I believe that it is not the saving of money which is the issue but your choice of tyres and brakes which is important, if you can get the same quality for cheaper then hey ... Im all for saving money ...and all for having good brakes and tyres...
I have been running a set of Falken Azenis tyres (they are a semi slick bottom range race tyre...too crap to race but too soft for the road type of thing) 225-50-16's for $190 ea.
They have lasted about 10,000kms... not bad really. They are about as grippy as a normal tyre when cold, if you really go for a blast and get them warmed up they perform quite well. One of the main benefits is the stiffer sidewall, very predictable etc.
