Always go by the cars tire pressure specification not the tires max pressure on the tire. The reason for this has to do with vehicle weight. You can put the same tire on 2 different vehicles that weigh different and they will wear different. Example 35 psi on one car may make the inner tread wear out and on the other car the outer tread may wear out. Running wrong pressure also effects gas mileage. Tell your smart buddy to go to a Goodyear or Firestone and tell them they are wrong. Also an over or under-inflated tire will void the tire warranty.

He runs 40 PSI in his tires because that is the max. inflation given on the tire.
