Quoted:
Standard airgun pellet... the pointy kind.

Would depend on the airgun.
A good airgun is 15-20 ft-lbs of energy per shot.
Some of the expensive SCUBA-charged air rifles are 40+ foot-lbs per shot, but many of the plastic wal-mart things are not even 5 ft-lbs.

22LR = ~120 ft-lbs. Shorts are 65, CB's are 35 or so...

There is a video on youtube of a guy shooting a motorcycle tire at contact distance with a .475 Linebaugh revolver. We're talking one of the most powerful hanguns on earth. Probably a 420 grain LFN at 1500 FPS. They shoot it, see the impact, go to look and there is no bullet hole to be seen- it ricocheted off into parts unknown.
Physics are weird. Short of a ridiculously large caliber, I wouldn't trust anything to work 100% of the time.

You will not drive on air filled rubber for more than about 1/8 of a mile when you drive
over one of these guys or it's home made cousin.

The point was to do it from a distance, while the car is stationary or parked; not getting right there up on it and it being able to move.
All of this is hypothetical, of course.

Shoot the rim not the tire.

Rifle of course.

What if the tire is rolling? At what speed? What if it's on a treadmill?

.22LR will pop a car tire. Don't ask me how I know.

a .22 lr will do it depending on the thickness of the wall of the tire.

Wouldn't a .22 pose a serious hazard should it hit the wheel and ricochet, rather than actually punching through?

Bump for the day.

Quoted:
I've seen a car tire popped with a .22 CB through the sidewall at around 20 yards, but it took around 15 minutes to deflate.

No idea how close, but in my dad's young and stupid days he popped a neighbor's tractor tires with a .22LR.

Some years ago, I has a 3/8" bolt stick in one of my tires. I noticed it and made a mental note to get it fixed ASAP, but, being a broke college student, ASAP meant 'next time I went home and borrowed money from dad'. Besides, the tire wasn't leaking air.

Fast forward a few days: I'm driving home - in my old full-sized blazer with 2.5" suspension lift and 33x12.50 tires - hardly the most stable thing ever to hit the highway - when the bolt finally came out. I don't know if I slung it out (~70 MPH) or if I wore the head off and the rest of the bolt pushed down into the tire, but either way, a large hole appeared in the tire almost instantly. That's probably as close to a sudden blowout as you're likely to experience at normal highway speeds, and, the point is, even with a large tire suddenly going flat, I was able to slow down, steer off the road, and get stopped without any real trouble.

The point, again, is that 'movie blowouts' - where you lose control of the car - are grossly exaggerated.

The bullet usually de-stabilizes some when it hits something so people further away wouldn't have a lot to worry about but up close it definitely would hurt ya.

Shotgun, all you have to do is rack it and the tire will deflate on it's own.

I think 500 S&W might work.

If you are ever out just shooting junk for the fun of it, do not shoot tires with bird shot.

But I thought birdshot was supposed to be the best home defense load.....why would it be bad on a tire?

I have shot a unpressurized tire with a .22 and had the bullet come back and hit me when I was a kid. We were shooting at a dump and it seemed like a good target. I never did that again!

I wonder if the tire being unpressurized was the cause. When inflated, the sidewall should be more rigid and thus less likely to dent and then rebound.

And with a .22, that lead slug is going to deform and spall, robbing it of much of it's energy.

We shoot .22's at the big steel gongs at the range. The ground in front of the gongs is littered with flat, nickel-sized lead. That's just the ones that fall off the gong. Many of them plaster onto the gong and adhere to it. If the steel or aluminum in the wheel is strong enough to resist puncture, it's probably strong enough to make the lead deform and splash rather than ricochet. But, if you do hit it at a shallow enough angle, all bets are off.

Don't know about a .22lr puncturing an inflated tire but a dude I graduated from high school with took a shot at a tire swing in his back yard w/ a .22 rifle. I have no idea whether the bullet struck the sidewall or the tread (or what the distance was)... but it got him on the rebound - in the lower left jaw. It didn't buff out!

I had a tire blow out doing 35mph. It dented the quarter panel of my '79 Z28 and was so damn loud people were looking out their windows.

Shoot for rim with preferrably a high powered rifle. Tires are somewhat "self sealing" whereas a hole in metal will let out a constant amount of air.

After seeing a dog bite a sidewall and cause a leak there is not much that can't put a hole in one. Have seen pictures of a womans stiletto shoe puncture a tire. The kids sandbox is a brand new tire that some dolt cut shrink wrap with a knife and cut the side of the tire, It was on the tractor a week and ruptured and the tube was sticking out.

Maybe an airplane tire could take something more then a .22 but any car tire can easily get a hole in them.
