My standard tire size on the Corsa was 165/70/13 but when I bought it had a very unusual configuration, 175/70/13's on the front axle and 155/80/13's on the back...
A few months ago I needed tires because the back ones were in a bad shape so I was looking for that exact size (155/80/13 but it was very difficult to find, only pair I could find were Toyo's and for some reason a pair was costing 110 EUR (over 150$) so i decided not to spend so much on a pair of tires.
The ones I ended up buying 175/70/13's, Dunlop's and I found them quite satisfying, especially when it comes to being very-very quiet...
Anyway, I'm rambling here, I just meant to say that I also went for wider ones because of lack of availability/pricing and also because one axle had that size already so I thought it would be better to match it..
According to "
Green Seal" the lowest rolling resistance tyres are the Bridgestone B381 P185/70R14. But I guess that doesn't fit your car
