Hey Ya'll,
I refuse to believe that a tire manufacturer would put a max inflation number on the side of a tire that was higher than it was safe to inflate it to. If it says Max 35 PSI, then that tire better be able to handle that pressure even with high heat conditions or inaccurate guages causing the tire to exceed that number. If it could not handle that then they would be facing lawsuits when the tires failed.
They would obviously design the tire to handle even more pressure than listed on the side to have a margin of safety to take into consideration heat and tire guage variables. This is why people get away with exceeding those max numbers, but exceeding those numbers brings the tire closer to the edge of it's safety margin. The more hyperinflated tires are closer to the point of failure wheather it is a safety or actual tire failure, but only the manufacturers would know how close.
If tire X fails at a certain PSI then they would want to make sure that no one inflates their tires beyond that pressure. They would do this by putting a number on the side of the tire that has a margin of safety big enough for them to feel like tire failure lawsuits would be unlikely. The tire companies would know how big this margin of safety is, but they would not necessarily want the consumer to know because they would be more interested in maximizing profits than maximizing tire wear or fuel economy.
Capriracer, would you agree to these statements? and when can we talk about truck tires?
Later,
Allan Greenblazer
