this should be a ad for tiremakers because they really tortured that tire and it really held up great.

[@furistasTedis]

Tire won’t explode for piercing it, well, very tiny chance. There are a lot of factors like under/ over inflated tyre working on road, air temperature, but when it goes boom, trust me, you don’t want to be anywhere near it. Short KZbin search truck tyre explosion would give you an idea :)

[@bradmullaerialphotography]

As a truck driver it’s a one in a million shot a blown tyre damages a passing vehicle. It’s the failed tyre throwing debris as it rotates that does the main damage. Just like you see here.

[@Matthew-h6e]

I agree. Most trailer tires are retreads, so I would assume that it would be the retread coming off that might do damage. I've often heard the debris on the highway referred to as 'gators', not that most people care enough to give them a name. I've had my Class 1 (Alberta semi truck license) for 22 years, for what it's worth. Afterthought: it wouldn't surprise me if retreaded tires are subject to regional laws. I wouldn't be surprised if there are many jurisdictions that don't even allow retreads to be run.

[@janjochem20]

@@Matthew-h6e in the netherlands you can only retread 1 time after that the tire must be replaced

I've witnessed an actual semi truck tire blowout on i80 somewhere around Omaha, truck was going at least 80MPH. Let's just say I was happy to be a few hundred feet behind. Don't know if it would have been enough to behead someone, but it went up in a big cloud of smoke (initially thought the truck had exploded) with big chunk of rubbers all over the place. Quite humbling.

[@bowenwalker2087]

I Drive a truck for a living, the worst place you can be is behind a truck when a tire blows, here is Aussie land people seem to think that sitting behind a truck in kangaroo country is a way to stop yourself from hitting one with your car, when in fact the truck is like a honey badger, don't give to shits when don't even slow done.. just bonk the bull bar rolls it straight under the truck, the it flies out the back.. or goes under the wheels... you get the picture

[@danholman7105]

Tridem rear inside tire, back axle, on a super b bridge blew at 100 k. Tread. Big pow and serious jerk on the rig and upon inspection the extra heavy mudflap hanger was driven into buddy tire cutting deeply. The flap no longer existed. Help 20 k away so attempt to shift hanger pipe with a 5' pinch bar and limp in just bent the bar. That is extreme energy and on a linear release only a fool could doubt it's lethality. Linear. A release when beside might injure but hardly be deadly. Upon replacing 4 tires the shop straightened the hanger bar by heating it red hot while other buddy used his longer pinch bar on the softened steel. Like I said, linear release every deadly.

[@zedpoutine]

I would've liked the drafting test to include the fuel used by the truck. Either - it would use more as the car inside the low pressure is being partially pulled (sucked in) by the truck or - use less since the low-pressure size is smaller thus having less of a drag holding back the truck or - a little bit of both cancelling each other.

[@MichaelKingsfordGray]

Conservation of energy means the prime mover's mpg would decrease. It is hauling an extra parasitic load. Physics does not lie.

[@carmatic]

Actually i think that the fuel usage of the truck will also decrease, because the car behind it is stopping the air vortices from forming

[@grejsancoprative]

Whatever the numbers would be, it would be insignificant. Remember in terms of fuel consumption to weight a truck is way more fuel efficent than a car is. My truck can haul up to about 60 tonnes legally, and it does about 3.5 liters per 10 kilometers at that weight. It isn't even in the same galaxy compared to a average car.

[@juliantavalin4842]

I love how the drafting part is basically just them telling you over and over not to do it.

The car behind the truck with 94% drag reduction makes sense.. as the truck moves through the air, there’s a literal negative pressure zone behind the truck a trailer.. it’s almost as if you’re moving 50 mph through a vacuum because of the negative pressure zone

[@LoloPeinado-v5b]

that's what they said on the show, dude.

[@svampebob007]

That makes sense Dead Zone a protected area where the oncoming smoke doesn't reach protecting any following car from drag smoke was gathering behind the truck which proves to us that there is a low pressure area what we're going to do now is take a car in the same scale as the truck attach it to a force gauge and then see what kind of effect that low pressure has on the car but just before that the team first needs a baseline so the truck is removed from the track to see what the force of the oncoming wind is like on the car alone with the smoke off it may look like nothing's happening but the wind is roaring past the car at over 50 miles per hour and Grant gets a reading okay so it looks like we got a good Baseline definitely 0.142 pounds and that is just the wind on the car alone so that's the control the question now is will this figure reduce with a semi shielding the Airstream we're now full seven car lengths away do we have any drag whatsoever we have 21 drag reduction are you serious yeah wow for Carrie that was the wow factor so how about when the car gets dangerously close first they wind the truck in to decrease the distance to five inches or ten feet If This Were full scale all right so we're at 10 feet that's a 60 reduction in drag [Music] all right we're at six feet away from the truck ridiculous I don't think I'd want to drive that close to the back of a truck let me tell you you might want to reconsider 80 reduction in drag you're not definitely Drive all right let's go to two feet what are we reading you know what's crazy we're reading 93 reduction in drag are you serious yeah it's an astounding result at two feet drag is reduced almost

for a motorcycle drafting behind a big-rig even at like 30+ meters away is easily doable and helps to eliminate a lot of turbulent air... I do it for long-hauls if I can manage it, get like 80mpg on avg.. and being a motorcycle I will out-brake it every time by a VERY long way.

