Anyone fitted alloys from an E39 BMW.

Postby Morgan1 » Mon Jan 13, 2020 8:21 pm

Hi all. Just fancy a change and have come across a cheap set of BMW alloys from an E39. BMW have the same centre bore diameter and 120 x 5 wheel nut spacing instead of 120.6 x 5 on the Jaguar. Offset is slightly different but has anyone experience or photos of BMW alloys on a xj40? The set I was looking at was 16in standard 5 series ones that look like a roulette wheel.
1992 Jaguar xj6 3.2 litre.
2016 Audi A6 S line.
2016 Ford Fiesta zetec.

I'm putting this up on behalf of Starbuck's sister. She is also an engineer.

"The difference between 5x120 and 5x120.65 doesn't sound like much. For a two ton car each set of studs is holding 500kg static weight, let alone transferring torque from accelerating and braking. The difference between 120 and 120.65 is enough to damage the threads on the studs, strain the studs, oval the holes in the hubs, and damage the tapers on the alloy wheels themselves.

Fitting wheels with the wrong PCD can also void your insurance in the case of an accident as the wheels work loose quite quickly as the nuts do not bolt up 'square' so have reduced clamping force. In short - don't do it. Buy wheels with the correct PCD."
