Lightweight sedan, about 1100kg empty mass, FWD, 86HP 4-cylinder 8-valve 1.6 liter atmospheric engine, 2004. Dacia Logan 1.6MPi.
Usually drives only me around, as such driver side is the loaded side.
The tires threads are still about 6mm.
Regarding total tire mileage I'd have to check my notes, but they are in use 6 months a year and I rotate them annually , I purchased them 2017.
I don't drive much, 3-4k Km annually, mostly town traffic.
They are Continentals, very soft and when they were new they held on to the tarmac phenomenally - they are starting to loose grip though.
My car gets an annual checkup at the Renault dealership, I have no clue whether alignment is being checked.
I have no problem purchasing new tires, I am on my 2nd summer and 3rd winter set since I bought my car.
I don't change tires when I wear them out, I change them when they loose their characteristics/grip.
