If anyone has recommendations on a good 12v air compressor I would appreciate it. I need to do big tires and higher pressures, 85psi or more. I have a decent compressor now but it is so slow it's killing me. This is what I have I am willing to pay good money for a great, compact 12v compressor if anyone has any suggestions. Thanks

I have been using the Harbor Freight 12v 100psi one for a little over a year, it gets borrowed every weekend we ride and has been abused on the trails. My buddy has a high dollar one i forget the name and mine is a whole lot faster than his.. its been a beast... all metal and good fittings. $35 without coupon. https://www.harborfreight.com/12v-100-psi-high-volume-air-compressor-69284.html if this one peters out i will probably go with this one next. https://www.amazon.com/gp/product/B000BM8RT8/ref=s9_dcacsd_dcoop_bw_c_x_1_w

Hate to say it, but if your compressor is working properly, it appears like a very good one for being a 12 volt unit. Big tires 85 PSI plus? For a semi, I'd have an air line with a glad hand coupler to plug in the semi to air the tires.

Not for semi so I have no available air. I have some trailer tires that need 110 and another that needs 80. My truck is 75 when I tow. Just found this holy cow, that price

A 40$ 55$ viair is about 67% faster. Hf = .88CFM viair 88p 1.47cfm if your budget is higher 3.71 CFM Output https://www.amazon.com/Compressor-Portab...+air+compressor for $180 or this slime model which is 1.9cfm https://www.amazon.com/Slime-40026-Heavy...&dpSrc=srch not sure about the durability on that one but people seem to like it. FWIW I have the viair 87P and its plenty for me. 1.26CFM rated. IIRC I paid around $45 Its light years faster than some but to pump up big truck tires 40psi, I would probably want something faster.

You're only going to get so much through the lighter socket-- anything serious will be hardwired (with quick connect) or at a minimum use alligator clips. The old jeep guys used to use a belt-driven compressor running off the engine.

Not looking for one that goes in the lighter. My current one hooks to the battery. It works fine but it is slow. Maybe I'll get the arb and some airtools:)

I use one of these: https://www.harborfreight.com/12volt-150-psi-compact-air-compressor-69285.html I used a 7 port manifold to make a device with 4 air lines, a gauge and a ball valve so I can deflate / inflate all 4 tires on the Jeep at once. This compressor works great! I've inflated my 4 33'' tires, and another set of 32'' tires without it overheating. Was really surprised at how well it works. I also use it to inflate the 4 truck tires on my truck after putting it in and out of my garage.

My dad has a Viair and he swears by it. Not sure which one he has but knowing him, it's one of the bigger ones.

I use a small 120v hot dog compressor on an inverter. It takes more space, but unless you want to spring for something like that ARB that is probably the only way you are going to upgrade from what you have.

This is a great idea. I already have a hot dog compressor at the house. A good inverter is way cheaper than the arb and it might come in handy for other things. Thanks for the idea.
