Fitting Seat Ibiza Ecomotive wheels? This page gives the 2011 Seat Ibiza Ecomotive bolt pattern (5x100), centre bore, factory rim size and the offset range for aftermarket and forged Seat Ibiza Ecomotive rims: the same spec sheet ANKUSI uses when machining forged wheels for this car.
Quick answer: The 2011 Seat Ibiza Ecomotive uses a 5x100 bolt pattern with a 57.1 mm centre bore and M14x1.5 lug bolts. Factory wheels: 15x5.5J ET38, front and rear. For aftermarket wheels, 18x8.0J ET35 front / 18x8.5J ET35 rear sits flush and 18x8.0J ET35 front / 18x8.5J ET35 rear is the most aggressive fit.
Forged wheels for the 2011 Seat Ibiza Ecomotive — drilled 5x100 with a 57.1 mm centre bore, built to the offset you choose. From $220 per wheel, made to order in about 25 days.
Seat Ibiza Ecomotive (2011): 5x100 bolt pattern, 57.1mm center bore. Factory wheels: 15x5.5J at ET38 offset, front and rear. Reference fitment ranges.

| Configuration | Wheel Size & Offset |
|---|---|
| Factory (OE) | 15x5.5J F/R |
| Flush Fitment | F 18x8.0J ET35 / R 18x8.5J ET35 |
| Maximum Aggressive | F 18x8.0J ET35 / R 18x8.5J ET35 |
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.
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 Ibiza Ecomotive runs a 5x100 bolt pattern, 57.1mm center bore, and a 15x5.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 18x8.0J ET35, which tucks the tire under the fender lip on a stock-height Seat Ibiza Ecomotive. Our Maximum Aggressive reference is F 18x8.0J ET35 / R 18x8.5J ET35 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
The 2011 Seat Ibiza Ecomotive (Hatchback) uses a 5x100 bolt pattern with a 57.1mm center bore. Factory wheels are 15x5.5J F/R.
Why the factory spec works for most owners:
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Seat Ibiza Ecomotive (2011) we drill the 5x100 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.

For a flush look, F/R 18x8.0J ET35 is a commonly used starting point — clearance must be verified on a stock or mildly lowered Seat Ibiza Ecomotive.
F 18x8.0J ET35 / R 18x8.5J ET35 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

The examples below are compiled from typical ANKUSI customer configurations and are labeled as reference cases, not individually verified real-world builds.
Case 1: Daily Driver (Factory-Style)
Profile: Everyday driving, prioritizes comfort and low running cost.
Setup: F 15x5.5J ET38 / R 15x5.5J ET38
Cost: ~$620
Outcome: Minimal visual change, ride and fuel economy essentially unaffected.
Case 2: Balanced Enthusiast (Balanced / Flush Fit)
Profile: Wants a sportier stance without sacrificing daily usability.
Setup: F 18x8.0J ET35 / R 18x8.5J ET35
Cost: ~$3,000
Outcome: Noticeable visual upgrade, fuel economy drop within the expected range.
Case 3: Show Build (Max Aggressive)
Profile: Built primarily for shows or occasional track/show use.
Setup: F 18x8.0J ET35 / R 18x8.5J ET35
Cost: ~$5,500
Outcome: Maximum visual impact; daily comfort and fuel economy are heavily compromised, physical test fit required before production.
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
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 Ibiza Ecomotive? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Everything above is reference data. If you want wheels actually built to it, that is what ANKUSI does: we are a forged wheel factory in Guangzhou, China, IATF 16949 and ISO 9001 certified, forging on our own 10,000-ton press and producing over 120,000 wheels a year. Forging blank, CNC machining, finishing, coating and inspection all happen in the same building — nothing is subcontracted and nothing is relabelled from another manufacturer.
Every set is cut to order, so the 5x100 pattern and the 57.1mm centre bore are machined for this car specifically rather than shimmed with adaptor rings. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose.
We do not hold 5x100 wheels on a shelf — they are forged to order, which is why any offset, width and bore combination on this page is buildable rather than limited to a stock list.
In our database, 85 other vehicle entries from 11 makes use exactly the same 5x100 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.
5x100 is used by 1.9% of the vehicle pages in our English fitment guide (124 of 6,503); 69.4% of those also use a 57.1 mm center bore.
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) | 15x5.5J | ET38 | 4.75 in (121 mm) | — | — |
| Flush | 18x8J | ET35 | 5.88 in (149 mm) | +29 mm | +35 mm |
| Maximum | 18x8J | ET35 | 5.88 in (149 mm) | +29 mm | +35 mm |
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.
