I've just bought some 16" OZ Super Ts with Toyo T1S tyres. Best deal I could find on the net was £640 + £25 delivery. Found them separate for £600, but with p+p and then someone to put the tyres on the rims (about £15-20 a corner) it wasn't worth it. So I rang my local wheel specialist South Coast Wheels and they done them for £675. A £10 more, but worth it for a local place if there's any trouble, and they're chucking in a set of locking wheel nuts. Give your local shop a call, you could be surprised at their prices. Supports local business too.
