I'm sure the same would apply to OE tyres being used on inappropriate terrain.

You're overthinking it, just get out there and have a go. If you're on road biased tyres drive accordingly. You'll be fine. If you're taking it easy what's the worst that can happen? A scratch on the rims I reckon. Change the rims to 20's and put on the tyres you want or make the best of th19's. The only area you would have issue with JLR on is if you started to complain about vibration or noise etc...they wont do anything until you put OEM tyre/rims back on.

Am i right in thinking that's more blaming the tyres for the symptoms?

If you can reproduce the symptoms on a set of road tyres then why shouldn't the warranty be honoured?

If JLR are claiming that the use of a different tyre to what the vehicle was shipped with has caused damage to the suspension or steering then I'm more than a little worried...

Since LRA gave geckoPG an Experience voucher they must have thought the vehicle was capable of going off road with the standard tyres.

It begs the question that when it comes to changing any tyres, would they need to be LR approved ones? I would doubt that very much unless LRA can come up with a list? Also, on 235/65R19 tyres the sidewall would absorb more bumps than a lower sidewall tyre on 20" rims - ie less vibrations to the suspension components rather than more.

And should LRA refuse a warranty claim on the basis of the tyre profile, shouldn't they have to prove that? Innocent until proven guilty? And if they say it is because you took it off road then just say the surface was as "reasonably smooth off road" as the roads we went on with the LRA provided Land Rover Experience voucher.

That seems to be the angle that JLR are coming from. They won't condone the use of any tyre other that the ones they have approved eg the 255/55R20 on a 20" rims. Anything else will void the warranty.

"...I have been advised that Land Rover Australia, under any circumstance, will not make any exceptions or authorise tyres that have not been certified by Land Rover UK Engineering. While you are at liberty to fit after market items that are suitable for the particular usage you seek (as long as it is done in accordance with the relevant state laws including speed and load ratings) please acknowledge that any subsequent issues caused by such items will not be covered by your warranty." ....quoted from an email received from JLR Aust.

Apparently the 255/55R19 are approved in the UK but this approval has not transferred to Australia....."The OE tyres are fitted such that the vehicle meets stringent government regulations covering emissions plus are rated for fuel consumption, wet grip and noise." Quoted from another email from JLR.
Can Australia's tyre regulations be any more stringent than the European regulations that the UK has to follow??

That seems like a fairly standard statement, but they (should) have to prove that the damage to said part was caused by the 'aftermarket' tyres. Which I don't know how you would do that

Gents,

I've read through this thread and can see some comment re what's allowed and what's not but some of this reads as opinion only (no offense intended). Can anyone point me in the direction of the facts/rules re what I can fit to the D5 without running the risk of voiding warranty or insurance please?

I've got 20" OEM rims on the D5 and I want to fit some AT tyres. But.........I can't find any tyres that align with the sizes stated on the plate on the car.

Pirelli do a Scorpion ATR in P275/55R20 111S
Pirelli do an all terrain plus 275/55R20 113T
Goodyear do a Wrangler All Terrain Adventure 275/65R20 and a 265/50R20
BFG do a KO2 in a 275/55R20 115S

None of which match the plate!

Attachment 144589

You could try a General Grabber AT3 in 255/55 R20. No idea how good they are, though. If you get them, let us know [bigsmile1]

Duratracs are listed on the Goodyear AU site in 255/55R20 but are quite an aggressive AT.

Not that I can follow this table. Apparently it the latest draft....I believe the authorities have buckled and will allow 25mm lift from tyre so 50mm diameter increase.
