Thread: 20" rim D4 on Border Track, SA

Take your time on the border track - no need to race along - plenty to look at...

Pick your lines and you should be fine.

It's a great drive.

The GOE inflation kit is a good idea just to have regardless... (Thanks for reminding me)

Watched an episode of Top Gear where Captain Slow put a full fat RR through the wilds of Canada over rocks water and sand on big rims with standard road tyres against a large Army 6x6 , went places I would not go and did not seem to have a problem . As said earlier take your time .
I Think its up to the driver how good things go or don't go .

Carrying a 2nd spare largely depends on how remote you go and your appetite for the consequences of getting a second flat.
I take a second spare wheel with tyre fitted for longer and/or more remote trips.
Other people take a second spare tyre only or even just a plug/patch kit.
Tyre-only is less weight and easier to pack but requires you to be able to fit it to a wheel yourself or be within striking distance of somewhere that can.
For me, the weight penalty is acceptable for the convenience of simply replacing a 2nd flat and continuing to somewhere that can repair. I also carry a tyre plug kit.
In my view this significantly reduces the risk of being unable to continue a trip due to 2 x unrepairable flats (eg sidewall slash), which is arguably a low risk anyway.

I agree with Tombie re GOE inflation kit and carry the small kit that is only fitted if you have an air leak problem:

Got back from border track over the weekend, but car had to be towed back to Melbourne due to suspension fault. The car was limited to maximum speed of 50km, partly due to tyre issue. Today, I picked up the car and heard the suspension vibration and informed the dealer, they recon it might be caused by damaged compressor. There were few sand dunes that I had to push harder to get it past, the service told me that could cost me around $1900 without further checking by mechanic. Any suggestions? The dealer will definitely claim it was from off-road damage and will not covered by warranty. It seems me that clearance was an issue and 20" rim with low profile tyre doesn't help as well. Even though I had been very careful driving and still had the cooper types damaged half hour before we exited from The track.

Sounds like the cost of replacing the compressor. If your vehicle is still under warranty it would be hard for them to argue the compressor failing is due to off road use (assuming its not physically damaged).

I've got the same tyres, would be interested to hear more details of your experience - pressures, speeds, terrains, comparison to others you were travelling with?

The 50 kph is a warning only. If the car isn't already on the bump-stops then removing the 20A suspension system fuse from the engine bay fuse box will prevent it lowering which means that the vehicle can be driven if everything else is OK. A warning beep will occur regularly but removing the 5A suspension system fuse from the passenger fuse box will stop that.

If you don't already have a way to get extra height for off-road use then consider fitting either GOE multi-hole height sensor rods or the LLAMS kit that I produce.
