Good video, explained in a manner that anyone should be able to understand. You are 100% correct that the width of the wheel is moot in this vid............. Offset is being determined.
Interesting subject. Seems a bit confusing for some but not others. So offset is a relative figure of measurement, that is the distance from inner mounting surface to the centerline of the wheel, either positive or negative, and thus whether a tire is mounted is irrelevant (assuming perfect tire symmetry and measurement), correct? Good video. The fact that some (including myself) struggle with the concept is good. This is evidence of learning and/or correcting mistaken beliefs. Good work Driftworks!
i have the offset printed inside my wheel of 15 after measuring your way i got 22. figure what went wrong was instead of measuring from inside hub mount to inside edge i measured from inside hub mount and brought it to the face of the wheel.
Hey Phil, Does the fact that there is a tire on the wheel cause issues with your measurements? Or is the issue negated because all the measurements are taken with the tire on the wheel?
Can someone please tell me what, "Inset" is? My Subaru specs says "Inset" is 55mm. Does that mean a 55mm positive offset? I thought you subtract the smaller number from the larger number = "Offset." He says it backwards. However, it seems to me that "Inset" and "Outset" are more accurate terms, but IDK. If you subtracted center from hub = 122 - 175 = -53 (AKA a positive offset of 53). ?? so, inset seems to mean a "Positive offset" because that -53 would mean the wheel sits inward by 53mm, i.e., -53mm from the fender line/on the axle end. So if a hub measured 120, then 122 - 120 = 2mm. A positive number, meaning the wheel would sit 2mm out from fender line/2mm farther out on the axle end. ?? AKA a 2mm "Negative offset." Confusing to me
Can some one help me read what is the off set of this? Looking at a rims in a website “11-mm with 4-mm off set” it doesn’t say negative or possitive ..
seems counter-intuitive but it makes sense - all you need to find is where the centre of the rim is, even if tire sticks out from the rim it sticks out equally from both sides .
I got a width of 160mm (which means the width center is 80mm) BUT I also got 80mm for the second measurement (from the wheel side to the mount surface). If I subtract 80mm from 80mm I get zero. But that isn't possible according to this video. It should be positive or negative something - never zero? What should I do?
You could also google the name of your rim, find the manufacturers website and most likely find the different sizes along with spec data like ET measurements. Otherwise check the TÜV / ABE, if your rim is approved by that. Given this data is not forged into the actual rim itself.
Jones Nobs So I presume you didn't watch the video?... With the particular wheel we're measuring (ADV.1), the manufacturer never divulge offset information. Also there are plenty of occasions where you have an older wheel, and there is no offset information available anywhere online, and the manufacturer no longer exists. This video is to show you what to do when you have exhausted all other lines of investigation.
***** I did watch the video. But this should be a last resort, as it can easily become inaccurate. And if you are really trying to push your concave or alike, you could end up having a bad day, with the wrong numbers. I wasn't trying to be negative.
+Kevs Rev C Hi Kevs, have a look at www.willtheyfit.com where you can have a play about with different wheel sizes and offsets and it will tell you how they compare
I might sound stupid but I wanted to to know does the offset of an aftermarket wheel have to match the offset of the original cars spec? So the car has an offset of 45 and the wheel I am getting has offset of 30 would it still fit? If so are there any implication of doing this too? Thanks if any1 could help
Were you not supposed to measure just the rim without the tire? The edge of the tires add more length. So you got the offset for tire and wheel combined, but not for just the rim itself.
Did you watch the video Sergio? This is explained in it. The offset is measured from the centreline, so as long as the lip thickness is the same on the inner and outer part of the wheel, the offset measurement is still accurate using this method.
If you measure from the end of one side to the other end of the width of the rim, don't you have to subtract 1 inch of width from your calculations? Example: On Work wheels, the width isn't measured from lip to lip, but it's measured from tire seat to tire seat. A Work wheel that is 9" wide is officially 9" inches wide when measured from tire seat to tire seat, but if it was measured from lip to lip it measures out to be 10" inches wide, which is incorrect. This plays a hugh role in accurately determining the offset.
Todd Lee he wasn't measuring lip to lip. He's measuring from outer edge to outer edge and then from outer edge closest to where the rim would contact the mounting hub. cocomponents.com/dealer/blog/wheel-offset-explained/
Dale Chung yes I know that. With Work wheels it's measured from tire mounting seal to tire mounting seal, not outer edge to outer edge. If this method was applied to a Work wheel, the the offset would be completely off. Any who, that wheel that's measured in the video isn't a Work wheel, do maybe I'm just talking to myself.
Todd Lee We're not talking about your measuring wheel width here, we're talking about working out the offset. It makes no difference if you're measuring outer edges or inner lips as long as you're measuring them both the same. The offset is correct and will be correct for any type or brand of wheel. Offset is the difference between the centre of the wheel and the hub mounting face. It doesn't matter whether you use the inner rims or the outer lips to work out the middle of the wheel.
I don't see what good it does to measure a wheel that you already have. The trick is to figure out the required offset when you only have the tire to work with as this is the more likely scenario since you don't typically have the wheel before hand.
It gives you a start point if you don't have the offset information printed or engraved on your wheel. Most cars come with wheels fitted, and this allows you to accurately determine the specs you want if you're looking to change your wheels. In this case we were measuring these wheels on the Lambo to spec some new Work Wheels that sat exactly 14mm further outboard, and this measurement method mean't we were absolutely spot on with our new specs.
My issue with this is, if I'm buying new wheels they aren't measured with tires on, so the offset on the wheel indicated on the website is the size of the wheel itself. Not a wheel and tire. So even if I wanted to compare the offset of my wheel to a wheel online, by using this math, it would not be a direct comparison and I wouldn't be able to make a correct decision. Even if I was wanting the same size and width but different offset. Yes this does tell me what my offset is with the wheel AND tire on but that doesn't directly compare to the offset of the wheel which is what will be listed online. So yeah this isn't helpful at all in my opinion if you're actually looking to change your wheels and want a different setup or even the same setup. If I measure my wheel and tire like that and get a +53, and I go to order a wheel from a website that says it's a +53. It's actually going to be different once a tire is put on it because the +53 on the website is the offset of the wheel alone. Which if I remember correctly is measured from bead to bead, not outer edge to outer edge.
The offset is the offset regardless of whether a tyre is fitted or not. What you need to factor in is wheel width is measured between the tyre mounting beads, not the external width.
@@AdrenalineJunky17 I don't understand. This video shows you how to measure your wheel offset. It's worth watching again as I talk about how it doesn't matter that you are measuring from the outer edge of the lips. The offset measurement is the same. In the video I measure a 13j giving the exact mm perfect wheel offset.
@@driftworks so if I look up that exact wheel online will the offset the be the same as what you measured with the tire on? Measuring from edge of tire to edge of tire on the ground?
An actual clear and concise explanation, thank you Phil!
After watching this video I figured out how to measure an offset.
It is super easy, barely an inconvenience.
It sounds like you've watched some of Ryan's videos 😂
Thanks! I used your video as a guide and measured my offset before ordering a replacement wheel. Very helpful.
Great! I'm glad is was helpful 👍
best video I've seen on how to measure offset! thanks bro!
Thanks Emil!
@@driftworks Great video. My main issue is how do i find out WHICH offset wheel i need for the car. Can you explain how this is done ?
@@biasb3882 Measure the offset of your existing wheel that does not pass thru the fender and match that up with the new set which you intend to buy.
A clever and simple way to measure. Just need to make sure the ground is even enough not to distort the measurements.
Finally got this, cheers man 🔥
Cheers Phil for making this 6 years ago! Just came in handy
Only best easy explanation, you a legend mate

