I fitted these when I fitted my CSLs a few weeks, and a few hundreds of miles ago. The do look great, but I find the front of the car tends to wash out just a little when taking tight corners at speed. I've noticed also more tyre squeal from the rears on rapid acceleration. I am unsure whether this is due to the tyres being new and having not yet lost their surface chemicals, or whether they simple don't grip quite as well as my previous tyres. I suppose also it may be a consequence of increasing the wheel size, but I suspect not.
Has anyone else found these tyres take a while to bed in properly?
