Loading tires
 

I've read a lot, both here and elsewhere, about loading tires. My 23x8.50x12 ag tires just arrived. I'm pretty sure I'll be using windshield washer fluid. I've read that it should take around 7 gallons per tire. But I never read about adding air or how much. Is there a preferred psi to put into a loaded tire of this size?

I have always heard to put the valve stem at 12:00. Then fill the tube-tire till it runs out the stem. Then put the valve back in and fill with air to recomended pressure on sidewall.

Use tubes. After you get the fluid in, just run normal air pressure.

Oh, and I'd be really surprised if you got more than 6 gallons in there. My 8.50s are about 90% full and there's only 6 gallons in each. Still helps a ton though.

As Joe said, run them at the pressure rating on the sidewall. But be careful, the PSI will get there really fast since you have very little air volume now that most if it is liquid. You can hit dangerous pressures within seconds if your compressor regulator is at 120. Bump them up slowly...

Be safe,

Thanks to all. Should be getting the ags mounted Monday.

Here's a chart that was posted in an earlier thread:

Looks like 6 gal. is the number.

Great chart. Thanks! I'll share this with some others I know.

Matt I'm just curious about the tubes. I know you always say to run them in fluid filled tires, but I would think that if you punctured the tire, then you are going to puncture the tube as well and then what's to keep the fluid from leaking out. I can fully understand running tubes to keep the fluid from eating the rims, but I can't see how they help prevent the fluid from spilling out.

I have knocked a tire off of a rim before...pictures are floating around in here somewhere. I'm personally not too worried about punctures, as I don't have sharp objects laying around in my driveway and yard. Unless you've got a freshly-painted wheel and new tire (doesn't happen with my stuff...lol), odds are there'll be some bead seating issues. I'm not sure if the air leaked out of the tire that I knocked off, but for whatever reason, it came off the rim, made a gigantic mess, and caused me to have to change a tire 1/3 mile away from home standing in a pile of windshield washer fluid slush.

If you dont have a tube ,what is going to keep the calcium ( fluid ) from coming out of the hole it ate in your rim.
