For the record, the OEM Firestone GTA tires on SE's are a different tire than even the same tire you would get from Tirerack or your local tire shop. OEM's work deals with tire manufacturers and often produce a lower quality tire with the same name for OEM. This benefits both companies in that the OEM gets a better price and the tire supplier gets the repalcement business sooner. I have heard of people buying the exact same Firestone tire as replacements and the difference is amazing. Not hard, handles the same, and lasts twice as long. This doesn't mean I recommend the Firestone GTA, but if you buy them aftermarket are not nearly as bad as the OEM ones.
For the money and all-season purpose, the Dunlop SP Sport A2 is the best buy.
