Hi , the change is not to get better ride or handling.. simply I am up for new tyres and I can get a full set of near new 4 wheels and tyres with 85% tread for less than new tyres on my existing wheels (and I have to wait around 10 days for teh tyres to come out of the container in Melboourne..).. I am keeping the existing wheels and will put those back on when I sell...
