I opted for a set of Falken 452s (2 x 225/40R18 & 2 x 255/35R18) from Camskill which cost me £375 delivered. Excellent price and my local tyre place couldn't come anywhere close. I then found a place which could recondition my alloys for £50 per wheel. I had a set of tyres so I thought I'd kill two birds with one stone and have the wheels done the same time the tyres were fitted (they were going to charge £15 to fit and balance new tyres anyway!). So off I went...
Just picked the car up today and the wheels are immaculate, much better than I had imaged. I also bought some replacement 'M' badges and BMW centre caps, both from eBay as mine were also looking a little tired. Another bonus was that one(!?) of the front Bridgestones was still usuable so I am going to eBay that today.

All this for £575. Bargain of the century!!!
