Early Defender Deep Dish Wheels on a PUMA...?

[BilboBoggles]

Hi All,

Just picked up a cheap set of wheels and tyes for my defender (the PUMA this time). They are the original Deep Dish mag wheel from a 2000 year defender. Iv'e checked the load rating stamped on them and they are 925kg which I think confirms they are defender fitment.

Can these be fitted to a PUMA? Ive seen a note on the land rover website when I searched using the part number that these types of wheels are Pre07MY only. Why would that be? As far as I can see the axles have not changed... Could it just be a load rating issue?

Do these wheels require a different type of Alloy wheel nuts? I have boost Alloys fitted, and I wanted to use this second set to run KM2's for offroading. Can I use the same wheel nuts? OR are the deep dish wheel nuts unique.

Any information appreciated!

thanks

They're identical to the boosts in every way, except they have a different appearance, but do check the load rating, AFAIK boosts are also 925kg though.

Outside that you need an engineering approval. http://www.rta.nsw.gov.au/registration/downloads/vsi/vsi09_rev4.pdf

These wheels were a factory fit to a 2000 Defender. They are pre boost, but as far as I can tell have a 33mm offset which I think is the same as the boost. I'm curious as to what is different in the PUMA that caused Landrover to state they do not fit post MY07 models...

You will notice that all the later Land Rovers with ABS have positive offset rims. The reason is that having a negative scrub radius between the kingpin inclination and the wheel centreline reduces torque steer and increases stability in the event of brake failure.

Hmm, the NSW RTA used to allow up to 50mm increase in track width for beam axle 4WD's.

I wonder when they dropped that ?

Aren't they the same offset?? (33mm) after all, Td5 110's had ABS, and those 'deep dish' alloys were standard fitment on 1998 SE Discoverys, some of which had ABS (mine didn't, but had those rims). And Diana didn't you have a set on your Range Rover?

Correct me if I'm wrong, but don't all those vehicles have a negative 33mm offset?

Out of curiosity is the car in question a 90, 110 or 130? 130's actually have a wider offset as stock, however the heavy duty 'Wolf' rims are an option for 110's... I'd love to see a tyre placard and see what they list as the wheel options.

Yep, they all have 33mm offset

The 130 rims are 20.6mm offset, so add 25mm to the track width and AFAIK you can get the 110 optioned up with the HD pack too, which I'm guessing includes the rims ?

WillI still have a set on my Range Rover (in fact I have 14 of them), but you will also realise that they were the first LR alloys that were fitted to both the Disco 1 and the Defender Xtreme.

My RRc also came with alloys OEM, but when I changed the colour I didn't like the original alloys.

AFAIK that puts them within the owner certified modification limits.

what width are the alloys....when calcing the offset of the wolf/130 rims are you considering the difference in width of the alloys also?

remember track width is measure from Center of tyre to Center of tyre..

remember track width is measure from Center of tyre to Center of tyre..Now there's a point, 130 rims 6.5" alloys 7", however the offset is still measured to the tyre centre.

If you were measuring to the outside of the tyres, you would only be widening the outside to outside as + 12.1mm

It's going on a 110, was hoping to use them on the PUMA - but if there is an issue with fitment there - then I can use them on the Td5 110, and put the td5110's boost alloys as a spare set for the PUMA.

I think I've found the answer

TD5 Rear Axle load limit is 1750kg, with an option to go to 1850kg with a heavy duty pack.

PUMA Rear axle load limit is 1940kg. So 925kg wheel rating is just a little too light.

So I wonder if they have changed the later model Boost wheels to be rated a little more than 925kg...
