Go for a run and see what they run at then set it up You do it on the headunit anyway

I found about 10- 15 above ambient was about right for normal temps

I'd set them for pressure.

Do they have a rapid deflation warning too?

Good suggestion heat varies with pressure When towing I worked on a 6lb rule in the tug and 4lb in the van.

So go for a drive for 30 mins and see how much the pressure rises. More than 6lb they are too soft less than they are too hard.

Some say 4lb all around but I found 6 better with a heavy load.

I had a full width mudflap on at the start of the trip and rear tyre temps went up to 65deg when rest were under 40. Took the flap off and all were similar,

Never used it agtain

50 would be enough from what I remember I had mine at.

Dont want it too hot or they might blow before it gets up to 70

What Tom said!

Maybe 45-55, and if you get false alarms just kick it up by 5 deg. Water at 53 deg is just too hot to stand on bare skin. A tyre at 70 would probably be those ones you see on side of highway.

Uppy,
We've just come over the Simpson in cool weather running 13/16 cold pressures which when hot were 16/19. Tyre temps went up to 65 degrees on the sunny side of the car and 58 in the shade.
Cheers

Yes that happens but I think temps running in hot sand would not equate to temps on the road.
Mine did run a little hotter on the sunny side but change when direction does. Found about 7-10 above ambient was normal.
