PCD & Bolt Pattern Guide: 4, 5, 6 & 8 Holes Explained

The #1 reason mag wheels don’t fit isn’t the size — it’s the bolt pattern, or PCD. Get this number wrong and your new mags simply won’t bolt on. This guide explains exactly what PCD is, how to measure yours, and the common bolt patterns for popular Philippine cars.

What does PCD mean?

PCD stands for Pitch Circle Diameter — the diameter of the imaginary circle that runs through the center of all your wheel’s bolt holes. It’s written as two numbers like 4×100: the first number is how many bolt holes the wheel has, and the second is that circle’s diameter in millimetres. A wheel must match both numbers to fit your hub.

Step 1: Count your holes (4, 5, 6 or 8)

Look at one of your current wheels and count the lug holes. This is the quickest way to narrow things down:

• 4 holes — common on compact cars (Toyota Wigo, Mitsubishi Mirage, older Vios).
• 5 holes — most modern sedans and crossovers (Honda Civic, City, Toyota Innova, Fortuner).
• 6 holes — many pickups and large SUVs (Hilux, Montero Sport, Isuzu D-Max).
• 8 holes — heavier trucks and some commercial vans.

Step 2: Measure the diameter

For 4, 6, or 8-hole wheels, measure centre-to-centre across two directly opposite holes. For 5-hole wheels (which have no directly opposite hole), measure from the back edge of one hole to the centre of the hole two positions away. The result, in millimetres, is your PCD diameter.

These are typical values — always confirm your exact variant before buying. Once you know your PCD, browse our mag wheels price list and we’ll verify fitment before you pay.

Why PCD matters for safety

A wheel with the wrong PCD can’t seat flush against the hub, even if you force the lug nuts on. That’s dangerous at any speed. Matching PCD (and offset) isn’t optional — it’s the difference between a safe upgrade and a serious risk.

Frequently Asked Questions

How do I find my car’s bolt pattern?

Count the lug holes and measure the circle they form, or simply send us your car’s make, model, and year and we’ll confirm your PCD for free.

What’s the most common bolt pattern in the Philippines?

5-hole patterns like 5×114.3 are the most common for modern sedans, MPVs, and crossovers, while 4×100 is common on compact cars.

Can I change my car’s bolt pattern?

Yes, using PCD adapters, but for most drivers it’s safer and cheaper to buy mags in your car’s native bolt pattern.

Does PCD affect tire size?

No — PCD is about how the wheel bolts to your car. Tire size is separate, though both must suit your vehicle.
