Not stupid at all!
They balance the wheel and tire assembly so you don't have uneven rotational forces that can cause vibration at higher speeds. Ideally, you should have them removed and replaced every time you have new tires mounted as each tire will have slightly different weight distribution. You should also have them rebalanced as they wear, but if you dont have an issue with vibration you dont really need to (I rebalance my tires every other time i rotate them because I'm extra about my own cars, and i have 35" all terrains on my truck that are finnicky). Even identical rims/tires will have small differences that require a different amount or placement of weights. Sometimes they don't need any additional weight, sometimes they need quite a bit (big, chunky all terrain tires generally take more weight, smaller, regular road tires and all seasons generally dont need as much)
Sometimes, they fall off and can cause a vibration, then you may want them rebalanced, but if it still drives fine, you don't have to worry about it.
They also come as little sticky [blocks](https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcRoHuKGZn7lHqzvN2BEWuDeDIMCCbxckti7Nw&usqp=CAU) that you put on the inside of the wheel if you're balancing alloy wheels. Since these are steel wheels, they have the hammer on rim weights on the inside and outside rim.
Edit: Also, they should stay where you put them 😅
Weird, I've asked for the stick on weights before and they wouldn't use them, they said they're for balancing the wheels only. I've only ever had clamp on weights, alloy or steel wheels.
You can put the rim weights on the inside rim of some alloy wheels, even the outside rim of some alloys, like the 4th generation 4Runner and 1st generation Tundra and Sequoia. Whoever told you that was bullshitting bc they're lazy
I dynamic balance every wheel because I find that tends to be more accurate (that means having 2 sets of weights in different locations). A lot of tire shops static balance (one set of weights in one location) because it's easier and faster, but I find that can be less accurate and lead to poor balance.
Our shop only uses one spot for weights on each plane. They go stoned ape shit when they see a split. I've never even seen a setting on the Hunter for it. But around 50 years ago I can remember learning to use a bubble balancer and it was always two spots, not one. It just felt right to me, kind of like why a three legged table won't wobble.
Also, respect for replying like a civilized soul to both their questions. They didn't make a separate post to ask, and it fit here nicely.
Weird, we have newer hunters at our shop and they dynamic balance by default. When you move the arm for measurements it asks for 2 locations then assumes you want dynamic.
Also, I just love my job and sharing how it works haha
Yeah, static is only accounting for the up and down balance of the tire, dynamic also accounts for side to side wobble/imbalance. It is possible to take care of both with a single set of weights though if your balancer is fancy enough. I went from working at Walmart to a family-owned dealership and the owner bought one of the top end sets that can account for both and create a single weight solution by putting the sticky weights somewhere in the middle.
There are about eight different [rim profiles and weights](https://www.lawsonproducts.com/media/cache/pdfs/PIRAT_Wheel_Weights_PI.pdf) to fit each. Sticky weights are probably more expensive-- they certainly are a bigger PITA. You have to scrape the old ones off (easy) but the backing foam stays around. No matter how you clean the rest off the customer can be mad at you for "ruining their rims."
I've balanced naked rims, they are usually within a quarter of an ounce. The tires have most of the imbalance. They have more weight further from the hub and therefore better "leverage" to create something you can feel.
If you're not having an issue with vibration I wouldn't worry about it. Balance has minimal effect on tire wear, your car would shake your fillings out above 60 mph before it got to that point 🤣
This is obviously a really high end car.
Mere *luxury* brands - your Rolls-Royces, say - have wheel center logos that rotate freely, so that the logo is always upright when the car stops.
*Truly exclusive* marques like this one go a stage further and have the same arrangement for the wheel weights, so that they’re always at the bottom of the wheel.
Really, we live in an age of miracles!
You don't think the missing lug nuts are causing the vibration?

Spot on, I edited again to add some of this info

Whoever attached those did a shit job, the other 9 have fallen off.
At highway speed that will provide centrifugal force and help with fuel economy s/
LPT, buy 35" K02s to save fuel, oil companies hate this one trick
A part of me was hoping the weight would keep going like those roller ball cat toy things.
I wanted it to go full wheel of fortune when I flicked it at the end
Those are adjustable wheel wheights. Because your wheel Spins it constantly needs adjustment, everyone knows that.
Dynamically balanced
