I hope so too, though with only the base model D5 and maybe a few G wagons running these tyres ex factory, I'm not holding my breath for a large selection any time soon. Much less in AT :-(
Pity, because 255/60 would look pretty sweet on the D4 I reckon...
The Pirelli All Terrain Plus (ATR replacement) is to be produced in 255/60R19 XL 113V. No availability info yet but at least it has a Pirelli stock number. I want to try this tyre on my L322.
