What is your question?
My vehicle has 63000Km and recently making noise when getting over 90km/hr. I took it to the garage and was told that noise was coming from differential due to the fact that I have different tires made front ( Westlake) and Rear ( Michelin) and was advise to change all 4 tires ASAP before damaging Differential! I am a little surprised that tire of identical specs (255/55 R19) can make have differential making noise and damage it! Your Advice?

MUCH longer technical/engineering explanation to it , but ,yes MATCHING brand and size (and age/tread depth) are all critical with these. HELL ,even lowly Hondas are getting like that! Indirect TPMS and VSC/AWD all depend on very specific inputs. ANY variance causes problems.
Thanks a Lot. I finally got the answer for noise #1: my left rear tire had a bump! Changed the 4 tires and noise #1 disappeared... Now I have a new Noise #2: When relieving foot from gas pedal, hence having Motor brake effect, I have a noise like a roller bearing... or for sure rotating noise! Porshe garage, again, concluded that because I had used (For 5000Kms) different tires front and rear differentials were overloaded and now are damaged hence need to be changed!!! that sounds weared to me... any comment?
