Air pressure multiplier

The Les Schwab tire store in Junction City is selling an "Air Pressure Multilier" that they claim will double the incoming air and bring you tires up to pressure much faster and easier.

Has anybody had any experience with this product?

Thanks for your input.
Jim

I did talk to Paul in Junction City about it and did quite a bit of research. I needed to get my fronts up to 130 and was having trouble . The system does work but is very expensive. Newell coach also sells a similiar system which works as well. I opted for the Viair 450 compressor which works well for us , is small and portable , no need to start the coach and allows me to help others if in need. 2-300 dollars depending where you shop plus an extra 25 foot hose. We got ours at desert rat off road in Mesa.

Its a great product and I have owned mine for 4 years. For those of us who are supposed to have 120 ips up front its the only way to go. It will raise a 12R or a 315 from 105 to 120 in about a minute. Its small and convenient. Yes, it pricy, but such a good product.

I bought one from Schwab about three years ago and it has worked as advertised. I mounted it and plumbed it permanently in my front drivers side compartment. It is a little slow on the front tires to #120 but very compact and convenient to use.

I bought one of the CO2 tank systems before knowing about the multipliers. It is very fast, can exceed 130psi easily and it's easy to find places to get it filled. But it is heavy and large in comparison to the multiplier.. Does qualify as another option.

Jim,

I have the multiplier from Schwab and it does a great job. For me, I'm adjusting the air pressure for altitude mostly and it doesn't take much time. I too run my fronts at 130 psi.

Jim, you said "adjusting the air pressure for altitude ." Can you explain the rational for doing that?

Inquiring minds need to know.

Lee,

Let me preface this by saying I try to keep my tire pressures close to the recommended settings even if it is only off 3-5 psi. We are full timers and usually spend the winter in Arizona and travel to cooler climes in the summers. Our stops are typically 1-2 weeks when we are traveling. I check the tire pressures in the morning the day before or the day of our move to the next spot.
When we move from the higher elevations to the lower areas, I have to add air to the tires. The elevation change has to be significant for this to happen. For example, we were in southern Colorado in early October and then went to Casa Grande, AZ. Pagosa Springs is at 7100' elevation and Casa Grande is at 1400' elevation. The difference in atmospheric pressure is right at 3 psi. This means if you checked your tires when the outside temperature was the same in both places you would have to add 3 psi to bring them back up to what they were in Pagosa Springs. The morning after we arrived here I added air to all our tires. Since temperature of the tire is a big factor in what reading you get, I always check mine early before the sun has a chance to warm the tires.
Now we could debate whether all this is necessary for 3 psi. For me this 3 psi, added to the normal loss of air pressure that always occurs, is important. And before anyone asks, because of this normal loss of air pressure and our apparent gradual rise in elevation of our travels, I have not let out any air when going from low to high elevation.

Having the Schwab multiplier makes this adjustment process easy.

One year while at Les Schwab having my 275R 70's replaced on my Previous Allure with 275R 80's I asked about tire pressure. I got the story about measuring in the morning! But when when pressed the answer was 68 F degrees. If you live where it is in the 30's in the morning measuring your tires will give you totally the wrong pressure. So I try to measure my tires when in the shade when the temp is close 68 degrees. During this time of the year for me its during mid day when the sun high over head.
