But there is a simple wat to find the wheel ET using measurements from the sidewall of the tyre.

Once you have done that, measure the distance from the floor to the straight edge. Make note of the number and divide it by 2. This gives you the centre line of the wheel. Now, measure from the straight edge to the inside of your alloy wheels. Make a note of that number too and subtract the number you measured for your centre line and the one you just measured.

Smallest number from the largest. When the centre line measurement is the smallest, it means you have a positive offset. In the vast majority of cases, a change of just 5mm to your offset it enough to affect the handling of your vehicle.

You should now feel more confident about knowing what wheel ET is and how to find out what it should be on your wheels.
