275/55R20 KO2 or LTZ

The reverberation cause has been resolved. The set of 4 brake pipes attached to the ABS modulator has 2 spacer clips, 1 not far from the modulator and the other out of sight down inside the cavity. The clip in the cavity was only attached to 1 pipe which allowed the pipes to rub together, which along with the very flexible modulator mounts allowed the modulator to rattle the pipes.

I still have to find the source of the front suspension rattle which occurs when slowly moving forwards or backwards over bumps and still can be heard at speed on gravel or our local sealed roads. The sub-frame bushes in the rear/upper arm obviously have been hitting their internal bump-stops but as the rattle also occurs in reverse, I suspect the bush is not the culprit.

Hello Graeme. How are those tyres holding up? I just blew out a front tyre tonight along the M5 when I hit a random object with my front right tyre. So it's time for me to buy a new set of tyres now. The rears are both on they last legs. Im thinking BFG AT KO2 or General Grabbers if they make the right size.

The KO2s are going fine, albeit with a little more noise on some surfaces than I'd like. Traction is never a problem either on wet bitumen at speed or sneaking through sometimes deep muddy slops trying to minimise road damage to lessen the risk of getting bogged on later passes.

Thanks mate.
I also like the look and specs of the Yokohama Geolander G012 in the same size.

I had and liked the Geolander G012 in 17" on the D4 and having discovered them in this size with LI 117 since getting the BFGs and wanting less noise, I'm leaning towards the Geos for the next set. One of the reasons for fitting the e-diff is to remove some of the reliance on more open tread patterns. I really like the BFG performance in sloppy stuff but not the noise. I have enough problems hearing without adding to the not-so-background noise. A draw-back with the Geos is their narrower tread exposing the sidewalls to rocks, although I haven't seen a 275/55R20.

Hi Grant.
I am looking for some new rubber for my '12 RRS and do about 90% on road (suburban driving, and highway towing a 2 t caravan. Don't want true off-road like the KO2 so interested in your comments on the ATRs.
So in your opinion the better choice is the ATR's?

Thanks
Graeme

275/55R20 are too big for pre-MY14 RRS regardless of brand.

Graeme, your FFRR must be much more noisy than the D4! I can barely hear anything different with my K02's and there is no annoying noise, anymore than I had with D697's or Continental Cross Contacts before them. Mine even have a couple of pretty large rock chips from the Bungle Bungles track and Birdsville Track, which haven't made any difference to the noise.


I find the handling better than any other tyre I've used on the D4 and no noticeable increase in harshness, so apart from the high cost, I am very pleased.

The RRV's noise apart from these tyres is virtually non-existent but my hearing could be unusually sensitive to resonating tyre noises. I also suspect that although these vehicles are very will insulated from drive-by noises from other vehicles, tyre on road noise hasn't been addressed sufficiently because the vehicles aren't expected to be fitted with aggressive tyres.

Hi Graeme, yes is my short answer. I have found the ATR's to be great in all conditions and I really like them! I would defer to other Graeme in regards to RRS fitment though as I am unsure about this.
