Thanks Athol getting a handle on the issue now .

Ok to those on here. Lets put it another way .

1  PASSENGER car  fitted with OEM 225/50/17   at about 280 a corner
for decent tyres


2 Desired outcome  save money on  tyres  no need for super duper high
performance
as mostly on dirt roads with pot holes etc    rarely rains


What tyres and size  would one fit  to give decent ride  and low
noise. and save a few sheckles

given that  roads will be chopped up further out here and recent
budget cuts means  no repairs  on roads (but 200% increase of traffic)
go figure ? Until 2012

getting out of the way of road trains on the few bits of tar  has the
potential to start chopping side walls  out of very expensive tyres

 what would you folk fit  to address this problem

Best priced tyre at that size  and even if go down to 245/45/17
still about 160  a corner on Chinese Roadstar Road stone  ?

If I was on 16' inch tyres options and pricing appear a lot more is
all I was saying .
However, have no desire to decrease or compromise brake  operations .
I am told 16 WILL fit but cooling is decreased .
Given that original set of pads is still in and  said by dealer to be
VERY ok after 60,000 clicks
indicates that I dont hammer the car or the brakes .

Thanks for the input by the way-- appreciated
