Bad fuel economy

[LocalFart]

Yeah the fuel gauge will always be a bit off for the first quarter because most ppl over fill their tanks...

But have any of you guys thought of having two sets of tyres? like I have some 265/75/R16's that I will put on when I take the car out and drive around town with 205/70/R16's and get 10km/L or better?

I stop at the first click and thats its i dont try put more in.
If i went to 285/75 i would think about, but i go away lots i could see it been more of a pain in the arse,
I guess with a good trolley jack and rattle gun,it would be okay but i dont have either of them yet..
