When attempting to change a tire on their BMW, some drivers might ask themselves this question. BMW lug nuts are not reverse threaded, which is the correct response to this query. The driver of a BMW must tighten the lug nuts in a clockwise manner with a torque wrench in order to change a tire. If this isn’t done, the lug nuts can come free and the driver might lose control of the vehicle. It’s critical for drivers to understand how to change a tire on a BMW appropriately because doing it wrong can be risky. Drivers should take the time to learn how to change a tire on their automobile before they need to use it because there are many internet sites that can show them how to do so.
There are a few things that drivers need to remember when changing a tire on a BMW. They must first confirm that they have the appropriate equipment for the job. This contains the socket head and lug nuts that came with the automobile, as well as the torque wrench. A 17 mm socket head is used by the majority of BMW vehicles, therefore owners should ensure they have the right equipment before beginning any repairs.
Drivers should become familiar with where the spare tire and jack are located. The jack is typically positioned close to the spare tire, which is typically found in the car’s trunk.
Drivers can start replacing a tire once they have acquired the required tools. The lug nuts on the damaged tire must first be loosened. A lug wrench or socket head can be used for this. The driver can remove and set away the lug nuts once they are free. The car must then be raised till the damaged tire is off the ground by placing the jack underneath it. The driver can swap out the old tire for the new one once the car has been elevated. After changing the tire, they must re-lower the vehicle to the ground and use a torque wrench to tighten the lug nuts.

The lugnuts on the left side of the car have a reverse thread. They tighten/loosen in a really strange manner. Lugnuts are always tight on the right and left. I don’t get it.
Actually, some vehicles and light trucks have left hand thread on the left side wheels, therefore lug nuts aren’t always left loose but tight. Though it never really made sense to me, the assumption that the nuts would be less likely to come loose if tightened in the direction of vehicle travel.
Even though I have worked on cars for years, especially European automobiles, I have never seen anything like this on a car before. I’m sure there are cars that are like this in reality. This is how every car in the game looks. Instead of doing it on purpose, it appears more like they simply duplicated one side of the automobile onto the other.
Yes, I haven’t seen that in a very long time, certainly not on the project I’m working on now. However, I figured I’d post the information because I’ve seen videos and comments about it all over the internet. I do concur with you, however I personally don’t find it bothersome when code is just copied and pasted, it seems to disturb quite a few people.
Guys, those are wheel bolts, which are often found on European vehicles like BMW, not even lug nuts. I personally know the FD3S RX7 has nuts and wheel studs.
We are aware that they are allen head bolts. They are still referred to as lugnuts. Hey you need pull the WHEEL BOLTS out? I’ve never heard that, lol.

Those must have been vintage automobiles! Since the automobiles of the 1950s, I haven’t seen any new threads.
They had a left/right side thread at the time and believed that inertia would loosen one side. That was overthinking, in my opinion; it will never happen.
Chrysler used to do this on every one of their vehicles, but I believe they stopped in the late 1960s or early 1970s. The threads on one side of the 1967 Plymouth Valiant, the everyday car of my dad, are the wrong way around.
You might not get a response because this is an old thread, and you might be restarting an old thread. Consider starting a new thread, please.

