Get a 4 wheel alignment done, dont rely on it coming out of factory set correctly. I noticed some feathering on mine after some towing and carrying gear in the boot, and i got the alignment settings in the rear as close to it's less camber setting so when the car is loaded up it has less effect on the tyres. I've managed to get 60K out of my Dunlop SP SportMaxxx, but they are an average tyre in my books. I'm booked in for it's 60K service on Monday and a new set of Goodyear eagle F1 Asymmetric 2's - really good reviews, ( google search em ) , and the wear rating on them is better then the Dunlop SP's so I hope to get the same if not better out of these tyres. They are costing $378 per tyre fitted and balanced. I was looking at getting them from tirerack.com, but really i was only going to save myself about $150 once fitted & balanced so decided to keep the money local.
