Backspacing and Offsets might seem a little confusing for the first time, but understanding them is extremely important for the accurate fitment of your wheels and tires. It’s never a good idea to buy something without having complete knowledge about it, especially when it is related to your safety and comfort. We at Wheels and Tires Packages wants you to understand your vehicle before making the purchase. Here we have simplified the definition of backspacing and offset for you. 


Backspacing is a way of locating the depth of mounting Pad in the Wheel. To have proper backspacing is essential because it provides enough space for the internal system, including the suspension and brakes for smooth operations. The best way to measure the backspacing is to find the difference between the Wheel’s mounting surface and the deepest point of extension of wheels. 

Understanding backspacing will help you to utilize your wheels to the highest potential. It is significant while lifting your suspensions, and it impacts the backspacing of your vehicle.

Easy Way to Measure Backspace:

  • Lay your wheel down with its backside upwards.
  • Take a straight edge and place it diagonally across the inner edge of the wheels. 
  • Measure the difference between where the straight edge contacts the inboard flange.


Wheel Offset is different from backspacing. Wheel offset is the measure of space between the center of a rim to its mounting face. If you have more offset, your wheels mount inwards and provide more clearance. Wheels offset decides how the rims mount in your Wheel wells and it shows the amount of space you have on a single side of the wheels. The wrong offset can cause a lot of trouble, causing problems with your suspension, brakes, and other parts. 

Zero Offset: In zero offset, the mounting surface of the wheel is on the centerline. The centerline is the innermost end of your wheel if you were slicing it down the middle vertically.

Positive Offset: In positive offset, the mounting surface is towards the front. Front-wheel drive vehicles generally have positive offset and it is very common. Too much of the positive offset can make your car unstable and increase the risk of failures.

Negative Offset: In case of negative offset, the mounting surface of the wheel is tucked back closer to the inside edge of the wheel, which offers less backspacing. , and a more “dished” wheel, popular in show cars and trucks. More negative offset puts additional stress on suspension and will affect the handling of the vehicle.

We hope this piece of information will help you to get a better idea of Off Set and Backspacing. Understanding the basics of your wheels and tires facilitate your decisions about buying the right wheels and tires. If you still have any questions, please contact us and ask for advice.
