Hi guys, i have a 2013 FF and it’s been modified to P-Zero Front 255/30/21 Back 335/25/22 I’ve been looking all over google and still not able to find the proper tire pressure for it, I’ve asked one of the wheel shop and they suggested to use 32 & 34psi respectively which I’m doubt about it. Do you all experts know what should be the right PSI for it? Thank you so much !!! Appreciate!!!
