IMO the 888's are the better tyre and they will stay road legal for longer.

I tried some 265/45x16" Kumho's on mine for a while. But due to the tread design, after only 1k they would be deemed illegal.

They only had 3 full depth sections of tread, the outer edges had reduced depth. Because of this, it would fall foul of the 1.6mm over 75% of the tread width rule.

Narrower tyres might survive longer though.

The 888's are just a bloody good tyre
