Fitting wheels on a Triumph TR6

A Triumph TR6 (1968–1976) uses a 4x114.3 PCD and a centre bore of 70.2 mm. Any wheel must match the vehicle's PCD exactly: there is no tolerance, unless you use a PCD adapter.

PCD: 4x114.3 required. See all vehicles with 4x114.3.
Centre bore: the wheel must have a centre bore of 70.2 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 70.2 mm.
Offset: the original is ET6. Compare your future wheel with the offset calculator (your vehicle is already selected) to see how many millimetres further in or out it will sit.
Fixings: thread Ecrous - 7/16 - 20 U, tightened to 75 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.

Frequently asked questions

What is the PCD of a Triumph TR6?

A Triumph TR6 (1968–1976) has a PCD of 4x114.3: 4 studs or bolts spaced around a circle 114.3 mm in diameter.

Does a Triumph TR6 need a hub centric ring?

The centre bore (hub diameter) of a Triumph TR6 is 70.2 mm. A wheel with a larger centre bore is fitted with a hub centric ring that brings it down to the hub diameter. A wheel with a smaller centre bore cannot be fitted.

What offset (ET) for a Triumph TR6?

The recorded original offset is ET6. A lower ET pushes the wheel outwards, a higher ET pulls it inwards: check wheel well and caliper clearance before making any change.

What tightening torque for the wheels of a Triumph TR6?

The specified tightening torque is 75 Nm for Ecrous - 7/16 - 20 U fixings. Tighten in a criss-cross pattern with a torque wrench and check the tightness again after about fifty kilometres.
