Yes, calibrated against a navigator. I think I drove about 120 km so it should be accurate.
The wheels I tried was what I had at hand at the moment. I do think that 175/70-14 would fit as they have about the same diameter as the 185/65-15 but are narrower. Anyway since I don't get the desired result maybe I'll stick with the original 155 mm. I can't find any 165 that I want i.e. Hakkapellitta for winter or Michelin Energy Saver for summer. Otherwise I would probably had tried them.
I didn't see the 165 Michelin so thanks but right now I'm looking for winter tyres and have decided on Nokian Hakkapellitta R. Still have to choose between 155/65 or 175/65 or 175/70. The last experiment tank was not in favor of bigger diameter.
How did you find the effect on acceleration or maintaining speed ? I think this is where Aygo's lose out. City driving only I can easily get an MPG into the 70s, as soon as I hit the motorway it drops to low 60s at best.

It was noticeable but not a problem even with a passenger and some luggage, except on FE. I still don't know if it is the grater load on the engine or worse aerodynamics that caused the increased consumption. Now I have the conti winter tyres on and two of them needs to be replaced: 175/70 or 175/65? Or maybe stick with the 155/65.
From fourth to fifth EcoModder Fleet list - EcoModder.com Damn cold weather. The two new Nokian Hakkapeliitta R doesn't seem to help either. I finally decided on the original size 155/65 as replacement for the Contis.
I have been forced to partly drive on faster roads on the other hand so I guess I shouldn't complain. And 90 days at 62.65 mpg isn't really bad.