Are the locking wheel nuts on BMWs uniform?
Yes is the short response. At the very least, they are exclusive to the locking wheel nut set that your manufacturer gave you as your car was rolling off the assembly line. For instance, you wouldn’t be able to remove the wheel from your Toyota using a BMW locking wheel nut key.
Can you manually overtorque lug nuts?
You now know how to remove your lug nuts without a torque wrench and how to tighten them back up. And that getting a professional or someone with a torque wrench to look at them afterwards is still a good idea.
Can you manually overtighten your lug nuts? Indeed, you can. if more than just your car is damaged. You could tighten the nuts more than the specifications specify if you had the appropriate strength.
The inverse is also accurate. It probably goes without saying that you will never be able to tighten the lug nuts enough to keep your wheel on if you are unable to independently open a jar lid.
Additionally, utilizing your body weight as leverage with a tire iron or the natural torque you’ll discover with an extension breaker bar will work if your lug nut is tight and challenging to release.
What occurs if lug nuts are torqued too tightly?
On steel and the majority of aluminum wheels, a lug nut—also known as a wheel nut—is a nut having one rounded or tapered end. There are 4 basic varieties of lug nuts, which are used to secure a wheel to threaded wheel studs and subsequently to the vehicle axles:
- conical seat
- Cone-bulge seat
- Flanged
- Spiked Swivel
The star-shaped pattern in which lug nuts must be fitted guarantees that weight is distributed evenly over the wheel mounting surface. It is strongly advised that you use a calibrated torque wrench to tighten them; however, you may also use a socket or impact wrench for the final tightening. Manufacturers specify suggested torque values, which should always be followed during installation. After installation, you should re-torque after driving the vehicle for 50 kms. Torque parameters vary based on the vehicle and wheel type. Incorrectly torqued lug nuts may lead to:
- rotors with a warp
- lug nut seating surface damage
- wheel hub injury
A common torque standard chart is shown below. According to lug nut specifications, threads must be clear of debris such as dirt and grit. Since the seat of the hardware is the primary point of friction where torque is measured, it is forbidden to add lubricant there. It’s crucial to keep in mind that while tight is desirable, excessive tightness is not. It is crucial to be aware of the manufacturer’s recommendations because excessive tightening might strain the stud and lead to failure surrounding the rotor. Using a torque wrench to tighten each lug nut to the recommended torque values is the appropriate method to do it. There is a danger that the lugs will break under normal circumstances and your wheels will pass you in traffic, which is rare but does raise a safety problem when you over-torque the lug nut and render it no longer qualified for the weight rating.
There are several various kinds of torque wrenches available, with the click type being the most popular. To use one, simply turn the wrench handle until it reaches the desired torque level, then begin tightening the nuts. You will hear a clicking sound around the wrench’s head when the specified torque is met. There is also a dial-style torque wrench; it has a tiny meter on the handle, and as you exert effort, you can see the torque increasing. You can read the precise torque with some dial torque wrenches that have an electronic meter on the handle. Although the typical lug nut torque for steel wheels is around 80 ft/lb and for aluminum wheels is around 100 ft/lb, you should still check the manufacturer’s recommendations.
Can WD-40 be used on lug nuts?
It is frustrating to be unable to remove a lug nut because of rust or someone overtightening it, whether it occurs in your driveway or by the side of the road. Please continue reading before attempting to spray something lubricant-like like WD-40 on to try and loosen things up.
If you’re trying to remove lug nuts or clean out rust, you shouldn’t use WD-40 on them. You run the risk of overtorquing the threads if you prepare them with oil, grease, or an anti-seize agent before tightening your wheels.
WD-40 usually serves as more of a temporary cure. There are numerous safer options, which I’ll discuss in a moment, that can solve your problem if your lug nuts are sticking.
While WD-40 could come in handy in a pinch, it can seriously damage your lug nuts and studs, which could put you in danger while driving.
How do you tell whether a nut is threaded backwards?
Basic Bolts The majority of bolts have a right-handed thread and turn clockwise as they are tightened. Such a bolt appears to have threads that slant upward and to the right when you look at them. When tightened, reverse-thread bolts have a left-handed thread and rotate counterclockwise.
Should lug nuts be loosened before jacking up the car?
- security first. Maintain a safe distance from oncoming traffic, put your car in park, engage the parking brake, and turn on your warning lights. It is preferable to ask for roadside help if you are unsure that you can avoid danger.
- Consult the owner’s manual. It should have directions for changing tires, including where the jacking point is.
- Bring out your spares and tools. Typically, they are kept in a compartment in the trunk. The jack should provide usage instructions as well.
- Make sure the jack is set up correctly. Ensure it is positioned correctly in the vehicle’s jacking point and is facing the right direction.
- Before jacking, loosen lug nuts by roughly a quarter turn.
- The car should be jacked up high enough so that the tire is off the ground.
- The lug nuts should be taken off and placed so they won’t roll away.
- Pull the flat tire off and place it behind the jack underneath your car, or if it’s too broad, try another position under the car. This is crucial in the event that the car slips off the jack.
- Make sure the valve stem is facing you as you install the spare.
- Hand-tighten the lug nuts while reinstalling them.
- Once the tire is in touch with the ground and partially loaded, lower the jack.
- To ensure that the wheel is properly installed, tighten the lug nuts in a star pattern rather than a circle pattern. This ensures that the wheel is not out of alignment and won’t pop back into place while you are driving, perhaps loosening other bolts and causing wobbling or even worse—the nuts breaking and the wheel coming off.
- The car should now be lowered all the way. You’re prepared to make a cautious trip to the nearest tire shop to get your regular tire changed or repaired.
Spares should only be driven for brief distances and at low speeds. Your spare tire’s speed rating can be lower than that of your primary tires. Have a tire specialist inspect your spare at the shop so that it is in working order for the next time you need it.
