS. You may have different tires.
Next is the nitrogen. Air is mostly nitrogen anyway. Your tires are not "pure" and never will be. Just add air.
Now the age old discussion. There are basically three theories.
1. Use the correct pressure for the weight.
2. Inflate to max cold psi. (aka blow hard)
3. Go by looks of the sidewall or hit em with a hammer.
I used the chart +10% along with a good tpms (TST) because I only had axle weights and not individual wheel weights and also the load varies a bit. That was 92 psi for me.
If you have ST tires just use the blow hard method.
Hope this helps. Tireman9 may have something to add to this...
