Cold pressure

Hi Guys,

It's been a bit quiet in the 90's section so...

I was having problems with uneven wear on my rear tyres (Bridgstone 265/70r16) The outside lugs were getting all the wear and to me this meant too low tyre pressure. I was running at 37 psi cold all round (Maxxis 751 on the front)

I stopped into a Toyota Service centre to get an opinion and he said they run all their Prado's at 40psi cold all round...

Any thoughts... what do you run at, for day to day black stuff driving.

I think the pressure you run will be entirely dependant upon the actual tyres you use, and the weight/load you're carrying.

I run Cooper STT's in 265/75R16, and to keep even wear on the blacktop, I find that 35psi (cold) is just about spot on. That's with constantly loaded storage drawers and water containers in the back.

I have found though that the STT's have a very stiff sidewall compared to the old BFG AT's I had on before. (Have to air down an extra couple of psi for soft sand to get the same lenghened footprint for sand driving, etc).

Anyhow, the info maybe of help to someone.

I currently run Cooper AT 265/70/16. As I do a lot of caravan towing as well as carrying a lot of gear in the back and roof rack the rears are usually at 45 PSI with the fronts on around 35-40.

I noticed the damned Toyota Service keep letting the pressures down, bless em.

I have noticed greater wear in the centres. Need to keep on top of the tyre rotation. Spoke to Cooper who suggested a light truck construction to avoid that as they have stronger side walls and increased strength in the centre.

Gidday Guys,

Well after a week of trying different tyre pressures (with no luck at all) I finally tried 46psi (warmish) and drove a couple of klms.
When I got out and looked it had the same wear as usual, scalloping on the outside lugs, nothing on the inner pattern, so figured it can't just be preasure. :?
On the way home, I thought I'd find a Bridgstone dealer and ask what they recommend.

He was very helpful (Bridgtone at Wynnum) and shed some light on th e matter for me...

He believes that the tyres (Bridgstone 693) would have been on the front end before I bought the car back around July and probably were wearing unevenly back then. Since being moved to the back they will wear back hopefully to an even tread after maybe 10,000 klms or so (he guesses).

As for pressure, he said between 35 - 40 psi but no higher.
So, I have gone for 38psi as I carry a bit of gear in the back most days.

Oh, and he tested my bushranger digital tyre guage for me and it's reading 2 psi under :evil:
