Here we go, more info from Goodyear's website.


Eagle F1 GS-D3
Dry Traction 9
Wet Traction 10
Snow Traction 2
Ride Comfort 5
Quiet Ride 6


Eagle GS-D
Dry Traction 8
Wet Traction 8
Snow Traction 2
Ride Comfort 4
Quiet Ride 5


Eagle RS-A
Dry Traction 7
Wet Traction 8
Snow Traction 8
Ride Comfort 7
Quiet Ride 8

According to Goodyear, there's no reason to continue using the GS-D, even if comfort/quietness is a consideration, over the GS-D3. I added the RS-A here, as it's the all-season performance tire that comes as standard equipment on G35's. The other standard tire Infiniti uses is the Bridgestone Turanza EL42. However, Goodyear's website doesn't seem to have 1-10 ratings for this tire, for some reason... anyway, the Turanza is an all-season touring tire. It gets much better marks than the RS-A for comfort and quiet, and poorer marks for dry traction.

Thanks, Ryoken. I am going to go with the F1 GS-D3. The price is not much more than the Toyo Proxses or the Bridgestone PP. I live in So. Cal. so I don't need all season tires. The only problem is that everyone is our of stock on the sizes I need.
