I think that what tires bear on their sidewalls is the maximum pressure you should not exceed when inflating the tire and not necessarily the recommended pressure for driving. The recommended tire pressure for your vehicle will be written in your car's manual and the sticker by the door frame. Eg for a 2003 accord LX its 30psi front and 29 psi back.

Martini101: Op. Nice topic. This is still on the Ist page since January! If it were "Share Your Sexiest, Craziest, Funniest Or Unforgettable Experience", the thing go reach 20pages within d twinkle of an eye!! Which way guys?

Wallie:

An overinflated tire won't cause your tire to explode! Overinflation of tires will generally lead to more wear and rough handling of your car. It can also reduce the effectiveness of your brakes because you will have less contact patch (the surface of the tire becomes more rounded instead of being squared).

The rough handling occurs due to the sidewalls of the tire becoming unyielding (no deflection). You will feel every single bump on the road.

In reality, you have to adjust your tire pressure based on the load your car is carrying, which is why your car manual should give you a separate tire pressure for “max load.”

Underinflation is what causes tires to explode due to the heat being generated by the tire (too much friction).

oga we know say you sabi book, after all, you dey look women bobi for lecture hall, abeg borrow your son's physics textbook SS1 and read about "hooke's law" then come back and laugh at the bold part of your comment

Wallie:


I guess you want to hold what I said in absolute terms and out of context. Take a look at post #27 where I clarified what you had in quotes. And while you're at it, take a look at post #31 where I showed what will happen from overinflation. If your car manual recommends 35psi and your tires are inflated to 40 psi, is that overinflation?

My response that you quoted was in reference to the OP’s claim that the tire could have exploded because it was inflated to 60 psi instead of 40psi as claimed by the vulcanizer. I responded saying that the tire couldn’t have exploded from being overinflated (to 60 psi). Anecdotally, the post by @amdman supports my claim because his tire was inflated to 70 psi and he traveled that way from Benin to Lagos.

Einstein, your arguments about elasticity limits is like someone trying to make a point about something that will happen eventually even if it takes a million years. Of course a tire will explode if you keep pumping air in it past its elastic limit but will that occur when you add an extra 20 psi? No. How about an extra 40 psi? Probably not but if you keep adding air, it will explode sooner or later!

Oh, and you are right about me looking at bobi in class. I saw absolutely nothing wrong in playing with bobi while I aced my courses! I was certainly good at it because I made out like a bandit by any measure you choose! My apologies if you didn’t get the girls and the grades.
