Federal SS595 SUPER STEEL 145/55 R17 Alfa Romeo GT 1.9 JTD 3,000 miles January 20, 2011
Okay so these were a bit of a gamble, but the Toyo Proxes I have been using just wear out too quickly (12K - 14K Miles) and a puncture on new year's day meant I needed a quick and cheaper solution.

They are good tires! The wet grip isn't quite as good as the Toyos', but not by much, and the general handling and feel of them is fine. Road noise is a little different but not intrusive. Wear seems to be even although I haven't done many miles on them.

Definitely worth a try.
