they told me the same thing, 50mm increase in tyre diameter is the maximum permitted, no exceptions, did see someone was going to try and argue that land rovers all have similar chassis and running gear and get plus 50mm on the defender standard size tyre but that was regarding a classic and I'm not sure he was going to get very far!
Does anyone have the size of an 18" fitted to a P38?
Since they were a factory option surely the 50mm increase can be based on them and not on the 16" wheels
Steve
They are also 29" wheels. I checked hoping that my 32" were legal... But not.
So I just run low pressure ha ha.
50mm increase is based on the Outside Diameter (OD) of the tyre, not the rim.Quote:

Hi
chatting with Benji from Rampt customs yesterday he mentioned the regulations were related to diff and brakes.
Eg: Certain Nissans came with bigger tyres and if you used their diffs on another vehicle apparently it is legal
Not much use to us P38 owners though I don't think
Steve
Actually this may help us because the P38 and the Defender share the same "Rover" type diff and the Defender came from the factory with 32" wheels
So it may be possible to argue that the diff supports larger size wheels.
Getting way out of my zone of knowledge here though !
Steve
To justify a Defender diff under a P38 (to the law) would require a mod plate... But it sure does open up the choice of wheels and gives those floating axles ;-)

I sometimes wonder if people use the term diff when the mean the entire axle assemblyQuote:

That's my bad - in North QLD we have issues saying what we really mean ;-)
