Thanks for that info. I have that manual but havent read it with thought yet.

Reason is propably the eco mode switch, because I havent used it more than few test accelerations and newer on stanstill. Will try that also on tomorrow when I will drive it to Neste Rally Finland .

Used 175/80R14 tires were able to rotate on the Lupo 3L but bad noises come at turns from driveshafts so did only short test run and fuel consumtion meter showed 3.3 liter but road was now also damp due to rain than the previous todays test was 22 celsius and dry. Difference in diameter is 14% so if the fuel consumtion was 3.3 that makes it better even on rain and much wider tires. 3.0 l/100km --> 3.42l/100km. I think good diameter would be something like 8-10% taller tires. One good choice i Toyo 310 in 155/80R14 which I will most likely buy. First I need to test some tires with same diameter that will those make also the same noise.
