One more time this is how you measure the wheel offset on your vehicle. Remove the wheel and accurately measure the width.

Wheel Offset And Backspacing Explained Custom Offsets Wheel Custom Wheels Trucks Custom

Wheel Offset is the measured distance between the hub mounting surface and the wheels center line.

How to measure wheel offset. Take the measuring tape and measure the distance from the rule to the hub mounting pad in inches. If for some reason your wheel doesnt have an ET number you can measure it by yourself using some easy steps and some simple wheel offset calculation. To put it simply wheel backspace is the distance between the mounting plate and the wheels flange.

To measure backspace you can just use a ruler or measuring tape to find the distance from the rear of the wheel well to the tire. Wheel Offset The offset of a wheel is the distance from the hub mounting surface to the center line of the wheel. More about custom wheels.

You then subtract the distance from the hub to half the width of the rims. Its one of the important alloy wheel measurements. A wheels width is from the mounting points of the tire beads therefore the measured width of a wheel from outside edge to outside edge is about an inch wider than spec.

The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. In this short tutorial I show you how to measure offset using my 17 OZ Fittipaldi 3 Piece wheels as an exampleSteps1. Measure from any bolt to the outside edge of a bolt on the opposite side for a 5-lug rim.

How to measure alloy wheel offset Offset is the distance from the hub-mounting surface to the wheels true centreline. As a rule such setup may be found on the rear-wheel drive vehicles. Typically speaking the higher the offsetbackspace the more the wheel will tuck inward towards the suspension or away from the fender.

Determine the wheel backspace measurement. Then choose 1 of the 2 bolts on the opposite side. Wheel Backspacing is the measurement from the hub mounting surface to the back edge of the wheel.

There are 3 main types of offset. Thats when the hub mounting surface is aligned with the wheel centerline. An 8 wheel will measure 9 from side to side this makes converting offset to backspacing not so straight forward.

This is a combination of the width and the offset of the wheel. A wheel with 5 lugs wont have a symmetrical set of bolts. Find the centerline of the wheel.

When you purchase a new vehicle theres a good chance it will have a slightly positive offset. Total wheel width was measured at 295275mm thus Center Point is 1476375mm. Jack the car up.

Wheel Width Measuring the Wheel width is similar to measuring the Diameter. Measure the overall width of the wheel in mm Find the centre line of the wheel exactly half of the overall width. Zero offset would mean the hub mounting surface is.

To measure a 5-lug rim place the hook of your measuring tape in the middle of a bolt. Your result is the wheel backspace. 3-Steps to Measure Wheel Offset.

Wheels with negative offset or so-called deep dish wheels have got the hub mounted closer to the back side of the wheel. Measure from the centerline to the mounting hub and record it in millimeters. You will want to measure from the Barrel Section and not to overall outside width See Picture Below.

To measure the backspace start by laying the wheel on a flat and stable surface. Before you measure the wheel offset there is one value that you should determine wheel backspace. Depending on where the hub-mount is this number can be either positive or negative.

Wheels that have positive offset have the hub mounted toward the front side of the wheels. Place a ruler or tape measure perpendicular to the straight edge near the center of the wheel. Then look at the ruler or measuring tape to find the measurement at the bottom of the straight edge thats laid across the tire.

To measure offset you must measure the width of the rims and then measure the distance from the hub to the outside of the rims. Nearly every wheel has the offset stamped on it somewhere usually ingraved on the wheel as a part of the wheel markings eg 6½ J x 15 H2 5112 ET39 - ET39 means 39mm offset and its measurement unit is millimeter mm. This is done by laying the wheel face down so the back is facing up towards you.

Position the straight edge so it is near the center of the hub with 1 end touching the floor under your tire. Lay your ruler across the inboard flange. Given this it can be one of three types.

Remove the wheel and accurately measure the width.
