“- With new cars, during transportation and storage, the tires are “super-inflated” way pass the max pressure on the sidewall to prevent the tire rubber from taking a set (permanent deformation) from sitting around in the same position for a long time.”
….no load…no heat build up and no impacts. In fact those very tires are only expected to last at best 30K miles. Ask your dealer why there is no warranty (without purchase) of tires on new vehicles. They are not designed to last, they are only designed to snag you as a customer for the comfort and quiet that you get initially and with a safe performance. However not on a mileage aspect. However a car tire is a poor example in relation to motorcycle tires as the demands and structure and compounds are very different.
“- I disagree that a tire would pop when impacted at rated max load pressure; that’s a law suit for the tire mfr. ” …… counter point… the reason for stamping that their is to CTOA! At any given time a point of failure happens and they can find a way to prove you’ve exceeded their recommended pressures…. end game.
I can go on all day about tires as that is my job and business. However like most things in life it is highly debated and beat into the ground. I work in the industry and see the results from real life and not media coverage or lab tests. My only recommendation is to follow your MoM and use common sense when choosing both your tire (make/tread purpose/speed rating/load rating etc. ) and your air pressures. If you decide to deviate from those (as I myself have) make sure you dig into real life, real practice examples to help you decide.
