Hey guys, I'm looking to change the RIMS on my car. It currently running on the stocked 16" ones (08 model). I'm thinking of grabbing some 17", might even consider 18" but I'm concerned about ride and noise. Grip isn't too much of a worry, as I don't take to the track. Of course, this means new tyres as well. Wondering what everyone's experiences are, especially compared to the stock Dunlops. Again, ride and noise is my main concern, Bob Jane reckons Pirelli P7 are the go, but there are a few bad reviews it would seem.

Also, anywhere I could get them cheaper? OzzyTyres seem to be very cheap, but struggling to find any I want. Considering these:

But pricing seems a bit steep. Also confused over the hole types (5h x 100, 112, 114 ect) not sure which ones mine are.
