Why do the tires fly off of drift cars Veeky Forums?

I've been watching all these drift fail videos and there's a common theme of the tires especially the back coming off the car

What causes this? Do the axles snap? Or did the idiots just not put the tires on correctly?

The most logical conclusion is that they fucked up putting the tire on or didn't tighten the bolts enough.

>wheels must be torque'd to certain number
>weak sissy drift fag doesn't have a torque wrench, and can't even come close to the torque needed
>wheel falls off

Gee probably because cars and tires aren't designed to handle constant lateral loads. Drifters are also fucking retards running stretched tires on inappropriate sized rims at stupid pressures.

Torquing wheels is a meme. People never did that back in the day and were fine. If you've ever lifted weight in your life before you should have a good idea of how much force you're exerting. Don't go too loose or too tight and you'll be fine. I don't see race cars using torque wrenches in the pits...

Back then everyone was a man and could tighten a bolt properly

You don't see F1 or NASCAR using torque wrenches because their impact wrenches for changing tires are calibrated

It's usually cheap cast wheels they got on ebay for $75 per, instead of proper forged wheels or just plain steelies. The thin parts between the lugs break, the center part remains but the rest bounces away. Rarely it's the lugs themselves. Sometimes it's lugs being weakened by over-torquing repeatedly or using wheel spacers.

probably using stock size wheel studs. upgrade to thicker studs and the problem disappears.

Changing tires often, having wide spacer plates...
both can lead to that.

that's a full on wheel you dipshit

This. The knuckles snap or the studs


You're retarded.

you are fucking retarded. certain components need precise torque to not destroy the actual piece of equipment by over or under torque. anyone interested in performance (and safety) would use a proper torque set if they are pushing the limits of the equipment, such as under race or drift conditions.

my god... you think because you can lift a 50lb dumbell you know what 50lb of torque feels like? just, my god. There are products whose warranties are void if you don't use proper torque settings. maybe you and your piece of shit mustang are ok with guessing torque specs on high performance applications but then again you probably are a bitch.

holy shit calm down. That being said, lifting a weight doesn't equal torque, you got different lengths of torque wrenches and drives. Using a
18" long 1/2" drive torque wrench on a 10mm fastener for 20 ft-lbs isn't going to get you an accurate torque, you gotta use the right tool for the job. Back to the original topic, over torquing or under torquing will cause you to loose wheels.

sorry i got mad at u

the classic


you are a fucking moron. Go ahead, eyeball the torque spec on your wheel bearings you stupid motherfucker, see what happens. Spoilers: nothing good.

There is also this wonderful device called a torque stick which keeps your impact gun from ripping the threads off your lug studs. Most home mechanics do not have these but may own an impact wrench if they frequently change wheels. Repeated overtorquing of these fasteners will cause stud or wheel failure.

Could be anything really, the lugs may not be torqued down, the lug studs may be weak from being torqued too much, the hub may have failed structurally, the bearing may have failed catastrophically, dumb fucker running too-big spacers on too-short lug studs, cheap multipart wheel manufacture, or just neglect and corrosion.

im guessing the studs fail or the whole wheel bearing just gives up the ghost and pops out of the hub, wheel and all

There's less lateral force on a wheel that's spinning around a turn than a wheel that's gripping around a turn.

around a relatively smooth track (surface geometry, not coefficient of friction), sure. A deformation in the surface (like in the video from ) can cause huge lateral loading


IIRC that was due to incorrect (but close) thread pitch on the lug nuts

The same reason they do on this.


>I don't see race cars using torque wrenches in the pits...
Because they have torque limiting impacts you imbecile.

Fuck me you are useless.

the tyres are sliding sideways
the grip between the road and the tyre is pushing pretty much directly against the nuts and threads holding the wheel. push a wheel forward and it will roll easily but try and push a wheel perpendicular to its tread and you will be scraping it against the ground - you can feel this with your hands and its a significant force

the wheel naturally wants to stop where it is because of the friction of the tyre
the car naturally wants to keep moving in its direction because of its momentum
if the wheel bolts/nuts/threads cant meet these points something breaks and the wheel separates from the car

this is made even worse when people run grippy tyres with a lot of negative camber because the weight of the car is also being supported along the threads that are holding the wheel onto the car which just adds to the stress placed against the studs
