I’ve received the tires and did the mounting myself. It was actually much easier than I expected, I managed to seat the beads with a hand pump. Original rim/tire combo weighed in at 10,6 kg. New setup is at 13,1 kg which makes 5 kg more rotational mass. I’m not too concerned by that since 95% of my commuting is at constant highway speed. I did a quick round trip around the neighborhood to test it. Only problem, the tire is touching the edge of the front bumper when I steer. That’s a matter of millimeters, I’ll see if I can slightly move it forward, if I can’t I’ll remove some matter (it’s plastic). Else, no problem with the suspension and full steering. First impression is much worse accelerations (mainly due to the ratios, not that much because of the weight). Steering feels still OK despite the width.
Each gear will have a 10% higher ratio, 5th gear tops at 39,8 vs 36,2 km/h at 1000 rpm. At 80 km/h, RPM drops from 2208 to 2011 RPM.
My speedo will actually be exact because I had a strange 10% overestimation with the originals tires. The distance will be underestimated by 10%. Not really a problem, as long as I consider it for consumption and maintenance intervals.
It didn't take me long to get other's attention. I passed by a car part shop with 2 people at the entrance and they stared at my front wheels (like "What the hell are these tires on that tiny car ?"). They still looked at the car when I was 200 m away. Their faces were so funny.
No pictures yet, but it's true that the tires seem gigantic compared to the car.

We have had low temperatures lately (0/8°C) and that’s noticeable on my consumption. I have a hard time getting under 3l despite the grill block.
