When I spoke to Toyo direct a week or so ago, Alan said supply this year (2012) could be a little better, but some sizes ( Exige) may get harder to find in the Summer. I think he said in ‘tyre sizes’ for a manufacturer they are low volume, or odd sizes to the norm’ . I can’t fully remember the minutiae .
As Mike says, 888s are superb (although others on here prefer Yoko 48s) - given the supply shortage, the price will be the price! Whilst I can’t fault Camskills, you need to also budget for fitting & balancing - say �15-�20 per wheel.
I found the best results (especially with 48’s) come from the tyre balancers that use the finger plates which hold the wheel to the machine by the 4 bolt holes rather than the usual machines you find in Kwik-Fit and the likes which use the centre hole.
