Bridgestone Ecopia EP422
Initial Review: 2,000 miles on tires
December 06, 2011

These tires, in size 205 50 R16, replaced the stock 185 55 R16 OEM Bridgestone Turanza EL470 supplied with 2009 Honda Fit (Sport trim level).

The two biggest improvements are in ride comfort and fuel economy. Whether it's the tire or just the larger footprint and changed sidewall geometry (the 205 is about a half inch wider on each side of the stock 6 Sport wheel), potholes and sharp ridges are much smoother under this tire. THe tire is also somewhat quieter, except when driving on pavement with rough aggregate or grooves (as in the Houston area, for example). On such surfaces, tire noise is slightly higher than OEM.

Hydroplaning resistance is good, though I was able to induce it on rutted highway pavement with standing puddles (US 31 in AL, south of Montgomery).

AT stock pressure, the tires felt soft and unstable at highway speeds. Increasing the pressure to 39 PSI on all four wheels eliminated that problem, and the stiffened ride is still better than stock Turanza OEM (which apparently are now only available as a dealer part; only the Dunlop OEM remains available as a replacement tire). The go-kart steering responsiveness of the Fit Sport with stock 185 tires is reduced by the wider tires, but it's a minor change. The wider tire feels much more robust in hard cornering, especially over irregular pavement, provided that they are run at higher than stock pressure.

Fuel economy on the road increased by a full 4 MPG at 70 mph, from 34 to 38 consistently. On recent road trips with brand new tires, mileage would not dip below 38 mpg even with some hard driving and urban segments. CIty mileage seems unaffected, but not enough data has been collected. (OEMs were also run at 38-40 PSI).

Second-generation Fit Sport owners despairing over replacing the stock size should know that Honda supplies the 205 50 R 16 on the Mugen wheel. The Mugen wheel 1/2 wider than the stock Sport wheel, but nearly the same offset. No clearance issues experienced here.
