I found this load/inflation chart useful for my 2020 JLURubicon. Based on the door sticker of 3100 GVAR (front and rear) for my Jeep, the tire inflation sticker on the door of 37 PSI is too high for a load of only 1550 per tire.

This chart only goes down to 2105 lbs, so inflation of less than 35 for daily driving would likely be OK.

BFG KO2 LT285/70R17


35 psi for load of 2105 lbs per tire
40 psi for load of 2315 lbs per tire
45 psi for load of 2510 lbs per tire
50 psi for load of 2755 lbs per tire
55 psi for load of 2900 lbs per tire

What PSI do you run for highway use?

I ran the stock 285's at 35psi cold, because anything lower triggers the tpms light on the dash. 32 felt better, but that yellow light was irritating.

I'm now running 315's, but the C rated ones, at 30psi cold. Those E's are pretty stiff for a wrangler. What size wheel? If stock, you'd have to run them pretty low to pass a chalk test.

For me, on airing up, the light goes away at 35 psi, but you can then lower it down to 32 without triggering the light. The low threshold is something like 30.

Oh, I did not know that. I switched to 35's and got the tazer mini before having the chance to play with the system on factory settings. Thanks for that though! I now have more info to pass along to the next person.

Have a great day, Jerry!
