Kuhmo Ecsta LX...
For what it's worth, I replaced the OEM Toyos after 31,000 miles recently with Kumho Ecsta LX Platinums. Size is the same as the OEM Toyos (205/50-17). I got them from tire rack for $118 each.
After a couple of weeks and about a thousand miles, I'll give them a hearty "thumbs up".
First thing apparent is how much quieter they are than the Toyos. Now, since the OEM's had more than 30K miles, it might seem a bit unfair to rate the Toyos as noisy, but they did seem noisy from day one. Maybe a ride in a new '09 might not seem as dramatic, but they do seem much quieter.
Handling seems equal to the Toyos. No squeals on turns or anything like that. Also, a big difference in the wet. In the past week, some tropical rains (thanks, Danny) have drenched parts of the southeast. Hydroplaning resistance is much improved and there is a noticeable improvement in traction when starting uphill on a wet road.
I'd sum the Toyos up by using a work that came to mind after a day or so riding on the Kumhos...they make the 5 feel somewhat more sophisticated. A lot of the noise transmitted and resonating through the body structure is absent with these tires. The whole car feels better put-together and more "expensive" with these on. So, at least for me - an average driver using my car about 40 miles per day in suburban southeast US conditions (with some "sporting" pretentions) - I'd say the LX Platinum seems to be a good balance of refinement and good handling. We'll see how they go from here...(thumb)
