Huh?

No, no problem.

You will get conflicting advice as to which axle to put the new tyres on - I'd put the new ones on the back and the part-worn ones on the front as generally understeer is a better characteristic than oversteer in a 2-ton 4x4!

Be aware also that at least one member experienced a vibration as a result of an over-enthusiastic Haldex self-test under similar circumstances (the different rolling radii of new vs worn tyres was causing wind-up), but if you do get this there's a software update available which fixes it.

I think sometimes the difference in front rolling diameter and rear can put excessive strain on the 4wd unit/haldex .I could be wrong but was hoping someone could clarify,it used to knack the old freelander centre coupling

The FL2 system is more sophisticated and doesn't suffer from the same issues as the FL1. Most of the time the FL2 is running in (more or less) 2wd anyway, and when the Haldex is engaged (when moving off from rest, in special programs, or when wheel slip is detected) it has various protection mechanisms built in which prevent damage.

The only possible risk is to the nose bearing on the rear diff - it has been sugested that drivetrain stress is a contributary factor in premature failures of this bearing, but there's no hard evidence of this and it seems that these bearings are simply fragile.

News on rear is correct as expressed above but not as critical on a vehicle such as the FL2 with safety features fitted. I would strongly advise same brand/type of tyre as those remaining. AWD are designed to handle indifferent wheel diameters created by wear but mixing different brands/types and wear levels can fall outside engineered tolerances. MY15

My last FL2 was a fleet car and they were in charge of the maintenance, so when it came to tyre renewal time, the fronts were down to 2mm but the rears still had 3.5mm, I was expecting them to say fit new fronts and leave the rears as they still had a few thousand on them on their rejection limit, but no I was surprised they said, no on FL2 we renew the whole lot at the same time prevent any possible drive problems later, so I guess if they do it then they must have experience its worthwhile as in the past nothing was changed until it had to be?.

new tyres would be same make/type. seems strange ,I would rather have a tail end slide than understeer hence me thinking best tread up front………...

There is variation between brands of the same size!
"Rear end slide"! Your vehicle is equipped with DSC is it not! Do you turn it off every time you get into the car? MY15
