The type of AWD on the Passport is not as critical to equal front and rear wheel speed as much as some other more traditional AWD setup such as the full time AWD system on a Subaru WRX.Do you guys know if one tire is bad would all 4 need to be replaces as it’s an AWD?
On the Passport the rear axle is overdriven when engaged and disengaged as speed goes up so it doesn't matter as much. Just replace a pair if that's what you want.
Rotating tires more often will help with even wear.
