Any idea why? My fronts always wear faster (suspension is mechanically sound and aligned). I've observed no handling issues with the rotation.

Again my LR Mx schedule says to this every 15K/12 months:

"Install road wheels to opposite side of the vehicle – except
uni-directional tires which install on same side"

 

I'm looking at the 08 LR2 Maint Schedule and it says (page 27):

"Remove all road wheels before inspecting brake components".
"Refit wheels to opposite sides of the same axle, unless vehicle is fitted with unidirectional tires".

These instructions follow the brake inspection every 15Kmiles/12 months, as you said. It doesn't scream out "rotate tires" like I was looking for, but that's what it describes!

 

My tires are unidirectional. They all turn the same way when I am moving.

 

Any idea if our suspension is the same as the Volvo? At some point Volvo ends and LR begins. I'm pretty sure it's not a common chassis... ie it's not a Volvo with a LR badge and trim, it's a LR with a Volvo power train.

 

What LR? It's either Volvo or Ford. The platform is Ford's EUCD, also used modified form in the Jaguar X.

 

I am going to make a leap here.............I am guessing it's related to the ptu/haldex/rear diff longevity. I am assuming that each tire wears a certain way on the vehicle and since the rear diff and even the haldex have issues with failure, once the tires are worn in, they place less stress on the "all wheel" drive system (when it's engaged or engaging) hence extending the life of each of these components.
