Just upsized to 31s & wondering the ideal on-road PSI on 15x8 wheels. Comfort is my goal, but don't want to affect the handling around bends too much. Bed is empty. Thanks

 

32-35 psi

 

i've been running 24 psi front 30 psi rear for years now with the 31x10.5s on my 4runners. with your empty bed, you could get away with about 26 to 28 psi rear.

 

I usually running about 30. What tires did you get?

 

Goodyear Duratracs on my recoated stock alloys. Looks great & nice not to be over 3000 rpms anymore cruising along on the highway

 

32 front, 34 rear, 34 spare.
Give me great ride, but makes for a good solid patch of tread on the ground. Great grip in bad weather. No snow yet, but it's a-comin'!

Have fun.

30psi measured “cold” all around with my wild peaks. When the snow starts flying and it gets super cold I’ll drop to around 26 especially if I’m going to be driving up in the mountains.

 

I’m usually running 32 on all 4 of my BFG km3’s, although it still rides like a truck no matter what I might try dropping pressure to see if it improves packed snow handling….I don’t know if it will make a diff though.
