Hello,
hopefully end of the year i will get my first Range Rover. I ordered the P510e and would like to equip it with 23-inch wheels.
Any idea why the 23 inch wheels for the Range Rover Sport P510e available, but not for the L460?

I agree, that is strange! They both have the same Gross Vehicle Weight at 3450kg.

The Scorpion Zero in 285/40x23 is rated 111Y, meaning 1090kg/tyre load and 300km/h max speed. I.e - can handle 2180kg on rear axel fully loaded. So my guess is that the RRS has slightly different load distribution estimated front/rear than the RR, for instance:

RR - load distribution at max weight:
Front: 1260kg
Rear: 2190kg

RRS - load distribution at max weight:
Front: 1270kg (or more)
Rear: 2180 kg (or less)

In such a case, the RRS would be approved with the 23" wheels, but not the RR. I can't see anything else that would limit LR from offering the 23" wheels on the L460 PHEV.

I spoke with my dealer about this earlier in the week, asking him to find out why 23" cannot be fitted to the PHEV.

I've been told the following:

"I spoke with our Workshop Controller regarding the alloys and he said that if you put the 23" Alloys on, it could cause electrical problems with the car. He said that the roll resistance is different, so the car will pick it up and could create electrical faults"

Does this sound plausible?

Personally I don't think such an explanation is plausible. Why would the RRS MY23 PHEV work perfectly fine with 23" wheels, and not the L460 PHEV? They are build on the exact same MLA platform.
I think the cause is related to max load limitations and small difference in how the load is distributed front/rear between these two models. If Pirelli can upgrade their 23" tires to 114 rating, the RR should be able to be delivered with 23" wheels.

I agree, it doesn't really make sense Erik - I think it's going to be one of those questions which will only be answered for sure by testing.

First post here, been following this thread and now have a P440e and VERY keen to put the 23s on it.

Has anyone gone and done this yet?

Ah fantastic! Good work!

Do you have any pics?

Which wheels did you go for and which tires?

One final thing, how many miles have you done and what’s the ride like?

I have covered 1200 miles and IMHO there is not a huge difference with the 21 inch the car came with.

The only time you'll need the 114 rating is if you fill the car with 5 adults (75kg each) + 340kg luggage and drive full throttle 242km/h on the German Autobahn... So I think the 23" wheels with the 111 load rating will be safe to use for all practical purposes and trips.


In the UK the tyre/wheel load rating must be sufficient for the maximum plated weight & theoretical top speed of the vehicle.
It makes no difference if you only drive with no passengers/luggage/load & never exceed the UK speed limits.

Just not worth the risk, for a number of reasons such as insurance issues in the event of a claim or MOT failure as a couple of examples.

Everyday motoring accidents won't matter to an insurance company. Right up until there's a death! Even if that death was not your fault... At this point, they will go over every car with a fine-toothed comb, looking for any reason to wash their hands of the claim... Rolling Eyes Whistle

The prospect of that is quite frightening Craig and it's a good point.

We all like to think it could never happen to us, but if it does, they'll be no turning back the clock. If a death were to occur with incorrect wheels on a car, it could lead to a very expensive legal battle, or payout by the driver if the insurers refused to provide cover in light of the modification.

Potentially, if there was a death, it could even lead to a prison sentence, especially if it could be proven that the death was linked to the different wheels, or a reduction in the cars ability to brake effectively. Of course it's all a bit unlikely, but if it does happen, you could be looking at doing Porridge, or worse, Shawshank Redemption!

Thanks for the further feedback everyone.

I get the implications and it truly is a scary thought IF you decide not to inform your insurer of the change, but if you inform your insurer of the new wheels and pay accordingly, I don’t see that argument standing up.

Take this as an example. I mod my Range Rover with a performance exhaust. JLR probably say don’t do this as it affects warranty, performance etc. However, if I inform the insurer and they still wish to insure me, then they have accepted the liability surely?

Any thoughts welcome!
