Tyre pressure (again but different)

I had a 98 Pathfinder with Uniroyal Laredo A/T tyres on it. They were pretty useless at stopping on a wet road especially at high pressures because the rubber was so hard. I used to run them at 26 psi and got 120,000 kms out of them. I like the more comfortable ride and. I just traded the car with 360,000 kms on it and it had no rattles. Most of the 'bushies' I have talked to seem to think that we run too high a pressure all the time. Anyway, recommended will do me although I take on board others experiences. Cheers

Surely you're not saying the car manufacturers knows what they're talking about. Wash your mouth out. :-)

Hi. I don't pretend to know the answers: I have Tyredog sensors, and I notice that, when loaded and travelling at highway speed in warm weather, and with tyres around 40psi, that the hot running pressure rises by up to 8 degrees. This seems to mean that, to keep in synch with the 6 psi rule (which I hadn't heard of, only the 4psi rule) I'd have to go up to maybe 45psi plus.
I too go for low pressure on rough roads, especially where hard stone (gibber etc) is involved.
But for me to accept Toyota (26psi) means I would have to ignore all the other advice (tyre manufacturer, tyre dealer and 'learned articles' in the 4WD press). I am also aware that Toyota gives just one pressure figure, regardless of load, which doesn't gell with me.
If I have been running pressures too high, then how come I have not experienced tyre crown wear, rather then even wear?
I suspect that a simple 'one size fits all' answer isn't the way to go, but that we should all use common sense to choose pressure, depending on load, speed, type of tyre and particularly road conditions.

Oops. instead of "rises by up to 8 degrees", I should have said "rises by up to 8 psi".

Hang on, Fatso: 1980 was only yesterday. My first steel belted radials were in the mid 60s.
But all this really makes you wonder, doesn't it? How much sceince is there around and how much 'folk lore'?

Mike.
Bear in mind that tyres are excluded from the vehicle manufacturer's warranty. Perhaps that frees the dealers from sticking to the manufacturer's misguided ideas about tyre pressures?
I have never found a dealer who inflates tyres 'way beyond the manufacturer's ratings', and certainly not enough to make them unsafe. What are they 'getting away with', anyway??

Well I brought this up because I took my wifes vw to the dealer for a service and drove away feeling like I was driving Fred Flintstones car with rocks instead of rubber. As a side issue, what a ripoff dealer services are...ouch.
