Tire Sizing?

[B22-2023]

Don’t rely on printed data for PSI. Look up your tire weight rating divide bronco weight by 4 and adjust PSI down accordingly.

Good system. I wound up with the earlier F rated KO3s; going by that useful formula (using my actual vehicle weight as-modded / 4 vs. sidewall max weight and 80 psi ), it crunched out 35 psi. If I had the stock WT weight though, it would come out to 31 psi. It’s nice confirmation of where the right starting point on psi is.

I ran 37’s on my JKU. Sidewalls probably said 65psi. I’d run them at 30psi around town, up the 35-37psi for road trips down to 10psi on and around the trail.

That’s more or less my range of operations too Plus or minus a few psi.
