Will this rim fit?
Enter your stock wheel and the wheel you're considering. We'll show exactly how far it moves in and out, and whether the hub fitment matches.
Won’t fit as-is
The wheel’s 73.1 mm center bore is smaller than the 87.1 mm hub — it won’t sit on the hub.
The wheel face pokes out 21.7 mm further — check fender clearance and rubbing at full lock and compression.
More than 15 mm of extra poke usually needs fender rolling or a lower-offset tire choice.
Inner clearance change
+3.7 mm
closer to suspension
Outer poke change
+21.7 mm
sticks out further
Backspacing
5.98" → 6.13"
+3.8 mm
Diameter
17" → 18"
choose a tire with a shorter sidewall to keep the same overall diameter

Frequently asked questions
What is wheel offset (ET)?
Offset is the distance in millimetres from the wheel’s centreline to its mounting face. Higher positive offset pulls the wheel further under the car; lower offset pushes it out toward the fender.
How do you calculate poke and inner clearance?
Half of the width change (in mm) is added to both sides. The offset change then shifts the whole wheel: inner change = width change ÷ 2 + offset change; outer change = width change ÷ 2 − offset change.
What is backspacing?
Backspacing is the distance from the mounting face to the inner lip. It equals half of the overall wheel width (rim width + about 1 inch for the flanges) plus the offset converted to inches.
Can I use a wheel with a bigger center bore?
Yes — a larger bore is fine with hub-centric rings that fill the gap. A smaller bore will not fit over the hub without machining.
