TVR Tuscan wheel specs by year and trim
| Year | Model / trim | Bolt pattern | Center bore | OE wheel |
|---|---|---|---|---|
| 2006 | TVR Tuscan | 5x114.3 | 68.1 mm | 18x8J ET35 |

Factory wheel sizes on the TVR Tuscan
Across the 2 TVR Tuscan trims with a documented factory wheel, the OE diameter is 18 inch, width 8J and offset ET35. A forged wheel that keeps the 5x114.3 bolt pattern and the 68.1 mm hub bore and stays inside that offset range bolts on without spacers or hub rings. Going one inch up in diameter with a lower-profile tyre keeps the rolling circumference inside the usual 1.5% tolerance; every extra 0.5J of width moves the outer lip about 6 mm outward at the same offset, and each 5 mm less offset moves the whole wheel 5 mm outward.

Offset and Backspacing: Factory Wheel vs Options
Backspacing ≈ width/2 + ET/25.4 + 0.5 in. "Inward" means closer to the suspension; "outward" means closer to the fender lip.
| Setup | Size | ET | Backspacing | Inward vs OE | Outward vs OE |
|---|---|---|---|---|---|
| Factory (OE) | 18x8J | ET35 | 5.88 in (149 mm) | — | — |
| Flush | 18x8.5J | ET30 | 5.93 in (151 mm) | +1 mm | +11 mm |
| Maximum | 19x9J | ET25 | 5.98 in (152 mm) | +3 mm | +23 mm |
Hub-Centric Rings for a 68.1 mm Center Bore
A wheel with a center bore larger than 68.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 70.1 mm | 70.1 → 68.1 mm |
| 70.5 mm | 70.5 → 68.1 mm |
| 71.6 mm | 71.6 → 68.1 mm |
| 72.6 mm | 72.6 → 68.1 mm |
| 73.1 mm | 73.1 → 68.1 mm |
ANKUSI forged wheels are bored to exactly 68.1 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a TVR Tuscan?
The TVR Tuscan uses a 5x114.3 bolt pattern with a 68.1mm center bore across every Tuscan variant in our database (2 guides, 2006).
What is the TVR Tuscan center bore?
The hub-centric center bore is 68.1 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all TVR Tuscan years share the same wheel fitment?
The bolt pattern and center bore are the same across the years we cover, but OE wheel width and offset differ by trim, so check the exact model line before choosing an aftermarket size.
Which forged wheels fit the TVR Tuscan?
Any wheel drilled 5x114.3 with a 68.1mm hub bore in the offset range shown on the model guide. ANKUSI forges wheels to order for this exact specification, in 14–24 inch diameters, so no adapters or hub rings are needed.
