Fuzion is a Bridgestone brand. The ZRi has the same tread pattern as my Dayton Daytona ZR. I suspect that they are the same other than the name on the sidewall. I'm very happy with mine. I'm on the second set. The first set lasted 60,000 miles.
The guy at the tire shop claims that both are the same tire as the Bridgestone Potanza 750. I have my doubts as they do not have the same traction rating. I'm sure that the "value" brands lack something to help reduce the price. It does seem to be very close though. Anyway, if indeed the Fuzion is the same as the Dayton then I like it better than the Kumho.
