Adapter Thickness + Wheel Offset: How to Avoid Excessive Poke An adapter moves the wheel outward, while wheel width and offset determine where its inner and outer edges sit. To est...

Start with the wheel’s reference position A spacer sits between the wheel and the hub, moving the whole wheel outward. It does not change the wheel’s width or shape. Its effect on ...

Establish the reference wheel Use a wheel whose fitment is known on the exact vehicle configuration you are evaluating. The strongest baseline is usually the wheel currently fitted...

Start with the wheel that fits Use the current wheel and tire as your reference. Record the wheel width and offset, tire size, and the location of the tightest inner clearance. Che...

A wheel that clears the rear axle may still contact a front brake caliper, suspension part, or fender. The front and rear can have different hardware and available space, and the f...

Start with the wheel currently on the vehicle Poke is how far a wheel’s outer edge sits outward from the hub mounting face. To estimate a donor wheel’s change in poke, compare it w...

A wheel that clears the fender and suspension while parked may still rub when the suspension compresses or the steering turns. Static clearance is only a snapshot: the wheel and ti...

Start with the reference wheel After a brake upgrade, a wheel that used to fit is a useful reference–but it is not proof that the wheel still clears the brakes. A larger rotor can ...

Start with the wheel that was on the vehicle After installing adjustable suspension arms, reassess fitment rather than assuming the previous wheel position still works. Depending o...

Start with a reference that already fits The best basis for a fender-rub prediction is the wheel and tire currently on the vehicle. Record their width, offset, tire size, and the s...
