Tire Exchange
ES model is coming with 185/55 R15 Bridgestone Potenza RE040 82H tires. These tires are in Ultra High Perfromance category, Honda deserves applause for putting those expensive tires to an unexpensive car. Those tires provide good grip handling and braking but lacks comfort. Jazz 1.4 is not a performance car, it doesn't need those sport tires. On winter you need an extra set of snow tires.

Customer surveys on tirerack.comalso states that.

To get a comfortable ride, tire exchange is a must. 

But whatever brand you get, 55 sidewall is always sporty, hard and noisy.  

 

I made some research and compared different tires that can fit into Jazz.
  185/55 R15 195/50 R15 175/65 R15 195/60 R14 175/65 R14
Diameter (mm) 584.5 576 608 589 583.1
Price (US$) 130$ 150$ 105$ 65$ 58$

I need to keep the new tire's diameter as close as to the original tire. As I want a more comfortable ride, I need a sidewall of 60 or 65. And there's no tire size with those profiles that I can fit into 15'' rims. So I need to change the rims to 14''.

The closest match to my tires are 195/60 R14 and 175/65 R14. 195 provides better handling but makes the steering wheel heavier. And this size is hard to find.

175/65 R14 is very common and the cheapest of all. Then I needed to chose the brand having the most silent characteristic. Yokohama has a model called Yoko AVS Db but it's not available in Turkey. By thinking the softer the tire, the more silent it's, I decided to go with all touring fuel-efficent tires. I searched the net  and found following German TUV test results;

Continental EcoContact and Michelin Energy were looking as the best choices. Called the dealers and I got 4 Michelin(s)  with 14'' rims.

 

Result

Rolling noise has reduced as expected. 65 profile tires give a smoother ride. Unevenness and small bumps are not felt as before. I don't have a decibel instrument to give the exact results but my friend has another Jazz which has original tires. I call tell the difference by comparing them. I didn't see any difference on handling and braking. Actually I feel like new tires braking better on rainy roads.

I spent one hard winter with those new tires. As energy tires are soft and they have silica in their structure, they provide decent snow grip.
