It affords up all 4 35 inch tires ... - I do allot of wheeling in my 2016 wrangler jk rubicon. I recently went to a 35 inch tire on beadlock wheels. Before I was running 32 inch tires on the stock wheels and airing down to between 18 and 20 psi. Well just the stock tires burnt my cheap little compressor up. Now I am airing down to 10 psi and this thing is amazing. It affords up all 4 35 inch tires up with no problem and I am not having to travel with low air pressie to a gas station. It's a great air pump and it airs up my tires in a fairly decent amount of time I think it takes about 4 minutes maybe less per tire. And I am not ruining them on pavement looking for a gas station to pump them back up. I would definitely recommend this to anyone who wants a good portable air compressor that wheels allot. Oh and it's very quiet too, which was shocking to me, as I was expecting it to be loud like my other small El cheapo compressor was. Do keep in mind though when using this one or any one like it always grab it by the handle. My nephew can attest that the metal parts get very hot, as all compressors will. Definitely a good buy and I will definitely buy again once this one gives out if I haven't gone to an onboard air system. Quick update. Can't say enough about this little air compressor. It does great on my 35Γ—12.5r17. Now for a real test. I got home with my 07 379exh peterbilt, and had a flat tire. This is a 295/75r22.5 that takes 110 psi. And in about 20 minutes it went from 0 psi to 85 psi. Is it the fastest way to air one up? Nope, but when it is all you habe at home it is great that it can do the job. Review: Well made compressor. - This is not the fastest out there, but it works very well. 100 percent duty cycle. Very quiet and so little vibration, so much so I was pleasantly surprised. All my other 12v compressors have been noisy, and shake like crazy. The carry bag is nice, the hose and all the accessories are well thought out. One of the situations where you get what you pay for, and I have grown tired of paying for junk. This should last a long time. Happy customer for sure. ## Features - 12 VOLT - 150PSI Max Working Pressure, engine must be running during use. - 1.80CFM Free Flow at 0 PSI. Air Hose: 35 feet.

You're looking to operate at the maximum edge of the pressure rating. It won't blow up per say, but it's not going to be as fast as you need. Look at Max psi closer to 200 psi with 100% duty cycle. **Q: Is this the best brand for this kind of portable compressor? Looking for most solid/reliable unit with no budget.** A: This is the best. **Q: Would it work if i replace the 12v clamps with longer wires / cigarette lighter (male)? so, i don't have to pop the hood open.** A: Willie, they're not full of crap, you've just been lucky and haven't run your compressor to a high enough PSI to draw full load amps (it will draw very few amps at 0 psi and max amps at max psi), or you've put a bigger fuse in your cigarette lighter, so you can draw amps until the wires melt under your dash and maybe catch on fire. If this compressor was safe to run on a lighter plug, it would come with the option just like the smaller viair compressors. If you're okay with the risk of a fire under your dash, and you wouldn't mind re-wiring anything that shares the routing through the dash with the lighter socket wires, then give it a try. You can extend the wire(s), but do it to the battery with about 10ga wire and a quick disconnect that insulates the battery end. Napa, or your local knowledgeable auto parts guy, can show you what you need if you give them this description. You can keep the clamp for the ground and find a nice bolt or bracket, then wire your hot near that. 10ga might be a little light on paper, but since you aren't combining it with other wires you won't overheat it. I would pick up an inline fuse (all-weather) and put it very close to the battery in case something shorts your wire, the fuse will blow instead of killing your battery or catching on fire. FYI, if you do make a cigarette plug adapter, the high resistance in the small wires under your dash will reduce the power available to your compressor so it will run slower (all that power reduction goes into heating the wire bundle in your dash; pure physics, and a bad idea). **Q: Can i run this off a car jump starter pack?** A: James,We recommend that you run our compressors with constant 13.8V, meaning a recharging car battery (vehicle on) or a converter/power supply for the compressors to operate as specs. Running our compressors with a jump starter or stand alone battery may not give the compressor the voltage that they may need. With low voltage, the compressor will be starving for power and create high amp draw or worst damage the compressor. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Now I am airing down to 10 psi and this thing is amazing.

Very quiet and so little vibration, so much so I was pleasantly surprised. All my other 12v compressors have been noisy, and shake like crazy.

Happy customer for sure. ### ⭐⭐⭐⭐⭐ Powerful, relatively quiet, and a pleasure to use *by A***R on 4 December 2020* When you buy something that really works well, it's always a rush of pleasure. This device is great. When weather turned cold, we had two cars with low tires, and the hose on my previous compressor fell apart due to age and cold. I thought about just replacing the hose, but I didn't really like the older compressor very much anyway. After considerable investigation, I bought this device, worrying a little about the size and weight and the need to connect it directly to the battery. However, my reservations are gone now. Once everything was hooked up carefully (since it was my first time to use an inflator trigger device, I was taking my time), it was a very fast. I increased the air pressure by two to four pounds on 8 tires so fast that I was a little disappointed the process was over. On the other hand, I have a communal parking situation and the neighbors don't like do-it-yourself vehicle repairs in the garage, so I was able to do the whole thing before anyone could drive buy and get annoyed. Observations: The 450P is a well-made attractive device in its chrome finish. The carrying bag is useful, but nothing special. It is surprisingly quiet. I have owned six small tire inflator compressors and the noise level on this one was refreshingly quiet, with much less "rattle." This is also a plus for the neighbors. The device itself is heavy--about 10 pounds. I keep it in its satchel in a plastic tub with jumper cables, gloves, first aid kit, extra fuses and miscellaneous small tools. It's not trivial to lift the device with one outstretched arm, in its carrying satchel with hose and inflator device, unless I bring the tub close. My spouse would not be able to use it easily. The automatic cutoff was a little slower than I expected, but it definitely worked, and is a very nice feature. This is also good from a neighborly point of view. The gauge goes to 160 pounds and this is not appropriate for normal passenger car tires, because it makes the divisions too small to accurately read pressures in the 30 to 40 pound range. 0-60 or 0-100 options would be a welcome upgrade on the built-in gauge. It is important to release the trigger before reading the pressure. I bought an auxiliary tire gauge, which I would have preferred not to need. I would have gladly paid extra for an optional well-calibrated gauge in the preferred range. The quick connect is heavy duty and has a strong spring that might be a problem if you have arthritis. If the quick connect is not fully engaged, the pressure gauge goes up very high when the clamping lever is engaged--a quick sign that it's not completely on the valve stem. The reinforced hose is a nice touch. The hose is long enough reach the rear tires of a Chevrolet Tahoe easily, but not quite all the way around to the farthest tire on my spouse's much smaller car. While I don't really like having to raise the hood on my car to connect the compressor to the battery terminals, the alternative is much worse. After years of using them, I have come to the conclusion that a cigarette lighter power source is really inferior. The connections turn out to be unreliable, cutting off when I am attempting to air the tire, requiring multiple trips back to the connector. Even with acceptable amperage rating for my fuses, other compressors would occasionally blow a fuse on their second startup. This always made me wonder if the connector had come loose again or if the fuse was blown or if the compressor had overheated or died. ## Frequently Bought Together - VIAIR 450P/45043 Automatic Portable Compressor, Tire Inflator Kit, Air Compressor for Truck, Jeep, SUV, and Car Tires, Portable Air Pump Kit, Car Accessories, 100% Duty Cycle, 150 PSI/1.80 CFM, Silver - ARB 10000011 Speedy Seal 2 - Universal Heavy Duty Tire Repair Kit For Car, Truck, RV, Jeep, ATV, Motorcycle, Tractor, Trailer.
