Tyre pressures

[Barney2803]

Hi guys, a question on tyre pressures for continual on/off road driving.....

When I replaced my tyres last year I didn't feel I could justify the extra cost for A/T's as I was intending to be doing 60-70km a day on bitumen when we moved. However, now we've moved I found some dirt roads that make the trip very enjoyable and so I do half of the distance on dirt, about 150-200km over the week.

So, what pressures should I run in the tyres considering I'm traveling dirt and bitumen and some of the dirt sections that have quite a lot of gravel/rocks that I take at 80-100kmh

They are highway slicks, 265/70/R16's.

Thanks!

Slow down on the dirt / gravel / rocks sections.

If the dirt roads are good enough to drive safely at 80-100kph, then it's not off road & regular road pressures will be fine.

I only drop pressures for real off road stuff, where extra traction at slow speeds is needed (5-10kph).

here is one that hasn't been asked b4. omg

do you want it to oversteer or understeer?

The roads are dead straight, and for the experts, no I'm not stupid or a know-it-all , if I was then why would I be asking for some advice?

Cooper Tires have a tyre pressure guide they will send you for free.

If you are only doing 40km a day on dirt, I would just slow down on those sections as I said before.

Ie. Keep your tyres at road pressure and then take it easy on the dirt / gravel / rocky sections.

For what its worth I agree with what Scouse says.

Some vehicles handle dirt roads far better then others on 'street rubber'. I found the D2a was really good, the D3 even better.

Though I have driven a number of SUV type soft roaders that are truly scary on dirt roads.

cheers,
