Thread: 20" at tyre pressure on sand

I have found command shift technique very good when off road, it keeps you in the right rev range so you do not experience any turbo lag.

Robert Pepper also teaches this technique as well as Gordon.

Happy New Year!

Terrain response and command shift are not mutually exclusive - they can be used at the same time. Command shift is just switching to manual mode on the gear box, terrain response is the special programs that allow you to tune the car to the different driving conditions.

Gordon is saying to use command shift to force the car to hold the gear you select so that it does not change gear at an undesired time. It allows you to keep power and torque constant as you make a maneuver.

No problem keeping it in auto though it will more than likely be fine.

Ive only done 1 serious bout of off-roading in mine,the sand tracks to West Cape Howe.
The command shift with the paddles was brilliant.I rarely use them on the road,off-road was awesome.

Exactly - the terrain response programmes adjust very specifically the vehicle's responses - the computers in the car read inputs every 500ms and can adjust the systems as quickly as 50ms (that's 1/200th of a second) - now when I was a young buck I thought I had reactions that fast - now I'm older I realise I was just lucky.
Google the terrain response systems to understand the different characteristics.
Or even better - buy Gordon's (green oval experience) book - it explains the systems in terrific detail

We have just spent the last two days exploring around Moreton, I have 20" rims on my sport with bridgestone highway tires that are due to for replacemnt in about another 10,000km, want to change back to 19" so didn't get a chance before we came over.

Dropped them to 25psi and have been all over the island, just put the terrain response in sand and let it do its thing, have needed to put the suspension in offroad height a few times but got away with standard for the most part. We only had one issue where the sand was super soft and got pushed out by a couple of blokes with were with, a disco 4 with 18" that were aired down just drove through with no issues, but lots of cars had to be pushed or pulled out.

Great success for 1st trip on sand at beachport, had no problem dune or long climb. I did not use command shift, but auto with sand terrain works well on many occasions.

Sounds like you had fun. I noticed that Gordon is offering sand training at Beachport in Feb so we are going to that
