spare tyre on puma bonnet?

Theres a old thread of mine from a few years back on this subject, the French fire service use a spare bonnet carrier on their pre 07 Defenders.

The one in the picture on this thread is made by a company that we have recently become a distribution agent here in Australia. We will be offering a number of products from their range, we have not yet decided on this product however.

As for the issue of ADR, the issue only become relevant when a percentage of the drivers forward vision becomes obscured.

If you were to put a skinny tyre on there, say a XZL you would may well get away with it, anything larger and you would be illegal.

Page 12 and 13 will help you...

A spare wheel on the bonnet qualifies as a "bonnet protrusion" ;)

Hence my original comment....

4.1 BONNET SCOOPS AND PROJECTIONS
Modifications to the bonnet of a vehicle must take into account the possibility that a pedestrian
or cyclist might strike the scoop or bonnet projection in a collision. The top surface of a scoop
must not be more rigid than the original bonnet.
For vehicles manufactured prior to 1 July 1988, there are no specific design rule requirements
relating to bonnet scoops. However any such fixture that is a dangerous protrusion or obstructs
the driver’s forward view of the road, is prohibited by both the ADRs and AVSR. For vehicles
manufactured on or after 1 July 1988, ADR 42/... prohibits external or internal protrusions that
are not technically essential and are likely to increase the risk of bodily injury to any person.
Rigid engine-mounted components that are likely to increase injuries to a pedestrian in a
collision must not project through and above the vehicle’s original bonnet profile, unless
protected with a cover mounted to the bonnet.
Bonnet-mounted scoops must meet the following requirements:
 When a 165mm diameter sphere is placed on the bonnet in front of the scoop (or
bonnet projection) and rolled rearwards until it touches the scoop, no point of contact
between the sphere and the scoop must lie above a horizontal plane passing through
the centre of the sphere

Given all the clever dicks driving around with lights on the top rail of their bull bars I would reckon a skinny on a land rover bonnet would be viewed more as a standard accessory item than a protrusion/obstruction to forward vision. When I have driven with one on the bonnet of "the count" it has been less obstruction to forward vision than the bull bar actually was. And you know what, I just love the look too! It really shouts Landy to me.

In saying that, I would probably only leave one on there when I want to take 2 spares remote off-roading or long distance touring.

Oh yeah, the difficulty lifting the extra weight on the bonnet is only relevant for the vertically challenged and elderly amongst us. Its not excessive with a skinny steely on and I am no muscle bound hulk hogan.

Also Illegal if it protrudes above the bonnet line ;)

Not by any investigator if you hit / maim / kill a pedestrian. :eek:

Like all laws, its only illegal until you get caught...

But in the case above, if it goes pear shaped (wheel kills a pedestrian, or wheel rips off bonnet in collision and hurts or kills someone) you are royally ****ed... (To quote Mrs Brown)

I have a R750x16 on the bonnet and yes it does impair vision slightly, but so would a lowering of the seat and that is not illegal. Pic attached.

Anyway mine is an 85 model so its legal.

I am vertically and aged challenged so to open the bonnet I have to stand inside the bull bar, and that gets it up so to speak.

Actually Jim,

Lowering the seat and/or mounts is illegal - unless they are tested for compliance and certified.

Without setting up the correct test would be hard to tell (you appear to have taken photo from dash not your eye level / position)

Pedestrian Vs Land Rover (wheel on bonnet or no wheel on bonnet) and they are royally ****ed... (To quote Mr Tombie!) the rest is semantics by over educated, under lifed, beuaracratic, tosser, bleeding heart, do gooders.

If in doubt, tyr and get a local engineer to approve one of the available mounts. It would be really cool to see a few more getting around with that traditional look!

Tombie,
You are right, the photo is not at eye level it is from just above the steering wheel. At eye level there is less intrusion to the drivers view by the wheel.

Re safety, I suspect a pedestrian heading toward the windscreen would rather the impact of a curved compressible tyre than a flat hard object, but I will leave that to the experts.

What I can tell you is I saw a quarter brick sized rock heading for the windscreen, which made a fantastic change of direction when it hit the tyre.
