I also deflate about 10% just for some added comfort. Previous vehicle could easily do 110 loaded. Haven't had the time or opportunity to see how my Ft behaves on gravel. I know the previous owner used it for touring, I'm hoping that when I get a chance to peak under the wheel arches again, I find something other than the original shocks in place.

4L vs 4H.(Locked center diff) (1) The added fuel consumpsion is negligible compared to the added safety, not only of yourself, but also you passengers. The added wear & tear is also negligible. A difflock only really works "hard" in very uneven terrain, on normal gravel roads it will not really work hard unless it is needed.

4L vs 4H. (Locked center diff) (2) Locking the center diff couples front and rear axles together via the drive train. Braking force is also therefore distributed via the drive train from front to rear. This decreases stopping distances. Fact. We have tested this many times.

Tyre deflation. (1) Tyres are your primary suspension. It is the first point of contact with the corrugations. hard tyres do not absorb the shock of corrugations, leaving that to the springs and the shock-absorbers. If shock-absorbers work hard they heat up, and as they heat up they become less effective. This leads to shock-fade, causing the tyres not to be in contact with the road any longer. No contact between tyres and road = no traction. Couple this with 100km/h and you are a passenger in a very expensive rollercoaster.

Tyre deflation. (2) Bigger contact patch on the ground means more friction area when applying the brakes. Deflated tyres decreases stopping distances... Fact.. We have tested this many times.

These are enough reasons to engage the center diff and deflate your tyres when driving on dirt road. I see somebody said that it increases fuel consumption? And wear and tear? Reduce your speed a little and it will be cancelled out. Be safe out there guys... Fortuners dont have a very good reputation when it comes to dirt roads, although I believe firmly that it's not all the car's fault but rather driver error...

Yip - it surely does make sense to deflate - just remember to inflate again when travelling on tar

Yip, that fuel consumption difference is so small comparing to the safety

As with everything you need to find the happy medium.

If I am driving 1000km on tar and there's a stretch of 5km that is gravel... I dont deflate either, but I do slow adapt my speed to the conditions to protect my vehicle and passengers, and engage 4x4... If, however, my trip is going to be over 100's of km's of gravel roads, I also deflate the tyres....
