How to Read Wheel Offset & Measurements
Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.
ANKUSI Engineering Expert Advice
On a vehicle this heavy, the wheel is a structural part before it is a styling part - it carries the load, the brake heat and the cornering forces all at once. A forged wheel buys back unsprung weight without giving up the load rating an SUV actually needs, which is the one number most cast aftermarket wheels quietly fall short on.
We publish the factory specification for the Proton X70 below. We have not yet been able to verify aftermarket flush or maximum-aggressive offsets for this exact variant against a source we trust, so we are not listing any - an invented offset is worse than no offset when a wheel has to clear a caliper.
Proton X70 OE Wheel Specs
The 2018 Proton X70 (SUV) uses a 5x114.3 bolt pattern with a 60.1mm center bore. Factory wheels are 19x7J F/R.
Why the factory spec works for most owners:
- Keeps unsprung weight low to preserve the factory handling balance
- Matches the wider, performance-oriented tire sizing typical of this platform
- Maintains clearance for the factory brake package and suspension geometry
- Balances grip with ride comfort for daily and spirited driving
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Proton X70 (2018) we drill the 5x114.3 pattern and cut the centre bore to 60.1mm on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.

Aftermarket Fitment: Confirmed on Request
Published aftermarket fitment for this exact variant is still thin, so we have not committed to a flush or maximum-aggressive figure. Our engineering team is still collecting verified data for this variant. In the meantime the factory specification above is accurate and is the safe reference point for ordering.
What we do know: Generation I, model years 2018-2023. Verified against two independent fitment references.

Proton X70: Specs by Model Year
Vehicles With the Same Hub as the Proton X70 (5x114.3, 60.1 mm Bore)
In our database, 216 other vehicle entries from 18 makes use exactly the same 5x114.3 bolt pattern and 60.1 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.
5x114.3 is used by 20.0% of the vehicle pages in our English fitment guide (1,300 of 6,503); 16.8% of those also use a 60.1 mm center bore.
Hub-Centric Rings for a 60.1 mm Center Bore
A wheel with a center bore larger than 60.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 63.4 mm | 63.4 → 60.1 mm |
| 64.1 mm | 64.1 → 60.1 mm |
| 65.1 mm | 65.1 → 60.1 mm |
| 66.1 mm | 66.1 → 60.1 mm |
| 73.1 mm | 73.1 → 60.1 mm |
ANKUSI forged wheels are bored to exactly 60.1 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Proton X70 use?
The 2018 Proton X70 uses a 5x114.3 bolt pattern.
How many lug bolts does the Proton X70 use?
The Proton X70 uses a 5-lug bolt pattern (5x114.3), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Proton X70?
The Proton X70's center bore is 60.1mm. If an aftermarket wheel has a larger center bore than this, hub-centric rings are recommended so the wheel centers on the hub itself rather than relying on the lug bolts alone.
What size are the factory (stock) wheels on the Proton X70?
Factory wheels on the Proton X70 are 19x7J F/R.
Do I need wheel spacers for my Proton X70?
No. ANKUSI forges each wheel to your exact target offset, including the flush or max specs above, so you get the correct fitment without stacking spacers. Spacers are typically only used to push out an existing OE-offset wheel without replacing it, which isn't necessary when you're ordering a custom-offset forged wheel.
What's the difference between wheel offset and backspacing?
Offset is the distance in millimeters from the wheel's true centerline to its mounting face (positive offset pulls the wheel in, negative pushes it out). Backspacing is the distance in inches from the mounting face to the back edge of the wheel barrel. They describe the same fitment from two different reference points, which is why ANKUSI lists both above — some shops and tuning guides quote offset, others quote backspacing.
Can I run staggered wheels (different sizes front and rear) on my Proton X70?
The Proton X70 runs the same wheel size front and rear from the factory, so staggered fitment is not required. ANKUSI can still forge a staggered set (wider rear) on request if you want a more aggressive stance.
