tire pressure without beadlocks

[gordo]

Thx for the input everyone. I was at it all day with Southeast Raptor group and funny thing is my tire pressure gauge exploded as I was airing down the 1st tire LOL so I ended up running 36 all the way around as that was what my display said. It worked out fine. Next time I will be better prepared and test out a few runs with different pressure. It was mostly sand. Not too deep. Averaged about 30 mph. Went as high as 60 and got a little air too. I am hooked! I’ll try to post a few pics and video.

you can geta a really small compressor that plugs into your lighter socket

no don’t they will fry inflating 35s
you need something that goes direct to the battery and even they get too hot to touch

Why not use the 110 outlet? Take a look at watts on 12 volt vs 120

Most of the lighter socket compressors are far too weak to handle the demands of airing up larger tires. Adding a little air to small passenger car tires is just fine. Refilling one from scratch, no problem. Adding a little air to top off a Raptor tire, sure.

But if you are trying to add 5 or more psi to 4 tires, don't count on it.

Get a Viair 440p: https://www.amazon.com/dp/B000X9BXQS/?tag=fordraptorforum-20

Also get an ARB deflator: https://www.amazon.com/dp/B004LQCDOA/?tag=fordraptorforum-20

Best bang for your buck out there IMO.

Viair has no issues inflating my 37s up from 15 to 38. Takes around 9-10 minutes is my guess. For $275 it's tough to pass up, if you want to go all out, go with an ARB twin portable or a PowerTank.

I would go the PowerTank route if you live near an AirGas or somewhere with easy access to fill. I'll go that route next.

I have never blown a bead and have gone down to 10 on non beadlock rims on my Jeep. The Raptor is heavier, but I have still gone down to 12 for rock crawling and have not had any problems. On normal desert trails (rough dirt roads), I use 17 in front and 15 in back. I do have an air compressor, so I do not drive very far on paved roads without airing up. I do agree with zombiekiller that experimenting is a good thing. Just don't be too worried about going down into the teens if it suits you. I do it more for comfort than traction, unless I am in sand or rock.

If you're dropping that low on 35s, what compressor are you using to fill back up? I have a cheap one that worked fine with my 4Runner but I'm a little worried it's going to crap out on me if I try to get it to fill up all four tires on the Raptor

See the post above your post Viair 440P or 400P. Awesome units.

I use an ARB twin, no tank. I also have that in my Jeep and a single in my RZR. ARBs are expensive but work really good. I use switch 5 to control it.
