I still go with Tire Shop guy. They hire or have risk managers and lawyers to review procedures, follow standards and whatever else it takes to not kill their customers or damage their cars.
If he wants to verify, I guess a good place to start would be “ask him why the difference”. Young and inexperienced and doing exactly what the boss trained them to do.
Honda is not going to replace the tire if it comes to that. 99+ % of tires
on the road are at a pressure where Tire Shop guy put them and owners keep it
there because Tire Shop guy told them to do that. Guess we have a national safety crisis on our hands. For every bad news story about about Tire Shop guy, I’ll match you one on one for any trade or profession. Better verify your dentist, plumber, surgeon, electrician…
