Ok, so granted I am not the heaviest brick in the load so thought I'd ask this question. It might be simple logic but I want to be sure. My RV tires are to be at 130PSI front and 120PSI rear.My air compressor states that it has a maximum pressure or 150PSI tank pressure. So,if this is running properly it should fill the tires to their respective pressures. Right? Should I assume that since the tire pressure is to be 130 and the max pressure from the compressor is 150 then the amount added is only 20PSI and it a very slow rate??Or should I get a higher PSI capacity air compressor to do the job?

What is the CFM of the compressor?

Kind of shocked that you have to carry that much pressure.What tires and what wheel/axle weights???

Been called a brick by my wife before and not in a nice way either.....The CFM of your compressor will determine how long it takes to fill a tire. A low CFM means you might have to shave and shower between tire fills.Whatever the CFM is, get a pressure regulator and set it for the desired pressure and install that between the compressor and the air chuck. That will get you close without having to 'babysit' the process.You sure about those pressures? Even commercial truck radials only fill to 105 psi.

Yes 130 sounds high.If it is a small compressor with a small tank it will take awhile as compared to a tire shop compressor with a huge tank with lots of volume. Most of the large compressors of that size won't go higher than 150 lbs.

I carry 120 psi in my steer tires and it seems like it wouldn't go much beyond that. But I agree with others 130 seems too high. Have you weighed the coach yet?
