My solution was to buy a second hand bonnet with a bonnet mounting kit already on.
Yes with the spare on the bonnet it does limit the view of the N/S front corner. Only have it on bonnet when need to carry two spares. Must admit I keep the second hand bonnet on with mounting kit on for normal driving as am too lazy to put original bonnet back on.
As for carrying a spare wheel on a roof rack, I am not too keen on roof racks. The maximum weight on a Defender roof is either 75 kg or 150 kg dependent on if you take the UK or South African figure. Assuming a rack weighs 20+ Kg and a tyre weighs 25 Kg you dont have much carrying capacity left on your roof rack if you go by the UK figure.
Personally I believe most people overloaded their roofracks.
