I do hear my BFG ATs at hwy speeds, but in comparison to the Interco Tires I ran previously, it is nothing to complain about. My loudest tire was the Super Swamper TSL-SX - a traction monster.

I thought they might be annoying on the highway but they run smooth and there's no noticeable road noise. I do suspect, however, that they may have lowered my fuel economy a bit.

I use a VIAIR compressor to air down and re-inflate. I bought it on Amazon for less than $200 and it will inflate my tires from 18-34 psi in about a minute. Great compressor.

I wouldn't rely on Harbor Freight, personally, unless I knew who manufactured it.

You're usually not far from a llantera in Baja though, so I find I rarely have to use my compressor.


What has happened to WideAngleWandering???

WARNING!


i just filled 2 trailer tires with my new MV 50 and on the 3rd tire the flapper broke on the piston side. the new and improved models have the flappers pressed in, unlike in my repair thread where they used a screw.

i wish i would have kept my old unit then i could just swap out the head....

Solution!


went down to the local auto parts store and paid WAY TOO MUCH vs. amazon.com but amazon couldn't ship it for 2-3 business days. i'm leaving friday morning and the thought of driving SOB without a compressor is only a little less horrific than going without surfboards!

i'll just return the broken one in a month for a full refund.

Does any remember the way we did it in the 60's and 70's... take a spark plug out, and replace it with the gizmo that uses the engine compression to operate an air pump to fill tire... was fast, but the hot spark plug removal was the only issue.

Edit... they are still available!! http://www.aerostich.com/engineair-power-pump.html

I don't drive into Baja without Toyo's. Been running them on my Dodge 3/4 ton 4X4 (worn out two of them over the years, a Chrysler Town & Country & now a Toyota Sienna. All with Toyo. Wifes Lexus has Toyo. Tough. High mileagable. But I never felt the need for off road treads, & found the standard tread of the Toyo always "got me through" down there. Check them out. You won't be sorry.

Just out of curiosity, I checked the "spark plug compressor" website. Very interesting description of how it works --

"A pump unit threads into one of the engines spark plug holes, and as the engine runs/spins, fresh, clean air is pumped to the tires. The cylinder pump pulls air from the atmosphere, ensuring no gas or oil fumes turn your tires into a Hindenburg wannabe."

Really? So how does it stop the fuel delivery system from operating? Seems to me that the injectors/carburetor won't know the difference and will still be supplying fuel/air mix to the cylinder.

Am I missing something ????? :?:

Nope, your right on target !! The injector will be injecting fuel and mix with the air and get pumped into the tire..(bad)..If you plan on being off the pavement IMO get the best pump you can find....nothing worse than getting to the last tire on your ride and the pump fails....1 low & 3 full......:lol:

Nope, clean air goes into the tire... for the few minutes you are filling the tires, unburnt fuel goes out the exhaust. The compression of the engine operates a check valve where air enters the hose to the tires.

If you want real air off road, this is the best system: http://www.kilbystore.com/

It's nice to be able to run air tools when the situation arises!

Brad Kilby is a good friend of mine and quite a few of us helped develop/field test this system.

Pull the fuel pump fuse in your vehicle. That will stop any fuel from getting into the tire. For a 91 chevy 4x4 it's under the dash driver side and it also supplies power to the auto tranny clutch.

We used the spark plug pump many years ago in our sand rails - never got any fuel into the tires.

On almost All fuel injection systems..Fuel is injected while cranking !! On a older RAIL with a carb would not be a issue..the AIR BOSS looks nice.. Or you do what I've done for a lot of guys use the A/C cpmpressor as a air pump !!:bounce:

Guys, I don't have the spark plug device anymore... but in the 60's and 70's THAT IS HOW it was done... ;)

I think we got it from Dick Cepek (do any of you kids know who HE was?) Not a tire brand then, he sold Armstrong tires... like the TRU TRAC and HI-WAY FLOATION tires. I had them both on my Baja buggy and Jeep. His stuff was BAJA-PROVEN ! :wow::yes::biggrin:
