will this handle 80-85 psi truck tires and approximately how long to inflate such a tire?

Asked by: Dale
Yes, I've gone from 60 to 80 psi and that may have taken a couple of minutes. There doesn't seem to be any real problem handling 80 or 85 psi.

300P Portable Air Compressor is rated 4.9 out of 5 by 8.
Rated 5 out of 5 by from Great Product Did a test with my 265/70/17's and took them down to around 13PSI, then filled them back up to 38PSI using the 300P by Viair. Came out to be around 2 minutes per tire. Much quicker than my old compressor that plugged into the cigarette lighter. Very happy with the product. Only CON: The battery connecter cable could be about 3 to 4 feet longer. I have to clip the battery cables to my battery and then hang it just off the front of the truck just to hit the ground, then walk the air cable all the way to the back of the truck to fill the rear tires, putting tension on the unit and possibly tipping it over.

Rated 5 out of 5 by from Great Portable Compressor The compressor is compact, very portable and easy to use. It quickly and easily tops off my 80 psi truck and trailer tires. I have not needed to use it to add more than 20 psi to a tire so I don't know how long it might take to go from 0 - 80 psi but that would be a very rare occurrence anyway. The one thing to be aware of is the included air hose does not stretch out very far unless the compressor is anchored down or held - I had an old hose laying around so I threw it in the carry case and just link the two hoses together if I need to stretch it a greater distance.

Rated 4 out of 5 by from Good Step Up From Cheap Inflators Would give it 5 stars if I had owned it for a long time, as it is I have only used it a few times. I have vehicles with leaky tires that need to be topped off often. When I use the cheaper cigarette lighter plug in inflators they tend to blow fuses in the car and sometimes just burn up. This compressor running straight off the battery appears to have the muscle to get past those issues though I haven't filled any giant truck tires with it. It looks and feels well constructed, hose snaps on easily, etc. Only drawback is the pressure gage doesn't read accurately while you're pumping, you have to switch it off to check pressure and the switch is on the compressor, not at the air chuck where the gage is - just a minor complaint. For just upping your inflation muscle above a cheapo compressor it's pretty darn good.

Rated 5 out of 5 by from Best light-duty tire compressor I have ever used. Excellent product with quick tire inflation. Connecting cables to battery terminals are a bit short, making it awkward in some cases to keep the device on the ground and not partially suspended by the cables, which definitely should not happen. They should be at least 18 inches longer. But they can be worked around, and this is the best light duty compressor I have used.

Rated 5 out of 5 by from Better than expected. I purchased this for my Ford F-250 7.3 Truck. The suggested psi is 80. No issues whatsoever pumping air into the tires, which usually takes 5-10 minutes depending on how much air the tires need. I just to play around with positioni of the unit to get back to the rear tires, but no big deal. Seems like a well built unit with a nice sturdy case.
