It is referring to the offset

What does ET35 offset mean?

ET35 is the offset - the distance of the hub mounting surface to the wheel's symmetry axle expressed in millimetres.

What is difference between et30 and ET35?

the offset numbers are actually millimeters and think of it working in reverse so that if an et30 sits flush with the fender then an et35 will sit more inside the wheel well by a difference of 5mm. The stock wheels being et43 will sit even further into the wheel well by 13mm more than an et30 wheel.

Is offset and ET the same?

The offset of an alloy wheel is the distance in mm between the centre of the wheel barrel to the mounting face that attaches the wheel to your vehicle. Offset is usually represented as an ET number, with the number noting how many mm is between the centre of the wheel and the mounting face.

Is ET positive or negative offset?

This gives you a 'backspacing' figure. Now all you need to do is subtract the backspacing value from the centre point figure, et voila: you have your offset figure. A positive figure means you have negative offset, while a minus number - as you've probably gathered - is a positive offset.

Does ET matter on wheels?

In practice, the ET-value is the number in millimetres that the centre line of the wheel deviates from the mounting surface (on the wheel hub). As a rule of thumb: the higher the ET, the more a wheel is positioned inwards; the lower the ET, the more a wheel protrudes outwards.

What does ET mean in wheel offset?

Offset is usually stamped or engraved into the wheel and is measured in millimetres of 'ET' [ET is the short form of the German word 'Einpresstiefe' which literally translates as 'insertion depth'] Positive Offset wheels have their mounting face toward the front face of the wheel.

What is ET38?

What do wheel offset numbers mean? Offset is expressed as an ET number, (ie is ET38) and the 'ET' is a shortened version of the German word 'Einpresstiefe' which means 'insertion depth. ' The number is the distance in millimetres between the centre line and the mounting surface.

Is 10mm Offset a big difference?

10mm isn't a huge amount. On some cars it makes little difference. Tough you say. But if you want exact fit...see if the dealer still make it right.

What is ET 25 Offset?

You will most often find this measurement moulded or stamped on your wheel, for example et25 or 25p. This would mean your mounting face is 25mm towards the outside of your rim from half of the wheel's width.

What is ET 44 offset?

“ET44” — the offset of the wheel mount from the center of the rim. This can be positive or negative. Negative is closer to the suspension. Positive is further from the suspension of the vehicle. “ET44” means a 44-millimeter positive offset or 44mm off center on the roadside of the rim.

What is JJ in rims?

JJ refers to the contour of the bead seat on the wheel, essentially its shape ( “J” indicates the shape of the letter J).

What is the difference between 7j and 8j wheels?

The wheels width is usually written beside the flange shape marking – e.g: 7j, 7.5j, 8.0j. The width of the wheel is basically the area shown on the photo above and it is measured in inches. In other words, the bigger the number, the “thicker” your wheels are.

What does 18x8J mean?

J: this is the width of the wheel from inner to outer rim in inches. so an 18x8J is 18 inches in diameter of course and 8 inches from inner to outer rim.

How do I know if my rims are aftermarket?

Look for a logo or the name of a wheel manufacturer imprinted on the back of the wheel. There might also be the size of the wheel, the offset, and the date it was manufactured, depending on the company that made it.

What does 9J mean on wheels?

Hi, J is the type of rim & 8.5 & 9 are the rim width in inches, so 9J is 1/2 an inch wider than 8.5J.

How much offset is acceptable?

Even if the tire and wheel have enough clearance, the wrong offset can decrease vehicle stability. Generally, with new wheels, you don't want the new offset to be more than 5 millimeters different from the old offset.

What is a 5'2 offset?

The second number indicates the distance from the mounting plate to the outer bead. For example, a 5+2 offset means there is 5” from the back/inner bead to the mounting plate, 2” from the mounting plate to the outer bead.

How far will offset stick out?

Well-Known Member. Yup.. - 12 offset. Sticks out sbout an inch.

What does et30 mean?

The “et30” in [17x9 et30 5×100] represents the Wheel Offset(millimeters). Now we're switching to metric. The wheel offset is a bit harder to explain. Looking at the picture here: We can see that with a “0 (zero)” offset, the point at which the wheel is bolted onto the wheel hub “splits” the wheel width in 2.

What does et 39 mean?

ЕТ39. ET is the offset, that is the distance between the centerline of the wheel and the plane of the hub-mounting surface of the wheel. The offset is measured in millimetres and can be positive or negative. In our case it is positive: 39 mm.

What is a 40mm wheel offset?

With the declared positive offset of 40, the wheel's mounting pad is located 40mm from the center line, towards wheel's front face, being 40mm from the center line position which is at 88.9mm.

What is positive offset on a rim?

Positive offset is when the hub mounting surface is toward the front or wheel side of the wheel. It is common to find a positive offset in newer and front wheel drive vehicles. Negative offset is when the hub mounting surface is toward the back or brake side of the wheels centerline.

What does H2 mean on wheels?

What does H2 mean ? This markings stands for the wheel hump, it usually appears at the very end of the wheel markings. It corresponds to the rigidity of the wheel. There are several wheel humps out there.
