Odd rotation bug in models

[Macser_old 0]

I've noticed some odd things happening to the wheels in my

addons recently.Specifically a motorcycle and a four wheeled vehicle.

The wheels definately aren't rotating around

their center of geometry.

I thought at first it might be a texture alignment problem.So I

tried it with the textures removed.But it's still there.And clearly

visible in relation to the rest of the model.Looks awful!

And all wheels are off centre by exactly the same amount.

I have done similar models without incident.But for the

life of me I can't figure this out.

I've also done a lot of searching on the forums.Where I found

a thread relating to wobbling in tank wheels.But to the best of

my knowledge,that's more a "feature" than a bug.

Has anybody else come across this?

*Edit

I have cured the problem with my existing models.

But it meant having to delete the original wheels,

then rebuild them from scratch.

Copying and pasting from a template model for

the wheel may have been the source of the problem.

Not a great solution,but it got me going again.

Unfortunately it may continue to happen.
