We have gone from centrifugal force to centripetal force to rubber dust on the road to squirrels to chickens with rubber necks to armadillos and o'possums and last but not least rubber nails to solve the problem. I think I have the answer. Instead of steel belted radials solid steel radials should be made. That way nobody gets a flat. No squirrels, chickens, armadillos or o'possums would get hurt and we wouldn't need rubber nails. | ||

Actually what needs to be done to solve the problem is to start making rubber nails. | ||

I thought that most people were "too chicken" to take college physics. And, now I finally understand why I keep seeing those re-tread truck tire scraps on the side of the road. Poor things tried to cross ,,,, ,,,, never had a chance. (sniff) | ||

Ed, Then those would be called "rubber road kills?" | ||

I believe the Armadillos and O'Possums eat the stuff and it kills them. You see them dead on the side of the roads all the time. Something must be doing it.  | ||

Mike that's true. The other day I was driving down the road and saw a chicken "rubber neckin." | ||

Why does a chicken cross the road? No, not to get to the other side; to eat the rubber on the road. Where do you think those rubber chickens come from? | ||

According to Websters Dictionary 2002 edition. Centripetal, Tending "toward" the center. The key word here is "toward" not "away" from the center. | ||

Semantics.....I think it is an age thing that depends on when one took physics. The term appears in Halliday and Resnick, centrifugal force being the opposite of centripetal. I think Resnick was a professor at RPI and Halliday was at Pitt. | ||

Yes ,,,, Centrifugal Force does not exhist. (Centrifugal = Center fleeing) Centripital Force and Centrifugal Acceleration Exhist. (Any Acceleration will give the illusion of a Force. Remember "F=MA") | ||

Besides eating rubber, I think squirrels also set the nails on end to puncture tires. Smart critters, those squirrels! | ||

Physicists don't like the term centrifugal force. And, yes, there is no such thing as 'centrifigal' force. Or is this a new term describing some attribute about terrific gals? | ||

Now, let me get this straight. The head of the nail gets caught in the tread. It throws the nail for a double loop where it lands immediately in front of the rear tire - flat head down. The rear tire runs over the point. The rubber abraded from the tire ends up on the road. The squirrels eat the rubber. The bacteria eat the squirrels. And I must have Michelins on my car. Now that's a syllogism. I think you've hit the nail on the head. Thanks guys. Don't know what I would do without you. Jim S. | ||

i used to get flats on my motorcyle then i put a mudflap on the fender in front of the rear tyre about dragging the ground. voila, no more flats. could it have been a coincidence? as to where the rubber goes. rain washes it away. or does it? do monkeys enter into the equation. you can't trust them monkeys. | ||

I bet squirrels eat it, you see a lot of squirrels near roads, I bet they come there for the rubber meals. | ||

The rubber is eaten by bacteria that live at the sides of all roads. | ||

Who cares about nails in tires. Think about this question: As a tire wears down through the tread during its lifetime, WHERE DOES THE RUBBER GO? With MILLIONS of tires wearing down every day of the year, the roadsides should be knee deep in rubberized dust, especially after nearly 100 years of automotive travel utilizing rubber tires. But where is the rubber??? Where does it go? Every interstate highway should have piles of black, rubbery dust piled up like black snowdrifts alongside the pavement. But where's all that rubber? | ||

Since I see a lot of nails in customers tires and the vast majority are in the rear tires, it leaves me to believe that the front tire flips the nail up and the rear tire catches it as it is spinning or tumbling. | ||

There is no such thing as centrifigal force though. Ha, I haven't gotten to physics yet, that is next year. Sorry to be of no help, in ap environmental science now (talk about a waste of time, just being fed propaganda ). | ||

Lawrence, Sounds like a possible to me. | ||
| Lawrence Coppari (Lawrence)

OK, let's see if I've got this. The head gets caught in the groove. As the tire rotates, centrifugal force causes the nail to stick out radially - just being held by its head caught between tread grooves. As the tire rotates, the nail goes around with it's point striking the pavement just ahead of the instantaneous center. This causes a rotation of the nail pulling it from the groove but winding up with its pointed end towards the tire. The weight of the car shoves the nail in. | ||

Gentlemen, The answer is obvious, just "hidden". The nail is already moulded into the tire. Once, the tread get worn down enough, the head of the nail merely touches the pavement...and the tire goes flat. David | ||

Maybe the guys name who puts the nail under the tire is "Murphy." | ||

I think Ross hits it pretty close. Most of the heads on nails that I have gotten in my tires had a larger head on them. Like a roofing nail. The head gets stuck in the tread and when it goes around it flips when it hits the pavement sending it against the flat surface of the tire and puncturing it. Then there are nails that are bent which make more sense to puncture. Last but not least as Ross says, there is some assh*le who props it under the tire. | ||

assuming the nail has a wide enough head on it, the tire could catch it on a groove, flip it up momentarily, and the next groove catches the sharp end and takes the puncture. does fall in that magoo category though. i have had about 4 punctures in the last year on the merc, and i would say everyone of them has been vandalism. one was a 2 inch bolt, no way that causes a puncture unless somebody props it up under the tire by hand. | ||

A rear tire might be more susceptible than a front. Front goes over standing it on end momentarily. Rear goes over standing nail. Or another car kicks it up. Or maliciousness. I go for years not getting flats. Have gotten two in past two months. One was a flimsy piece of wire... | ||

James, I have thought about this on a couple of occasions when I have been unfortunate for it to happen. I have to say didn't spend too long thinking about it though so no answer! (I suspect in some cases it is malicious) | ||

For those who have enjoyed the penny nail in your tire, I ask anyone to explain how it got there (discarding vandalism). Presumably the nail was lying flat on the asphalt. How does a rolling tire cause a nail to stand up and puncture the tire? I have tried to pencil this out, but simply cannot picture the mechanical action that would lead to this. It is a little easier to explain if the nail is standing pointed end up, but what is the probability of this? Any thoughts? Jim S. |
