I have a set of Fuzion ZRI's on my E1's (summer rims/tires). I just had them put on in April and they still have decent tread left. I've autocrossed once in them and run them hard during a few other corner turning exercises

as well as a trip to the drag strip. I am overall very pleased with the wear, but i agree the sidewalls are kinda soft, no matter what the psi. They are an awesome bargain summer tire