Hey Phil,
Does the fact that there is a tire on the wheel cause issues with your measurements? Or is the issue negated because all the measurements are taken with the tire on the wheel?
Hi, no, as mentioned in the video it doesn't effect the measurement 👍
Are those magnets too much or its normal weight for valancing a wheel thanks in advance cheers
on the higher end but as long as it's balanced it doesn't matter too much
Great vid

It can absolutely be 0. Lot's of wheel are 0 offset.
@@driftworks Nice - thank you!
So this would mean it is a ET+53 offset right? Because i taught that offset was measured in inches.
Yep, Offset is always measured in mm
When buying alloys, my manufacturer spec is 43 mm, alloys i want come in 42mm, will 1mm make a differance when fitting??
No it won't as long as the width is exactly the same.
I have a 2017 durango and I can’t get the accurate et for a 24 inch forged rim so it can be positive

Driftworks You're right. My brain farted.
My brain farted aswell, thanks!
I thought that you are supposed to measure the wheel width from bead seat to bead seat, and not the outside edge of the rim.
You are, but we're not measuring wheel width. We're measuring offset.
Thank you very much
You are welcome.
Thanks
No problem
PIMP dude, thanks!
what car is that ? doesn't look like anything familiar
Looks like the rear quarter of an LP640 murcielago to me
I guess so.Looks damn nice though!
Would an offset of +22 and a width of 10.5 make me rub? On my honda accord
10.5 on an accord? For why?
Seeing as my honda accord came with 15x7s. Yes im pretty damn sure youre going to have issues

I don't think it matters because you can have the same offset for different width of wheel, so finding the center line number is what matters.
