The Toyo R888r are a circuit track tire and fast road tire. The tire compound is soft, so bottom line is they do not last as long as a set of Michelins.
The R888r is not a Drag racing tire.

The Michelins will handle better in Wet weather as due to the tread pattern they will cut through water better than the toyo in road conditions.

But remember, even with michelins, you don't want any with old date codes.

You are lucky in the USA as I am using the Earlier Toyo R888 here in the UK as Toyo is not stocking the newer R888r in our country. Its also very hard for us to get Michelins as they are produced in limited numbers.
