Will my tires really explode?

I don't know about the exploding of your tires at 80 psi, but you will not get the best mileage from them running at the max. pressure as if you were hauling the max. weight for your truck. To get the right pressure for your weight you must weight the front and rear axles and use the load tables. Check out these load tables here:

You will have a muchbetter ride also with the tires at theproper pressure for you weight.Good luck, MR

Whether it "explodes" or rapidly looses air (blowout) you still have a catastrophic situation, so the difference between the two is irrelevant. B

Actually, my real question should be restated. If the tire is rated for 80 PSI (I've always been told to check it cold), then the tire should be designed to handle the increased presure when it heats up, even if ambient is 120+ outside. I understand that the guy used the term explode to scare my wife, and that a blowout is probably what he meant, but the question still stands. Am I setting myself up for a "blowout" by using the maximum rated presure, and coming nowhere near the load rating?

they are stock size) (usually it shows there or the manual) The psi on the tire is the MAX and is most likely too much air. Check them cold. They wont explode if you dont go over max but they will wear out in the center and ride rough with too much air for the weight of the truck . So, in a nut shell, he doesn't know what he is talking about.

p.s I wouldnt check them cold in the north pole, then drive it down to vegas and expect them to be right. Its a relative thing, you know? Cold right now in vegas is about 100, when they say check them cold it means dont check them after driving on them. If you put them on ice for a while, then fill them to 80, then drive them on the highway for a while they will have way too much air...does that make since. OK I'll shut up now. :)

That makes sense, I understand that cold means sitting in the ambient environment, warm is up to operating temp. I guess 65 psi is about right then.

Thanks for your help everyone.

Ok if you put it like that i guess that qualifies as an explosion :) I've seen it happen on big trucks from time to time, must be a real scare when you're driving that thing and it happens if you ask me.

1.. To release mechanical, chemical, or nuclear energy by the sudden production of gases in a confined space: The bomb exploded. 2.. To burst violently as a result of internal pressure. 3.. To shatter with a loud noise: The vase exploded into tiny pieces when it hit the floor. 4.. To make an emotional outburst: My neighbor exploded in rage at the trespassers. 5.. To increase suddenly, sharply, and without control: The population level in this area has exploded during the past 12 years. 6..

Again from Webster's.

I wasn't driving, but I was in the back of a school bus when a rear tire let go.... good god that was loud. the ass end of the bus jumps about 6" into the air too. the driver didn't seem to have too much trouble with it.

No....and depending on what your vehicle is and what tires you have....80psi is the cold setting. I believe I've seen that spec on the doors of 1 ton G-vans. And that is the max pressure rating for the tires.

US-14 atop the Big Horns, between Burgess Junction and Shell Canyon, heading for Yellowstone

ME, 5'-6" at 12 years old, stretched out crossways behind the rear seat with my head on one wheel well and my feet on the other

tire blew out right under my head

after Mom got it stopped, we started changing it

a cowboy (real, live cowboy) came riding up and told us to pull it back up onto the pavement and change it there, because 'all you'll do is sink the jack and not lift the car'......he rode back up the road about 1/4 mile and watched for cars while Dad changed the tire and I changed my BVD's

Hello all...

Been reading along the thread here and I guess I just do not understand as usual.

For all my driving life, I've inflated my tires to around 30~35 pounds of pressure. Never had a problem doing so, and the tires certainly don't look flat.

So...what's the story here?

What are you referring to when you say you don't understand?

We're talking about a truck that weighs 6000 lbs with nothing in it. That's

1500 lbs per tire (about the same front to back). 30-35 psi is typical for passenger cars, and I believe close to max on p-rated tires. With as little as 50 psi in my tires, they appear slightly flat. 65 Looks fine, I've been putting 80 (max tire rating) figuring I'd get the best gas milege that way. The consensus seems to be that if I'm not hauling, then best mpg is found somwhere in the middle.

Many heavy duty truck tires have 60 to 80 psi operating ranges. You never see it in the P's (passenger tires), it's in the LT and ST ranges. The stock rear tires on the Dodge 2500 with the Cummins are up to 80 PSI fully loaded, and about 40 psi unloaded. You start seeing these pressures on 2500's and up.

max pressure is not appropriate for most vehicles. they are only appropriate when you have an exceptionally heavy vehicle (xcab/crew cab diesel for instance) and on such vehicles the placard will reflect this. If I were you, I'd have left out the fact that you were a tire monkey, not exactly top of the totem pole. and no, I don't own any fords.... period.
