Sorry if this is out there but I couldn't find in the "search" for this specific tire. I jumped up slightly in size to the 75 instead of stock 70 and I really like the look. Now I am wondering what the ideal PSI is since my doorjam sticker lists the PSI for the 70.
Any Pro4X owners want to chime in since that's the stock size for you?
I moved from -70 to -75, personally I prefer 37-psi... not because I changed tires, but because that's what I ran before I changed tire size. It's not a drastic change in tire size. Use the same PSI you normally do.
