In the south of France in the summer, where I have my M3W, not too concerned about wet weather grip. When it does rain, the roads are very slippery as all the diesel rises to the surface, so in any car, I am very careful. I will bring a pair of Blockleys down with me when I come down next spring. Is there any reason not to reuse the original tubes (Avon I presume) or is fitting the HD Blockleys advisable. I am sure if I just ask Julian (Mazjub) he will say "essential dear boy!"