[@derekrosenberg6466]

I remember as a 7 year old kid riding in the truck with my dad. It was a small Hino tip truck (6 ton I think) fully loaded with wheat. On our way to the silo's to deliver the wheat the inside tyre on the passengers side rear came apart, it didn't blow out as the tube was still inflated but the tyre came to bits. It made a really bad noise and dad said he saw small pieces of tread and wire bouncing down the road behind us like a shower of small black rocks, luckily no one was following us at the time. We had to pull over as some of the side wall wrapped around the axle and was smoking a lot. Dad cut away at it with his large pocket knife and a hacksaw blade that he found in the trucks tool kit, took about 40 minutes before we set off again. The tube stayed up all the way to the silo's and back home, round trip of about 50 km's. Not sure if the bits of tyre in this case could've killed someone as they were small pieces but it probably would have smashed a windscreen or made some dents in the grill.

When I drove the Autobahn in the 90´s I did drafting very, very often. I creeped up on a truck and saved gas every time. I just was lucky they weren´t hitting the brake suddenly. That was my only hope- at the time all drivers were using the blinkers way before braking so I usually had all the time in the world to react. But yeah, it works.

There is a tragic story of a couple driving down the highway during winter, and the truck ahead had ice buildup, the ice fell between the tyres and it launched out the back, hit the couples car, and embedded itself into the wife's head. They had newly wed just a few days ago and she survived the initial accident but the doctors said the ice ball was essentially keeping her head intact. She did not live till the next day, she actually managed to speak slightly and told her husband not to dwell on her passing, this is proof we live in hell.

[@surferdude4487]

The usual cause of tire failure is heat. This can be caused by under inflation, brakes dragging or bearing failure. Most of the time, the tire disintegrates spreading chunks of flying rubber. Other times, the tire can catch fire. It's not pretty.

About the drafiting effect behind a big truck, I remember using that, not while in a car, but when biking on frequented linear roads. For a few seconds, I could feel the air of the passing-by truck kinda "sucking me", and so, during those seconds, I could ride my bike, with no efforts whatsoever. So, I knew from the start that this myth would be confirmed :) But be careful, because the succion effect could also drive you inward the road, so hold onto your bike with a strong grip.

@@bghoody5665 You are legendary! Thanks so much!

[@AvaPxiaO]

The strips/alligators/belts we see on US hways is because DOT allows recaps on truck axles other than the two fronts. They delaminate/break and fall right off a tire, still holding its air. They will unwrap and fall behind the truck, and at best will have some speed (less than that of the truck) and fall right behind it, where if someone is tailgating will be also travelling at the same speed. So this never happens, unless a motorcyclist is tailgating a truck? So you never hear such accident because it doesn't happen. Belted/recapped tires don't explode, that is a myth, when the tire does explode from heat it doesn't shred immediately, it falls apart gradually down the road if the driver doesn't stop.

I would have been interested in seeing how that truck tyre acted under 12 tones of pressure at 100km per hour, once it had warmed up. Though more often than not a trailer tyre will throw a tread off before it will blow out.

[@Sareth94]

I think the ramping the car into the running trailer is much easier with an torque converter automatic too. It has way more 'give' to not stall out the engine or wreck the transmission. With a manual transmission, going grom 55mph to 2mph on the ramp, without taking decent run-up & clutch would probably stall the engine.

[@retrosciencefiction9839]

didn't this myth refer to 2 piece rims? "Split rims are a 2 piece construction which allowed side of the road tire changes for older vehicles. Very dangerous compared to modern designs since the rim flange can separate explosively when inflated if not seated properly."

[@pierreroberge1684]

How did you released parking brake on the semi trailer ???????

[@Hum0ng0us]

...even that junky Camaro is beautiful...

[@bkrapfl20]

Crashing into a Truck is dangerous if there is a high speed difference at the crash-point of the two vehicles. So you have to be far enough away to brake on your own, or be close enough that the truck bracking hasn't got any room to slow down siginificantly before the crash. So my tip is to add a hard bumber and just slighly hit the truck. It has both fuel savings and if the truck brakes hard it also immeadiately brakes your car. So the 2 feet test is actually probably the safest.

