Forza R1

Choose your car and we'll tell you whether Forzza Forza R1 is listed in our sample fitment data — before we ever confirm an order.

Make-level sample guidance for this product: Audi, BMW, Mercedes-Benz, Volkswagen. Model-level checks below are the sample fitment data.

Fitment shown is sample data. We always check geometry and compatibility against your exact vehicle before confirming any order — reducing the chance of incorrect orders and returns.

The numbers on a wheel tell you whether it can physically go on your car. Here's what they mean:

• Diameter (18") — Rim size in inches. The tyre's rim diameter must match the wheel diameter exactly.
• Width (8.5J) — Rim width in inches (the J is the bead profile). Width affects which tyre sizes are approved for the rim and how the wheel sits in the arch.
• PCD (5x112) — Pitch circle diameter — the bolt-hole pattern. 5x112 means five bolts on a 112 mm circle. The pattern must match your hub or the wheel cannot be fitted.
• Offset / ET (ET45) — The offset (ET) is the distance in mm from the wheel's centreline to the hub mounting face. It controls how far the wheel sits in or out of the arch.
• Centre bore & spigot rings — The wheel's centre bore should match your hub. If the bore is larger, spigot/centric rings adapt it precisely — we confirm this (and rings are available in Accessories) before your order.
• TPMS / valves — Cars with factory tyre-pressure monitoring (TPMS) need compatible valves or sensors when wheels are changed. We check this against your exact vehicle before confirming.
• Bolts — This sample wheel includes its bolts (20x conical black bolts included) — we still confirm the bolt seat, length and thread against your exact vehicle before confirming.

Every order is checked against your exact vehicle (geometry, PCD, offset, centre bore and brake clearance) before we confirm it — this guide is educational only and not a fitment guarantee.
