I run 40-42 PSI on the street. Anything over that and the Toyos start to crown.

Thanks Sewie.

I'm thinking I'll run 12 this weekend. If that works ok, I might try 10.

I won't know if it works until I try.

That is unless someone already knows better and speaks up.

I personally wouldn't recommend anything lower than 15 for rocks. For snow or sand maybe. Keep in mind, when going over rocks, not only can you pop a bead, but you can seriously bruise a tire making it useless.

You can do anything you like, but I would advise against it.

I'd run no lower than 15# on rock, I run 12# on sand but the isn't much to damage a tire on in the dunes...

Have fun this weekend you lucky dog....

The problem with 15 is that there is enough pressure within the tire, that it still doesn't "conform" to the rock much at all.

I realize that even at 10, it isn't gonna "conform" around rocks like a bead locked wheel at 6 (or lower).

I'm looking for a balance here that I can live with. Bruised tires are a real possibility. So are broken parts. I think running less air may also add additional stress to the already weak front axle. The only plan I have to counter this, is limiting wheel spin and hop, (trying the old BTM) and driving it slow. (Good spotting will help, I'll have Neo watching them for me)

I'm gonna give the lower pressures a shot. See if it makes a difference. It might not be worth the gamble, we'll have to see. The H3 is a good rig, it isn't gonna be made into a great rock rig, by just lowering the tire pressure. Just looking for the right balance here, if it turns out to be safe, might make it worth it. I'm glad Toyo strengthened the sidewalls on these.

Thanks for the advice, I appreciate it.

I usually just let all the air out, it gives you the most surface area.

Shut it fagger!

that .02 worth 0 on this.
