Every car I see with Contis on, not just Land Rover, have worn shoulders, and that includes mine.. they are dreadful! 5.0 Ltr Superchrged RRS2, Chile Red, Sideways out of junctions!
TDV8 HST Stornaway on a 08.. remapped.. now gone and replaced, was a mighty fine car..
4.2 SC First Edition when they first came out, quick car!

Speaking of tyres, I just discovered a puncture on the rear left tyre, so will have to replace it.

It is OK to put 2 new tyres on one axle, or does one have to replace all four at the same time?

And it is OK to have tyres of slightly different patterns on one axle? --
