In the process I broke off three of the screws that hold the tire onto the car? Now what do i do? Cant drive the car with only 2 screws and bolts holding the tire on? Tow it somewhere? what sort of damage has been done? why did the screw break off in the first place? Is it something I can fix myself? Please help

Yes, this happens often and for various reasons.
- Yes, it's true that overtightening the lug nuts can weaken the stud bolt and cause it to break due to the stress, but you would have to really overtighten it to cause this. Overtightening the bolt will cause the metal on the threads on both the stud and nut to have excessive wear and leave metal filings behind that will cause the nut to bind up on the stud instead of moving freely (this can also happen even if the nuts are not overtightened but put on/off frequently and/or the nut & stud threads are not cleaned off/out properly each time the nut is removed).
- Another reason they break is when the threads are damaged on the stud (either by impact by a hard object when the nut is not in place, cross-threading the nut on the stud, metal filings from stud/nut, or rust) and they become hard, or impossible to turn/remove due to the excess metal filings on the threads and the excess torque required to remove them causes the stud to twist and break. Any damage to threads will transfer damage to the other threads and cause them to sieze after awhile. Make sure the threads are clean and undamaged. If they have damage, use a tap & die set to clean and reset the threads on the studs and each of the nuts.
Normally studs are pressed into the axle plate, so to replace them you would need to press or hammer them out with a good hammer and punch and set new ones back in carefully. Usually by just pulling them in using the wheel nuts against the backing plate that the studs are mounted in (use the flat side of the nut if it has a tapered side as you don't want to damage the tapered end), do not pull the studs in with the wheel in place as that will cause some damage to both the nut and wheel from the force required. If need be, use a large washer as a spacer. Apply a light coating of oil or grease on the threads and the surface where the nut is touching.
Best of luck.

Use a big hammer and beat the broken studs out the back. Buy new studs and lug nuts. The studs push through from the back. Align the teeth on the stud with the holes in the hub, and put them in as far as you can. Then put the wheel on the car, and tighten the lug nuts on. Then loosen the lug nuts and re tighten. The lug nuts will draw the studs the rest of the way in. Be sure to check that they are all the way in before the final installation of the wheel.

Stud's usually break off from being over-tightened or cross-threaded. Or, by turning the nut the wrong direction.
Most cars, you can just use a ball-pean hammer, or b/p hammer and punch to drive the broken stud back thru from the axle or hub. In some cases, you actually have to remove the hub from the car to get the stud's out. It depends on what model you are doing this to.
You'll need to know what stud's you will need and can readily get them from most auto-parts stores or tire-shops. For really-old vehicles with left-hand treaded studs, you have to go to NAPA, CarQuest or other higher end parts store to get them.
Installation can be tricky. In some cases you can get them seat installing the stud, putting the tire on and tightening up the lug nut.
Remember, torque mags to around 100ft/lbs or steel wheels to around 75-80 ft/lbs. No more unless the rim had instructions todo so.

you will have to put new studs in. I have had this prblem before. you should be able to pound the old ones though the hub and draw the new ones in with the new lugnuts you need. when drawing in the new ones put alittle bit of grease on the threads and the seat where the lugnut tightens against.(it will make it easier) and draw the new studs into the hub. BAM. your problem will be fixed, just make sure you really tighten the new ones up checking to make sure the stud is totally seated against the back of the hub. I put a little bit of never seize on the studs this help this not to happen again later

Don't settle for less than the best relationship. If your boyfriend can't be consistent about how he treats you, ask yourself how your relationship with him will be in 2 or 5 years. Do you want to be happy? Don't set yourself up for misery. Saying he's sorry doesn't mean a thing if he doesn't change the way he treats you. No guy is perfect, but unless he proves by his actions that he can respect you all the time, get out.

Yes you can fix the problem yourself. The Stud comes out.
It comes out the back. It has to be punched out. You can buy
the studs and the nuts at any auto supply store. You should
probable buy a tire at the same time to stop your flat tire
problem.

the reason this happens is when the tire is put on the air ratchet pressure is set to high, when you try to take it off with a lug wrench you do not have the hammer effect a air ratchet has

Pound out the studs and replace them.

Depending on the car. you can buy a hub with all the studs in it and change it . may be cheaper in the long run.
As far as them breaking somebody probably cross tread ed them.
