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
A big saloon lives or dies on ride quality, and the wheel is the first thing that ruins it. Going wider and lower without watching load rating and offset trades away exactly the composure you paid for. Forging lets you add diameter and width while keeping rotating mass close to the factory figure.
We publish the factory specification for the Buick Roadmaster 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.
Buick Roadmaster OE Wheel Specs
The 1995 Buick Roadmaster (Performance Sedan) uses a 5x127 bolt pattern with a 78.1mm center bore. Factory wheels are 15x7J 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 Buick Roadmaster (1995) we drill the 5x127 pattern and cut the centre bore to 78.1mm 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.
Need a wheel for this car now? Contact ANKUSI with your target diameter, width and offset and our engineers will confirm the correct forged spec against your brake package before anything is cut. You can also use our Offset & Backspacing Calculator to work through the numbers yourself.
Frequently Asked Questions
What bolt pattern (PCD) does the Buick Roadmaster use?
The 1995 Buick Roadmaster uses a 5x127 bolt pattern.
How many lug bolts does the Buick Roadmaster use?
The Buick Roadmaster uses a 5-lug bolt pattern (5x127), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Buick Roadmaster?
The Buick Roadmaster's center bore is 78.1mm. 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 Buick Roadmaster?
Factory wheels on the Buick Roadmaster are 15x7J F/R.
Do I need wheel spacers for my Buick Roadmaster?
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 Buick Roadmaster?
The Buick Roadmaster 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.
