|I made some
research and compared different tires that can fit into Jazz.
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;
|Criteria for awarding the eco-label RAL-UZ 89 to low-noise and fuel-efficient summer tyres|
|Size||Tyre Model Tested||Roll-frictional Resistance (cR=1,10)||Mass (m=7/9 kg)||Noise* (L=72dB(A))||Braking on wet surface (sB[m])||Aquaplaning (vA[km/h])|
|Marshal||Power Racer 65V||1,18||10,50||71||49,25||95,8|
|*Rolling noise at 80 km/h measured at a distance of 7.5m on a standard test track|
Continental EcoContact and Michelin Energy were looking as the best choices. Called the dealers and I got 4 Michelin(s) with 14'' rims.
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.
