...is this still done at service time, or does anyone do it at regular intervals (assuming you don't have a staggered set up? I ask because they seem to still do it in the US).
I do it on my wife's X type (Non staggered wheels) as its front wheel drive it keeps the wear pretty even. Only down side is all the tires will need replacing around the same time.
He also recommends running higher front tyre pressures than rears on Mercedes RWD models, which is incredibly dangerous on a rear drive car.Good post...
1. In the olden days we used to rotate wheels clockwise including the spare, however nowadays most cars do not have a proper spare, and also there are suggestions that it is not a good idea to reverse the direction of rotation of a tyre once it has bedded-in (though Tony WIM seems to think it is OK to do so).
Tyres start with 7-8mm of tread. So are you saying that you replace when 1/3 worn.2.because my annual mileage is very low these days on both cars (said that, this is just me being overly pedantic about having even tyre wear all around - for the ABS/ESP and so on - I have yet to replace a set of tyres because they were worn - it is usually a combination of the tyres' age and me wanting something new... as result my tyres get replaced at 4-5mm, and always as complete sets).

why so? surely it will promote understeer - just like running narrower fronts...
It will promote snap oversteer, a situation most drivers can't handle.
Maybe if we had more factual posts on this forum, members would be better educated in motoring matters...
How about you mow down a bus queue of people and your insurance company void your insurance because your tyre pressures are outside the prescribed limits to give you more of a thrill?I would have thought there were other factors at play rather than just tyre pressure - sidewall stiffness, tyre construction, camber and castor.... I can see where you are coming from but it isnt quite that simple..
perhaps my comments regarding this are more track than road focused of course...
Personally I like a bit of oversteer and it doesnt intimdate me..... obviously were I an overstretched lease car pilot who would struggle for repair costs were I to modify a hedge, then I would perhaps be more circumspect.

I remember going on a Rolling Road tuning day and there was a 600Bhp Supra there with bent up rear end components.
The driver thought traction control was for woosies.
As far as tyres.
obviously, if you fit Michelins on the front and chinese ditchfinders on the rear you are altering the dynamics, but if we can keep the thread on this planet and you fit one decent brand all round, the tyre pressures alter the slip angles, hence they are set as prescribed by the manufacturer.
Hold the agression Will, I am trying to have a sensible conversation with you.
It is really very simple - the less front end grip a rwd car has compared with the rear the more likely that the oversteer will be "more violent" when it comes. This is fact - I am not disagreeing with you.
I merely pointed out that tyre pressure is not the only factor that can "invoke" this trait or counter it.
