It may not be common knowledge, but tape measures are made with the measurring "hook" on the end having intentionally slotted holes so that you can get an accurate reading when grabbing the outside of and object, as well as when butting the hook up to a flat surface as in this instance which pushes the hook against the nearer side of it's slotted holes.

This is not just a 30 second explanation of what the measurement is. It is a lesson in HOW TO MEASURE--the title of the video. Nothing he said was slow. I think it was necessary for him to point out what to avoid doing that could result in an inaccurate measurement. Attention to detail is crucial when measuring things. If you're going to teach someone to do something, teach them to do it right the first time.

Lord grant him wings to get quickly to the point!

The hook on most tape measures have a little play in the rivet. So that it compensates for the thickness of the hook. When you push the end of the tape to measure, the hook moves in. When you hook the the tape and pull, it moves out. Exactly the thickness of the hook. Therefore it's accurate using either method

This guy should work for the govt. His 'change a spark plug video' must be an hour and a half long...

Tape measure end moves according to how its used. It moves in when you butt up against object and moves out the thickness of the end when its clipped on to an object. my 2 cents

Another way to look at it is this, if you were to cut off the portion of ruler that shows no graduations (markings) at all, this would drop the ruler deeper in the wheel during the initial measurement, effectively ADDING that 3/16” back to the graduated portion of the ruler. Thanks for commenting, we appreciate your input!

subtract and add It should be 30 Sec show

You add 3/16 of an inch because the measuring lines do not start at the end of the ruler, this shifts the number up and off of the mounting point of the wheel 3/16 of an inch. To compensate, you must add the 3/16s back into the measurement.

That dude you meet at the bar where you excuse yourself to the bathroom and leave out the backdoor... Kidding, kidding, I appreciate the video actually.

it took you 6 1/2 minutes to explain something that should have taken 30 seconds

There's 6.30 minutes of my life I won't get back!!!!!!!!!!!!!!!!!!!!!!!!!!!

You didn't cover negative backspacing... I thought backspacing was measured to the centerline of the wheel? Are there multiple ways to do it?

The comments sound like an SNL skit. Are these people for real? LMAO

Seams like you really did this the hard way. PUT A FLAT EDGE ON THE INSIDE OF RIM LIP. MEASURE WITH TAPE MEASURE FROM THE THE FLAT EDGE TO THE HUB MOUNTING POINT, and your all done.

Put the rim on the garage floor and measure it , unless you milling your own rims they usually only come in 6 , 6 .25 , 6.50 , 6.75 , 7.00 , so on and so forth , most dont even have 4 different widths to choose from , usually only 2 , ....jmo

The problem here is I don't believe you can get a rim with 7 9/16" backspace!!!

did you say AXE. often axed question. you are the first white guy to say axe a question

Dude go Metric, no fractions!

Good info. It gets real confusing when it's listed as offset in MM. Looking to get some 18x9 wheels that will fit my 64 chevelle it's a pain.

Where is the part number stamped on a draglite? How can you tell the width and backspacing on a wheel with a tire, on the car? Or can you? Or, do you need to take the wheel off the car to get the B's and strip the tire off the wheel to measure the width accurately?

It took this guy 6 minutes to explain it wrong... I don't know about everyone else but I've always measured backspace to where the tire seats not the edge of the lip..

Backspacing is not problem but how do I figure out the remaining rim facing outward? Since backspacing takes into account the inner lip of rim does the difference also take account of the outer lip?

Why not get a ruler that is "right on," instead od 3/16 in. off??

Wouldn't you subtract the 3/16 since the the ruler will be held this much higher off the rim...

Summit Racing, what is the advertised backspacing of this wheel in comparison to the actual measured backspacing?

Too much redundant talk...

Thank you so much for sharing this specially from professional 😎 I have a gmc 86 and I want to order rally wheels from summit racing but there’s two kinds of wheel back spacing 4.25 and 5 !!! Can you tell me please what should I buy for the front and back?

Lol had to think about that one for a sec too. A bigger space gives you a shorter reading so you have to add it back.

You have to subtract the distance the ruler started at which in this case is 3/16 on an inch. Do Not Add 3/16 You subtract it.

have a 15 x10inch rim. what would back space need to be to keep inside fender walls for a 1982 s10 truck.

one hes wrong its not 7 3/8ths 2nd with tire on, measure from wheel rim to straight edge and subtract that..simple!!

Just get to it buddy!

Who else fell asleep watching this gotdang video!

So then ask yourself, If you call Summit or Jegs or whoever, and say you want a WELD wheel with 7-9/16 back space, he will tell you they don't fuckin' make them in that increment.

15 inch rims are 16 1/4 x 7 3/4 18 inch rims are 19 1/2 x 2 This sound right? Asking for a friend

zoom to 4:45 for the answer.

Why can't we just measure it with the tape measure?

Just watch Coker Tire video. Explained in less than 60 seconds.

What is the purpose of backspacing what is the purpose of backspacing

who else had to watch this video like 3 times cuz you just got lost and didnt know what he just said?

For those of you who can't get past the extra space on the ruler.... think of it this way... You are subtracting the length of the ruler... (to cut off the extra portion) Therefore it creates more reading on the other end where it's measured... So both are really correct... subtracting length of the ruler... causing an addition to the actual reading. It doesn't mean anyone is dumb... People are so mean.... they think they are so smart... they probably voted for ObamaCare...

Let's not over complicate this now....The don't come in 1/16ths so...dayum boy get to it

Spose to subtract the 3/16

I understand how you must add the 3/16 of an inch to the measurement when using the fixed ruler, but when viewing the video It looks like the yellow tape measure is at almost 8 inches. 7 and 9/16 is just over 7 and 1/2 inches (close to 7 and 8/16). Why does the yellow tape measure appear to be at almost 8 inches?

Get to the point! He must get paid hourly...

you took to long just to show a simple task.

This could have been a 10 second video.... I think we all know how to use tape measures and rulers. Thanks for the info anyway.

All I can say is get to the point already!

Wake me up when he finally gets to the point 😴

This clown is telling us how to measure backspace and he don't even know how a measuring tape works .

Holy fuck man, get on with it. 1 minute tops.

off set,,, offset

Wholly crap..... Blah blah blah blah blah....... This video should have takin 45 secounds

Drained get to the point

Start at 4:45 all that before is BLAH BLAH BLAH.....

lol

duuuu
