I see Maxxis Tyres Have now come up with the ZR9 which looks like a R888 type track tyre. Anyone know anything about these Tyres or used them? It seems Maxxis are trying to take over the world…along with Red Bull.
Here we go - interesting review 
Looks like it performs well in worm weather !!!

Maxxis ZR9 Victra Reviews:

Driving on a combination of roads for 1,000 spirited miles
This is a semi slick tire. Maxxis is not a well known company but it is a respectable one. The tire has very stiff sidewalls as a semi slick tire should have so it is very very responsive but not at all comfortable as expected. The rubber is R compound but I have been using it in the street in Greece. Even in 10 degrees Celsius temperature and without being warmed up it grips like an ultra high performance tire. In worm weather and after being warmed up it grips much more than anything I’ve ever tested before. (Potenza RE040 , Michelin Pilot Exalto , etc) In wet though you shouldn’t try going out at all. It is scary besides it has some grooves. I am very pleased with it , you can have a lot of fun with it in dry conditions and its price is very reasonable. tyre reviewed on April 24, 2009
