My dad's older tires on his car had a max PSI rating of 35 while the newer pair that were added on have a max of 44psi.. The OEM tires for the car were Michelin Energy MXV4, max 35psi while the replacement were too Michelin Energy MXV4 but a max of 44psi...😱 I have never seen a (automobile) tire that has max psi at only 35. Can you post model (of the tire) and size? I would like to look into this.