[@KF-zp7oe]

My thoughts exactly closer is safer providing nothing is thrown by the tires. As for the tire myth it depends on the exact blow out. If you just let the air out it is really safe, if the casing fails and 100lb piece of rubber flaps like a giant mace I have personally seen steel parts tor off the truck. Most of these retread blow outs happen on new caps on damaged casings, you can't detect all damage to a casing best to use your own not to buy from unknown source. That's why the retreads you see laying on the road all look brand new. If you run a tire low air you can seriously damage it also

Nice, but 480p sort of belong in the previous millennium.

[@dgriffen1]

I have seen a blown tire smash a car air conditioner straight out of the motor. It can do incredible damage, so the ability to kill someone is there, no doubt.

[@Netbug]

Given the weight of the car, the relatively light weight of the drive wheels, and the low torque of being in a high gear, it will work fine. The car won't suddenly accelerate, especially up a ramp. The wheels will slow down immediately. Surely not good for the transmission though.

[@xXturbo86Xx]

That wasn't the reason. I wonder why they didn't bother asking NASA about it since they did the scale model testing there anyway. The reason is that this zone is where there's a lot of turbulence that actually pushed the car back. In NASCAR when the car in the back gets very very close to the front, the turbulence that exists between them (coming mostly from the bottom) actually pushes the car in the front. And that's why drafting works even without bumpdrafting. The sweetspot is also the safest distance, provided you are paying 100% attention. Of course even though you would be saving gas money, you risk overheating your engine, and that will cost a LOT to repair.

[@kenc3288]

Unless that pickup had a locking differential, did you prevent the RH pickup wheel from rotating..?

[@thebreakofdon5188]

Good video. There's 2 problems with your tire test. The wheels of the folklore are the old 10.00x20 split rim withe the locking ring. You're definitely on the right track when you were running the truck tread through the 2 tires. For that real life scenario you should have used a recap tire. Be nice to see this again with those scenarios. 30 years on the road...just my 2 cents.

[@Hellsong89]

Those split rims when failing are powerful enough to behead just from ring alone from normal tire pressure. If it was not assembled correctly or locking ring is rusted out, that thing will come apart and if there is pressure in tire results for anyone being in general front vicinity are BAD. Another would be tire frame that has gone too many resurfacings, the frame it self failing, specially if that happens behind the outer wheel, followed by outer side wall failing.

Chapter 9 - its thesame concept of two cars going same speed so to the 2 drivers their speed relative to the other is 0 otherwise its impossible to do the 'balance a plank and people move between cars' stunt or do midair refueling; but here the car behind must be slightly over 55mph to catch up by 1-2mph. The car relative to the road is 56-57mph and once on ramp f=down to 1-2mph; they had to exceed 55 to catch up and move in unless they compensated by driving the lorry 53-54mph so thr car can catch up at 55mph and still have enough velocity to park once on. physics is counter intuitive and confusimg! A ccording to physics, you are not moving when speeding down a motorway but instead the motorway is moving according to the driver. velocity makes no sense unless compared to something relative

I've seen that sort of thing fly off trucks more than once. thankfully it ususally doesn't fly in huge chunks and doesn't go too far. I think being on the road changes directory a bit differently from driving on another set of wheels as well.

[@Chrisamic]

I really hate it when the mythbusters, my heroes, get a myth totally wrong. It is truck split rims that will kill you, when the rim separates from the wheel. Everyone knew this even back then, it was no secret. When we inflated split rim wheels after a tyre replacement, we always did it with the tyre in a steel cage because the high pressures being applied could cause the rim which weighs many kg to separate. People have been cut in three pieces by spit rims. Some years ago I heard about a fire fighter who was killed in a factory fire when he approached a forklift truck with split rims and tyres on fire. It failed and killed him instantly.

[@Hellsong89]

Worn out tire frame, fuck up in resurfacing, too little pressure causing heating from flexing combined with centrifugal forces and maybe bump in the road. All those are reasons that can cause tire failing. Seen many times side walls just disappearing and leaving the tread circle. Combine this with frozen temps so tire goes up and down on the heat circle and i'm no longer wondering why there is so many blown truck tires on side of the road...

I think what would happen is that the car would stall as the driving wheels hit the ramp (assuming the driver is using one of the top gears)

[@stunt_driver]

@@marjoh669 Yes if you were to hit the ramp without clutching in, however if you build enough momentum you can probably clutch in just before your rear wheels hit the trailer ramp and quickly switch to first/2nd gear, more difficult but not impossible I think, although I don't know how long the car can keep a higher momentum while the front wheels are on the ramp

What is a "deer slug", isn't "buckshot" mean for shooting deer? I'm a novice hunter and only have experience with waterfowl

I was sat in the passenger seat of my uncle’s car when he was overtaking a truck, the front Tyre of the truck went and my window was down, the slap that i got from the carcass left a permanent mark on my face and it was only a small piece, I got lucky 😂😂😂
