Hello Geoff,
As always, when it comes to finding out about essential information, and especially that which has legal implications, do not trust third party web sites such as this. Even with the best of intentions, sites such as this and the those that claim to have full details can get the information wrong.
As nose and loading weights have legal implications, you are required to get it right, as ignorance of the law or limits is not a defence if a prosecution is brought against you.
Always get the information either form your official handbook supplied with the car, or check with the dealer or manufacturer.
