Geometry & Clearance

Track width is the distance between the centers of the left and right tires on an axle. Changing wheel width, offset, or adding a spacer can move the wheel outward, inward, or both...

A lowered vehicle can change the practical result of a wheel swap even when the donor wheel’s offset appears suitable. Lowering changes ride height, suspension travel, camber, stee...

Same Wheel Width, Different Offset: How Far Will It Move? Two wheels can have the same width and still sit very differently on the vehicle. The difference is usually caused by offs...

How to Calculate Inner Wheel Clearance From Width and Offset To determine whether a donor wheel will sit closer to the suspension, compare it with a wheel that already fits the veh...

A wider donor wheel does not move all of its extra width in one direction. Where it goes depends on the change in offset as well as the change in wheel width. Part of the added wid...

How Wheel Adapters Change Effective Offset and Track Width A wheel adapter changes more than the bolt pattern. Its thickness moves the wheel’s mounting face away from the hub, whic...

Establish the reference wheel first A fender or widebody conversion changes the available bodywork clearance, but it does not automatically change the wheel’s position relative to ...

Scrub Radius Change: What Wheel Offset Does to Steering Changing wheel offset changes more than the position of the rim inside the arch. It also moves the tire’s contact patch rela...

A universal safe wheel offset difference does not exist. A wheel that is only 5 mm different in offset may fit one vehicle and cause suspension or fender contact on another. The re...

Wheel Width + Offset: How to Predict Inner Clearance and Outer Poke Wheel width and offset determine where a wheel sits relative to the hub. Width moves the inner and outer edges a...
