Thanks for the great feedback regarding the air compressor.
I would get a 12v rather than a 120V air compressor. I know some folks have inverters for their RVs or have 120V outlets in their tow vehicles. Given limited access to 120V outlets when out on the road, I am go to go with a 12v unit. I can get one that plugs into a 12v outlet or one that clips to my tow vehicle's battery
. I am thinking the one that clips to a battery would be more robust, particularly with the engine running. Of course, I will have to determine if the hose would reach the trailer tires or if I would need a longer hose.
It looks like several of you like your Viair units. Nice! However, others have other units that you like as well. I have read good reviews on some of the Slime units.
Regarding my tire pressure at 80 lbs., here is a quick summary:
1. When we got our new to us Casita
, the tires were 6 years old. The Casita
had the standard size wheels that came on a '05 Casita (14" rims). I was hoping to get one season of use out of the tires. LOOKED fine in terms of tread and no cracking. D'oh!
2. After our first trip out of town (460 mile round trip to the Smoky Mts), the tires were shot. I was lucky to get home without two blowouts. The old tires were 6 ply and C rated with a max psi of 65. From what I can tell, they were good tires. They were just old.
3. So I did my typical, I started researching. I noticed that Casita now offers 15" wheels on their trailers, which used to be their optional wheel.
4. I also noticed that I could get more variety in tires for 15" wheels in terms of number of plies and load rating.
5. So, I went to Trailer World and bought three 15" wheels.
6. I then went to my favorite auto shop/tire dealer and spoke with them about new ST tires. By going with the 15" tires, I upgraded to 10 plies rather than 6 and they were E rated rather than C rated. In addition, the max psi for the tire is 80 lbs.
7. There seems to be lots of opinions on how much pressure to put in a tire whether a car tire or a trailer tire.
8. I attended the RV Safety and Educational Foundation conference in May. Very cool. Walter Cannon was one the main facilitators at the conference. He is a tire safety guru. What I gleaned from the conference is that a tire is designed to be run at maximum psi. In terms of the tire pressure going up after it is warm, it will, but the manufacturer builds this capacity into the tire. I have not been running 80 psi in the tires, but I have chosen to keep them at around 76 psi (95% of max).
So the reason I want an air compressor that can easily handle 80 psi is because my tires are rated at 80 psi max.
I will keep ya posted on the air compressor.
