275/55R20 KO2 or LTZ

If I could have bought a set of D4 19" rims cheaply then I would have tried them with Hankooks. 18" are still a possibility but the 20" would have to be bad to warrant the investment in rims and new brakes too.

The large 20s adversely affect the gearing at 100 kph where the revs are just a little low with these vehicles' high ratio diffs when towing a trailer, but not enough to warrant a rim change. The extra 1" body height is proving a nuisance, having to drop to the bump-stops for my wife almost every time so I may have to get side-steps. I'll have to do something to lessen the reverberation from these tyres too - the noise is currently worse than the 17" Duratracs I had on the D4.

More tyre choices in 18" although probably still enough in oversize 20".

Where are you at Graeme? I'd love to check out your car and see the Tyres.

I'm at Marrar, half an hour north of Wagga, so not just 5 mins away.

Are you contemplating going to the LR Expo at Camden? I'm considering a short visit as I have family in Camden and Narellan to see at the same time.

Edit: Most likely Saturday.

Unfortunately I'll be away in the grampians rock climbing.
I'd love to go though.

Today whilst fitting the Tow-Pro I found that there was still a half inch gap along the left side between the foam strip and the floor cover. The layer of thick carpet now glued to the underside of the foam strips seems to have closed the gap but I'll have to wait a day or 2 to discover if there's any improvement. Dynamat is yet to be fitted to the panels in the spare wheel well.

Prompted by a remark on another forum, I realise that mine's spare wheel well floor is free to resonate whereas its normally damped by the spare wheel resting on and clamped to it, as my spare tyre only sits up on the edges. Its probably also why the engine noise from passed trucks is only heard as the front of the truck slips past the rear of the RR. Changes will be made!

Did you want some ffrr 19"? I have 5 laying about

Thanks for the offer. However having gone down the path of acquiring the 20" BFGs I will be persisting with trying to tame the noise they generate. Also, unless the rims are from a MY11/12 they supposedly don't fit over the 6-pot Brembo front brakes.

It seems that I struck gold with fitting dampening material to the flat panels in and around the spare wheel well. However the front still needs attention so I'll start with a couple of areas visible under the bonnet although I suspect there will be other culprits that reverberate.
