The 15 inch wheels and Avon CR6ZZ tyres are one of the best improvements you can make to any later Cobra. I have a set on my own CRS and love them and have recommended them to many other owners. However, they have one draw-back and it must be considered as a recent experience in my CRS reminded me. The Avons are road legal units based upon Avon Racing Intermediates, not wets. They are fantastic in the dry, once warmed up and good in damp road conditions if treated with respect however, they do not have a tread pattern designed for heavy standing water. The tyre cut grooves have little or no way of passing any water gathered in the centre of the tread out to the sides of the tyre, to clear it. A little enthusiastic cornering round a Milton Keynes roundabout, after hitting a small standing puddle ended with a side spin and off, across the grass verge and into a hedge, narrowly missing a large concrete lamp-post. A very chastening experience. The car gave no warning prior to it change of direction and catching it only partly redirected its sideways momentum. No damage done, apart from my pride. It just reminded me though, Cobras bite and the Avons are not for very wet usuage.
