Many thanks for your advice. Following suggestions from others I had already
checked that the landing gear frame was symmetrically installed and that the
landing gear swinging arm was central in the tunnel. However, I have this
morning carried out the further check youi suggest and this has confirmed that
the
tyre aligns exactly with the centreline.

I can see the attractions of a thinner tyre. It would certainly give much
better clearance on the brake master cylinder and the brake caliper. But I am a
bit worried about the 15mm bigger diameter. There is already very little
clearance between the tyre and the flap push rod, and with a bigger diameter
tyre
this could become a problem.
