In addition to the kid, we just got a new (used) car: 2001 Honda Civic EX. It needs new tires (private seller, knocked down the price a bit because of it.) I called the tire shop our (trusted) mechanic recommended, got some outrageous prices on Yokohamas, and asked about Kumhos. Reviews tend to be good on those. In any case, he said he had some in stock, but they were of a slightly different size than the car called for. The car says 185/65HR15. The tires he mentioned were 190/60HR15. He said that the circumference was the same in the end. I thought I understood tire sizes, but apparently not. Can someone shed some light on this? What will using a slightly wider tire gain me in terms of performance, safety, treadwear, etc?
