I'm running 245/40-18 on my 02 Maxima and I get an avg. Of 28 mpg on these, they don't hold well under fwd power load, meaning they spin easily but they are ELRR tires! They are soft compound tires and very quiet and comfortable. Not the best for PA mountain cornering but for the sunshine state FL, they are perfect as went don't have mountains or pot holes here. But everything is miles away. I bought a used set of 2 for $80 and made 16k miles on them but my control arm bushing failed and ate one tire badly. They don't make much noise when you spin them, but leave nice tread makes. If they were $40 cheaper, I'd buy a set of 4!
