How do I tell what size lug nuts I need for my rims?

So I was looking for rims for my car and found ones that I liked. My rims have a 4 bolt pattern and these other rims have an 8 bolt pattern. I was wondering what the lug nut size for my rims are? The person I might by the rims from said that the lug nut size are either 4×100 or 8×100. I don't know what that means so that's why I'm asking.

My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
The lug nut bolt pattern on your vehicle is 4 x 114.3. In practical terms, that means that an imaginary circle drawn through the four "bolt holes" will have a diameter of 114.3 millimeters. Of course, a bolt pattern designated "4 x 100" (100 millimeter diameter) will not work on your car because none of the bolt holes will line up.

Please note that certain wheels, even with the "same" bolt hole pattern as your original wheels, will not work properly or safely on your car due to differences in another critical wheel dimension, which is offset. Your OEM factory wheels have high positive offset and ideally any substitute wheel you are thinking of should have the identical amount of offset.

There are quite a few (dimensional) variables to consider when replacing wheels. Consequently, it is optimal to replace the wheels on your car with exact factory duplicates to avoid problems with handling and steering, interference (and consequent damage to the wheel wells) and premature wear-out of your car’s suspension. YourMechanic can help you with wise wheel and tire wheel selection, installation, and regular maintenance such as a tire rotation which is really critical because regular rotation, every 6,000 miles, will greatly extend the service life of your tires.

You can get the lug nut`s thread size by measuring the diameter of the stud it matches. Since these measurements tend to be of small circular surfaces and need to be precise, dial or digital calipers are the best tools for the job. Your vehicle may use SAE or metric: Common SAE sizes are 7/16, 1/2, 9/16 and 5/8.

That`s the diameter of the circle formed by the centers of the wheel lugs. It can appear in either inches or millimeters, so be sure you know which one you`re looking at. Bolt patterns in 4- 6- and 8-lug can be measured by going from the center of a stud to the center of the stud directly across from it.

The short answer is no. A common mistake a car owner can make is to assume all lug nuts are the same. As with any other type of fastener, lug nuts (or lug bolts) have some variation which are often preferred by one manufacturer or another. Thus, the vehicle you own plays a role in which lug nuts you have installed.
Finding the proper torque for lug nuts and lug bolts is the first step and can usually be found in the vehicles owner`s manual. Utilizing a torque wrench is a must so you can be sure you`re applying the correct torque for wheel nuts and bolts.
you can replace lug nuts while the car is on the ground if you do it by only doing one lug nut at a time. You take the lug nut off, put the new lug nut on and tighten it to the correct torque setting. then you do the same with the next lug nut.

How do I tell what size lug nuts I need for my rims?

When I try to take my lug nuts off my aftermarket rims, i end up scraping the rims,what size lug do i need so i wont do this again
ANSWER : There are many possible sizes of sockets depending on the rim design and types of lug nuts used. Most aftermarket rims will use the same size lug nuts as original but require a thin wall type socket. Take the vehicle to a custom wheel tire shop and have them check and supply the correct socket for your cars lugs. As far as the tires rubbing the inner fender you would need to have the vehicle checked to see if it needs special spacers or the tires are too wide for the vehicle. Anytime aftermarket wheels and tires are used that do not match the original sizes, you may need vehicle modifications.

I bought two new tires and rims to put on my car and I want to know if I can make them fit.
ANSWER : Hi there. Anytime you purchase new tires and wheels that are not OEM options (which this 225/45zr17 is not), you risk creating multiple issues that will impact the vehicles performance such as ABS operation, speedometer, cruise control, and braking.

The standard rule used to be, for every inch in wheel size, you need to decrease aspect ratio (the 55 number) by one (making it a 50-series tire). Width would also increase by one size (to 215 from 205). By having a wider tire on there than is recommended, you also risk having turning radius issues and braking suspension components.

Due to these facts, I wouldn’t recommend putting those wheel and tires on your vehicle. If you were to install them, you’d need to purchase new lug nuts that are snug for that individual bolt pattern. Since we can’t see them; it’s impossible to tell you for certain if the ones you have will work.

If you’d like to know for sure, consider having one of our mobile technicians come to your home to inspect your car and suggest what to do from there.

on after market rims how can you determine which size lug nuts to get for it wont be undersized
ANSWER : For your vehicle, you will need lugs nuts designated "M12-1.50". That means the lug nut is intended to thread onto a 12 mm diameter wheel stud with a thread pitch of 1.5 mm. However, you need to select a style of nut that is intended for the type of mounting seat that exists on the aftermarket wheel. There are different types of seats and selecting the right one is critical so that the nut actually stays tight. As well, you have to be sure that the thread engagement (depth that the lug nut engages on the wheel stud) is the same length of thread engagement as when you install an OEM wheel. If you desire assistance with this matching just request lug nut inspection/ installation and the responding mechanic will walk you through all the requirements and assist you in selecting a vendor for the lug nuts. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Hello I recently hit a pothole and damgaged a rim I had. I had to replace with all new tires and rims. I first got stock rims then
ANSWER : A road force balancer is meant to check tires for pull in one direction or another and balance a tire up to about 60 mph. Some tire balancers will check tires for higher speeds. You may have an imbalance that most machines cannot measure if it comes in after 65 mph. You can see if there is a shop near you that can do high speed balancing? You may have a front axle that is causing the vibration also. I suggest installing the original rims and tires on the front only to see if problem is still there and if so have the front axles checked for damage and replaced if any damage or looseness is noted.

Driving while missing a lug nut and stud
ANSWER : Hello there, driving your 2014 Ford F-150 with a missing lug nut and wheel stud is not safe. Without all the lug nuts attaching the wheel it cannot be properly torqued in a safe manor. Your vehicle should not be driven until the wheel stud is replaced and the lug nut reattached. A qualified Technician such as one from YourMechanic will be able to inspect your wheel stud and make any repairs required to make your truck safe again.

Need help choosing the right rim size for my tire
ANSWER : Hi…Tire size 33 x 12.5R16 is equivalent to LT305/70R16. The recommended rim width is 8 to 9.5 inches with 9 inches being typical. Rim width is not the only critical dimension, you also have to be sure you have the correct rim offset in your application, especially if you are not using the factory OEM rim which of course already is built with the optimal offset for the OEM suspension. If you need further assistance with any issue relating to your car or truck, please let us know.

Can I drive with just one lug nut loose on one tire? The nut is stripped so I cannot take it off. But 3 out of 4 nuts are on tight
ANSWER : Hi there. I’ve seen many vehicles on the road with a lug nut missing and it does seem to work. However, what these people are unaware of is that improper/uneven wheel nut torque is a major cause of brake vibrations. The uneven/improper torque can cause the brake rotor/drum to warp. If the lug nut is loose, only drive it if you need and get the stripped nut replaced as soon as possible. I suggest having a qualified technician perform an inspection to determine if more than the lug nut needs to be replaced and avoid replacing unnecessary parts. Your Mechanic has several technicians available that can assist you with a check wheel nuts inspection.
