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 TVR Chimaera ships from the factory on a 5x114.3 bolt pattern with a 68.1mm center bore and a F 15x7J ET35 / R 16x7.5J ET35 wheel. Our flush reference for the TVR Chimaera is F 16x7.5J ET30 / R 16x8.5J ET25.; our maximum aggressive reference is F 17x8J ET25 / R 17x9J ET20. — beyond that, expect clearance issues against the fender liner without further modification.
TVR Chimaera OE Wheel Specs
The TVR Chimaera ships from the factory on 5x114.3 bolt pattern wheels with a 68.1mm center bore. The stock wheel size is F 15x7J ET35 / R 16x7.5J ET35, 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 TVR Chimaera owners run F 16x7.5J ET30 / R 16x8.5J ET25. 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 17x8J ET25 / R 17x9J ET20. Gaz Gold pro coilovers; 16/17-inch staggered wheels; Tarox or AP Racing brake kit; Avon ZV7 tires. Note: Grand touring roadster built on the Griffith backbone frame; check chassis outriggers for corrosion. Clearance should be verified before ordering, especially on lowered cars.
