Using a home portable compressor for tire inflation? Which one?
Just got my Porsche and the tire warning light says the left rear down -4. I'm hoping this is not a finicky system as the dealer just set to 37/44, which is on the sill plate for my 2006 911 S. Seems high and the manual shows two settings, partially loaded and fully loaded. 33/39 and 36/44. Not sure why manual doesn't match the sill plate for fully loaded.
Anyhow, I'm thinking I'll buy a home portable compressor system for convenience. Would like to know what you have and use. RJ.
Use the partially loaded numbers for better handling. It's for one or two people without luggage. The fully loaded targets are for when all seats in the car are occupied and the frunk is full.
Bruce had a good thread a while back with the same compressor question. I'm on mobile and can't find the link. Somebody will post it I'm sure.
I have a 10 gal air compressor in my garage, but dragging the rubber hose is a bit awkward. I recently picked up at Target an “Air Hawk Pro cordless tire inflator” works amazingly well. Same form factor as a power drill and has no cables
Its really quiet, which means I use it more. Its relatively light, so you can move it around if needed. It can run some power tools if needed, but obviously, since it is only 2.5 gallons it can’t do a lot in the power tool department. Overall, it’s a great compressor for small uses around the house.
See here for more.... I am very happy with my Porter Cable tank and Goodyear rubber hose setup. But.... if you want to run an air impact gun, this tank is too small.... I tried it... but that is OK with me.
Regarding loudness.... the two cheapie battery operated compressors I had were louder than the Porer Cable tank compressor.... but, there is way enough air in the tank to fill your tires so you can hit the ON button when you leave. The compressor is not loud but it is not a quiet hummer either..... we need more quiet hummers for all of us.

Went into the tire information and it did have it set for fully loaded. Changed it to partially loaded. RJ
Some confusion with partial vs full is common. Choose either partially or fully loaded pressure targets depending upon your driving habits. Then set your tire pressures to those targets AND set the TPM settings on the steering wheel lever (on board computer?) too. This lets the car know what targets your tires are supposed to be set at and will warn if the pressure is too low.
Now with that said, the TPM system can throw warnings at the wrong time. Sometimes people set their pressures to the full load but tell the TPM system they are using the lower partial load targets. This fools the TPM system into thinking the targets are lower and stops nagging about low pressures when the tires are fine. The opposite scenario causes excessive warnings - using the lower partial targets in the tires but telling the TPM system to monitor for the higher full load targets. And of course you can use whatever physical pressure targets you want, the partial/full numbers are Porsche suggestions. On the track it's common to start much lower and bleed off air as the tires heat up. It's also common to code the car with Durametric or PIWIS to disable the TPM system.
The other TPM issue I've seen is when the physical pressure in the tires match the targets on the computer but the computer thinks a previously flat tire is still flat. In those cases you need to over-inflate the previously flat tire (after repair of course) and let the computer reset. Then bleed off the air until it's at the target.

Did you have to buy any additional accessories or is it ready to go as is? RJ

I have a 10 gal Hitachi, but thing almost any make in the size/configuration that fits space available will work. Also, Harbor Freight has a nice spring loaded reel that can be mounted on the wall or ceiling. With a 50’ hose I think the cost was around $80 when I got mine.
Lately I've used a Ryobi cordless inflator for seasonal temp change pressure drops. They had this for $79 back in October, and might likely have it on sale during the Holiday season. It's good enough to handle a few pounds increase for all four tires in my Cayenne. It's not as fast as using the pancake but it's a lot more convenient.
