Use RV tires at 110 PSI compare Viair models 450 P and 400 P RV? The model 450 appears to be more robust. Comments?

I have the 400PRV, works for me, but I am only inflating to 95lbs. Haven't had any problems with it doing what it is supposed to do.

I have the 400P and have not had any problem bringing my psi up to levels. I did have to run the pressure over my goal so I don't lose too much disconnecting.

I pull a big 5th wheel with a 350 Ford. I run 70 PSI in the front and 75 in the rear on the Ford. Have 110 PSI on the 5th wheel. This little compressor does a good job of helping me keep my tire inflated to the correct PSI. It easy to operate and bag it comes in makes it easy store in the Fords tool box. If I were going to buy a need small compressor I would buy this one.

While I have no exact information as to the components used inside the two different models, the 450 at first appears more robust because of its advertised "100% duty cycle", suggesting that it can be run continuously. However, if you read the specs on the Viair web site, you'll find that the 450 draws less power than the 400 and puts out less air ( at 100 PSI, 450P - .94 CFM vs. 400P - 1.27 CFM ). I would say that while the 450P can run longer, the 400P can put out more air in the time it can be run before it needs to be shut down to cool. So if you expect to fill one flat tire or four smaller ones on a non-modified 4x4, the 400P will get the job done more quickly. If you're planning on filling up four 37's on your lifted 4x4, the 450P might be a better choice. It will take longer, but the 400P might need to be shut down to cool before it gets the job done, while the 450P seems to be rated to keep working until the job is done. The other thing I would mention is that each model comes with slightly different accessories. The 450 has a single length of hose, for use on a shorter vehicle, like a typical 4x4, where you don't need to go as far to reach the farthest tire from the battery. The 400P-RV has a double length of hose, allowing you to reach farther for a longer vehicle and to stand farther away from a high pressure tire as it's inflating.

The company says that are 3 layers of 110 tpi each ! It seems a lot. Anyway, it is not a tire that will expend neither deform with max pressure 120lbs. The 4000s tire is a very good tire . The Vectran layer is good but it is not the best puncture layer I have seen.

This compressor is rated to 150psi. It will fill tires up to 37 inch tires. they usually have a maximum PSI of 120 pounds. This compressior has a continuos run time of 40 minutes straight and then you have to shut it down, to cool. so provided that your tires aren't completely flat, I see no problem with you filling up your RV TIRES.

It's really hard to tell. The TPM on truck will have 36 psi, Accutire says 34, My tire inflator says 38, Pencil gauge says 32. I use the accutire because it is easiest to read and seems to be at about the average of the other gauges. 2-4 psi difference is really not significant. I wouldn't know where to find an absolute accurate tire gauge.

Depends on the brand of tire but most run in the 90 to 120 psi range. Check the sidewall. The recommended psi will be there.

I usually use 28-31 psi for any motorcycle tires. Not to hard, not to soft...gteat grip and they heat up well

We used one of these for a heavy duty trailer, cant remember the tire size now but it was big. Worked fine but... its not the strongest material and I am waiting for it to give. My vehicles do spend a lot of time in serious off road conditions, that is why I worry. If this is for normal use, you will be fine.

Charles is correct but there is no simple answer. I would like to elaborate a bit further. The sticker on the pillar is/was correct for the original equipment tires given the following: 1-the exact size listed 2-for an average day temperature (0-90* F typically) 3-for the maximum weight listed So if you have an average car, on an average day, with tires that are of reasonable quailty, you should use the sticker on the door for the COLD inflation of your tires. Now, if the tires are a different size, you are traveling in extreme temperatures, and/or carrying at or near your maximum load rating, traveling long distances (in excess of 100 miles) or have poor quailty tires, your inflation will need to be adjusted for your conditions. This is because tires build up heat. The tires are designed for a certain amount of heat. When traveling in extreme conditions or with heavy loads, addtional air pressure is need to keep the tire from flexing too much. Too much flexing causes too much heat. This is why you see more tire treads and chunks on the freeway in the summer. So you ask, how much air to I add when I am in those "extreme" conditions. The answer sadly is that only the tire company's "load inflation table" can tell you. Every tire is different and every car, truck, trailer and RV is loaded differently. Each vehicle will need to be evaluated to what trip is, how much weight are you carrying, and the conditions expected. When we go on a family vacation, and have the vehicle "loaded up", we inflate closer to the tire's sidewall maximum PSI just to be safe. Regular day to day use of the vehicle, we run closer to the door pillar "sticker" weight.

I think the volune is what is important. I can inflate the tires on my jeep which are. 30x9.50 which is a large tire. All four from 22lbs to 28 in Less than ten minutes. This allows me to run off road with low pressures and re inflate for the highway. I was told I may need to spend over $200 to get one that would serve my needs. I used it for four months in Colorado almost every day. It is still functioning well. Hopes this helps. .

I have generally kept mine at around 95 psi without issue. That's with the stock tires and tubes.

That would be a 4 ply tire. 113T is the load index and sped rating. 2535lbs per tire at max psi and 118 mph

I am not familiar with VIAIR however this product is very well made. I have had several mini compressors in the past and this one seems built to last.

No at all!, in my experience I use to pump up my tires at maximum recommended (85psi) in Michelin World Tour and I didn´t have problems, Of course I use the Michelin tube "Michelin Airstop" and "Avenir Threaded Presta 48Mm Valve Tube"... The Tuffy Bicycle protection is great for ride for everywhere...

I can never go above 2. Living in a RV and limited to 400 SQ ft, 5 would run me out besides using to much gas for no reason. A 25 lb TANK WOULD LAST ME FOR SEVERAL MONTHS as many in this park are using.

For me, 25mm provides a better ride. I also inflate them to a lower psi than what is recommended. I run the rear tire at 90 psi and the front at 90psi. I think that set up provides me a better ride especially on roads that have been chip sealed. Mike

I'm 220 and no problem, running recommended pressure on the side wall.They should have a higher capacity than skinnier tires as far as weight cap.

Hi. I own this trailer, and used the 45 mph rated tires for a bit, but stayed 55 or under. I bought the higher rated tires anyway, knowing I would be doing higher speeds. Have since traveled at 75 mph with no problem. I carry the original tires as spares.
