I don't know what your talking about...
when I inflated my tires from about 28psi to 37psi, I didn't notice ANY sort of performance difference. But I saw a HUGE MPG difference because of how much less energy it took to get my giant wall moving. If anything, inflating my tires past the sidewall max (35) actually helped my acceleration times.
Sure, my ride sucked and was bumpier than hell but I went up about 18mpg to 21mpg. that's a lot more miles per tank. And I bet that if I inflated them more I could do even better. But I'm not going crazily over the sidewall, Optimum is supposed to be 33PSI ANYWAY, so 5psi and a little sucky ride takes me a long way.
I think that your trying to make it sound like your cars tires ARE the Most dangerous threat if messed with. The Only time I have seen tire failure is from Under inflation, which overheats the tires and causes blowout and/or completely shredding the tires. Sure, it might grip better on the get go, but I see it as more of a danger when under-inflating than over-inflating.
I also don't understand, because every other day I get passed by a semi, and the only types of tires I see shredded on the side of the road are tires that have been neglected by semi drivers (having to check and inflate 18 wheels seems to me to be a hassle, especially if your in a hurry) and I know this because the treads are so huge, it can't be a car tire.
oh, and an acquaintance from my school died yesterday, he was ran over by a 10 ton truck because his power-steering went out while he was pulling into an intersection. The truck ran up onto his car and crushed the top of it, smashing the cabin. He was pronounced dead at the scene. No joke either.
That is because he neglected to fix problems from his car, and check stuff like that regularly. It was also from poor judgment, and bad driving skills.
The only way I could see tires failing to do their job, even when over-inflated is if they are old-worn out tires that need replacing, but are still on there anyway and being over-inflated. over-inflating will only take what? 1/32 of an inch of width? depending on how severe? I'm not gonna be driving any speeds which my tires would fail from over-inflating, and they're gonna last longer than if they were at 28psi. I'm still gonna over-inflate them, because I know that safety isn't a huge concern here. A huge concern would be my steering, or suspension, or airbag, or mirrors, or windshield wipers. but not how much air is in a tire.
