As far as tires go I have only used Bridgestone Spitfires and I haven't heard anything bad about them. I certainly have had no problems with them and they are the cheapest sport-touring tires that I can get here except for Kenda's(which are a cheapo tire company). The rear tire lasted about 11000km (6820mi) and I just replaced it, while the front tire still has some tread left.
The most popular brands are Dunlop, Bridgestone and Metzeler. I think most of you have installed sport touring tires like Dunlop's K591 and Bridgestone Spitfires as well as Metzeler 33/55. If you have any info on tires you have used then please email me what brand and model, how long they have lasted as well as how they handle. Thanks.
