Can someone please post the stock specs for the tires? I'm working with Mickey Thompson on what they recommend for 20s and they want to know stock. Truck isn't here yet for me.

Thx

Here you go.
 
Woof - MT is coming back at 49 PSI recommended for the Baja Boss 20x12.5.

That seems insane, right?

I have those exact tires on my current 14' Sport. Yes that seems a bit high. I keep mine around what my door says around 39. No issues. Still waiting on my order. I wish I could have MT's again but i'll run with what I get again on the new RHO then switch back to MT's when those wear out....some fun driving ahead maybe i'll wear them out fast :eek:

I may try like 42 and see how that goes.

MD aired up my tires to 42 and no issues.

Yeah for some reason Mickey Thompson wants their tires (20 inch) to run at 49. I just can't see that being anything other than rock hard.

Relatively easy to trial and error though once I get the new wheels on. Probably will wait til Spring to save at least one salt season.

I would drop them down to the recommended cold 38 psi ASAP. They come overinflated from the factory, and it's possible they didn't get adjusted to the proper psi during PDI. If you keep them at 42, I assure you they will wear prematurely in the center of the tread. Just my .02
