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
Hot hatches and performance compacts are built around quick direction changes, so rotational mass at the wheel has an outsized effect on how the car actually feels to drive. Forging trims that mass while holding the same strength margin as the factory wheel, which is exactly the trade-off this kind of platform rewards.
The Seat Altea 1.6 runs a 5x112 bolt pattern, 57.1mm center bore, and a 15x6.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 18x8.0J ET40, which tucks the tire under the fender lip on a stock-height Seat Altea 1.6. Our Maximum Aggressive reference is 18x8.0J ET35 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Seat Altea 1.6 OE Wheel Specs
The 2005-2008 Seat Altea 1.6 (Hatchback) uses a 5x112 bolt pattern with a 57.1mm center bore. Factory wheels are 15x6.0J F/R.
Why the factory spec works for most owners:
- Balances ride comfort with everyday fuel efficiency
- A widely used size in this segment, so tire and wheel availability stays strong
- Keeps unsprung weight low for stable, predictable handling
- Maintains clearance for the factory brake calipers and suspension components
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Seat Altea 1.6 (2005-2008) we drill the 5x112 pattern and cut the centre bore to 57.1mm 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.

A Note on Clearance
Final clearance depends on the exact tire model, suspension height, brake package, alignment and vehicle tolerances. A physical test fit is recommended before production.
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Seat spec, or want a wheel built to a custom offset for your Seat Altea 1.6? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Offset and Backspacing: Factory Wheel vs Options
Backspacing ≈ width/2 + ET/25.4 + 0.5 in. "Inward" means closer to the suspension; "outward" means closer to the fender lip.
| Setup | Size | ET | Backspacing | Inward vs OE | Outward vs OE |
|---|---|---|---|---|---|
| Factory (OE) | 15x6J | ET50 | 5.47 in (139 mm) | — | — |
| Flush | 18x8J | ET40 | 6.07 in (154 mm) | +15 mm | +35 mm |
| Maximum | 18x8J | ET35 | 5.88 in (149 mm) | +10 mm | +40 mm |
Vehicles With the Same Hub as the Seat Altea 1.6 (5x112, 57.1 mm Bore)
In our database, 407 other vehicle entries from 18 makes use exactly the same 5x112 bolt pattern and 57.1 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.
5x112 is used by 21.6% of the vehicle pages in our English fitment guide (1,407 of 6,503); 29.0% of those also use a 57.1 mm center bore.
Hub-Centric Rings for a 57.1 mm Center Bore
A wheel with a center bore larger than 57.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 60.1 mm | 60.1 → 57.1 mm |
| 63.4 mm | 63.4 → 57.1 mm |
| 64.1 mm | 64.1 → 57.1 mm |
| 65.1 mm | 65.1 → 57.1 mm |
| 73.1 mm | 73.1 → 57.1 mm |
ANKUSI forged wheels are bored to exactly 57.1 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Seat Altea 1.6 use?
The 2005-2008 Seat Altea 1.6 uses a 5x112 bolt pattern.
How many lug bolts does the Seat Altea 1.6 use?
The Seat Altea 1.6 uses a 5-lug bolt pattern (5x112), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Seat Altea 1.6?
The Seat Altea 1.6's center bore is 57.1mm. 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 Seat Altea 1.6?
Factory wheels on the Seat Altea 1.6 are 15x6.0J F/R.
What is the biggest wheel size I can fit on my Seat Altea 1.6 without rubbing?
The most aggressive fitment we recommend without fender work is 18x8.0J at ET35 offset. Going beyond this typically causes rubbing under compression unless you roll the fenders or add camber correction.
What does a flush wheel fitment look like on the Seat Altea 1.6?
For a flush look with minimal to no rubbing, we recommend 18x8.0J at ET40 offset as a starting point on a stock or mildly lowered Seat Altea 1.6.
Do I need wheel spacers for my Seat Altea 1.6?
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.
How do I calculate wheel backspacing for my Seat Altea 1.6?
Backspacing (in inches) = wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance). For example, the flush spec above works out to roughly 6.07" of backspacing.
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 Seat Altea 1.6?
The Seat Altea 1.6 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.
