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 sedan's wheel spec is a balance point the factory tuned between ride comfort, steering feel, and everyday durability. Forging lets us hold that same structural margin while cutting rotational mass, which is where most of the real-world benefit — quicker steering response, marginally better ride — actually comes from.

The Maserati GranTurismo Folgore ships from the factory on a 5x110 bolt pattern with a 65.1mm center bore and a F 20x8.5J ET35 / R 21x10.5J ET40 wheel. Our flush reference for the Maserati GranTurismo Folgore is F 20x9.5J ET25 / R 21x11J ET30.; our maximum aggressive reference is F 21x10J ET20 / R 22x11.5J ET25. — beyond that, expect clearance issues against the fender liner without further modification.

Maserati GranTurismo Folgore OE Wheel Specs

The Maserati GranTurismo Folgore ships from the factory on 5x110 bolt pattern wheels with a 65.1mm center bore. The stock wheel size is F 20x8.5J ET35 / R 21x10.5J ET40, offering a balanced ride that suits most owners without any rubbing or clearance concerns.

Why the factory spec works for most owners:

  • Balances ride comfort with steering response and highway efficiency.
  • Wide tire and wheel availability at the factory diameter keeps replacement costs low.
  • Lower unsprung weight than larger aftermarket wheels helps ride quality and acceleration.
  • Guaranteed clearance against brake calipers and suspension components.

Flush Fitment

For a flush look without any body modification, most Maserati GranTurismo Folgore owners run F 20x9.5J ET25 / R 21x11J ET30. This setup tucks the wheel face closer to the fender lip while staying within safe load and clearance limits.

Maximum Aggressive Fitment

Owners chasing a more aggressive stance push to F 21x10J ET20 / R 22x11.5J ET25. Chassis: Lowering springs. Wheels: Staggered diameters, EV load rating required. Brakes: High-disk face. Tires: 265/30 R20 F, 295/25 R21 R. Clearance should be verified before ordering, especially on lowered cars.

Decision Guide

1. What is this car mainly used for? Daily driving favors Tier A or B; weekend/show use favors Tier D or E.
2. What is your budget? Tiers A-B keep cost low; Tiers D-E cost significantly more in wheels, tires, and possible suspension work.
3. Is fuel economy and ride comfort a priority? If yes, stay at Tier A or B; heavier, wider wheels at Tier D-E reduce efficiency and comfort.
4. Still unsure? Tier C (Balanced / Flush Fit) is the safe default for most Maserati GranTurismo Folgore owners.

Offset & Backspacing Reference

Backspacing is calculated as: wheel width (in) / 2 + offset (mm) / 25.4 + 0.5.

  • OE 20x8.5J ET35: backspacing ≈ 6.13"
  • Flush 20x9.5J ET25: backspacing ≈ 6.23"
  • Max 21x10J ET20: backspacing ≈ 6.29"

Frequently Asked Questions

What bolt pattern (PCD) does the Maserati GranTurismo Folgore use?
The 2023 Maserati GranTurismo Folgore uses a 5x110 bolt pattern.
How many lug bolts does the Maserati GranTurismo Folgore use?
The Maserati GranTurismo Folgore uses a 5-lug bolt pattern (5x110), so you need a 5-lug forged wheel to bolt straight on.
What does a flush wheel fitment look like on the Maserati GranTurismo Folgore?
For a flush look with minimal to no rubbing, we recommend F 20x9.5J ET25 / R 21x11J ET30 as a starting point on a stock or mildly lowered Maserati GranTurismo Folgore.
Do I need wheel spacers for my Maserati GranTurismo Folgore?
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 Maserati GranTurismo Folgore?
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 6.23" backspacing up front and 7.18" in the rear.
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 Maserati GranTurismo Folgore?
Yes — the Maserati GranTurismo Folgore's factory and our recommended flush/max fitments already use staggered sizing (different width front and rear), and ANKUSI can forge matching staggered sets to your target offsets.
