Proper PSI for a 33.5 inch tire?

BlackBandit · Sep 23, 2015

The tire tech that slapped on my 33.5s this summer put 38 psi in all my tires. I would think this is way too high and I heard bigger tires use less air to roll. What do you guys put in your 33s or 33.5s. Mine are bf Goodrich t/a KO. Also what tire pressure would be best for fuel econamy balence with tire wear for the 33s?

Most run around 30 psi. That being said every rig is different in weight so your tire psi needs are different than most. Do the chalk test to find the proper psi.
