Wow. I can't say I expected quite the number of replies, but did expect some of the comments.
I did not want to have the expense of fitting premium tyres, particularly as I was only replacing one, which is unlikely to make any difference in isolation.
Yes, I know tyres connect you to the road and are a big factor in safety, however, weighing up the way I drive, risk, safety bonus, etc. I am content with mid range tyres (i.e. nothing that's rolled off the back of a lorry, but not £100+ a corner either). Perhaps you don't share this view and would rather have premium tyres. I have no problem with that; we just have difference attitudes to tyre purchase at the moment.

It seems to get a reasonable (albeit limited) review and placed as a mid range tyre, so I'll hold off updating my will just yet.
I will let you know how I get on. If you don't hear from me you can assume I'm in a ditch and you were right.
Plus, the bear is pretty cool!
