I've had the 285/70R17s on for several years, no tailgate rattle, fits with no issues.
I did have a clunk from the back, but I tracked that down to the PO having had an ARB 2" lift... They had fitted a drop bracket to the rear trackbar & one of the bolts was catching on the rear swaybar arm! Had warn a quarter of the way through it! Also the shocks were over 100,000km at that point & one of the rears was a bit dodgy. Replaced & no more knocking.
