I replaced my Bridgestone Ecopia 422 Plus with the Accelera Eco Plush on my 2013 Prius. Mileage has gone down from 52-53 to 42-43. At first, I thought the tires just needed to be worn in but after more than 5K miles, I'm resigned to the new normal. Gas is purchased at a Costco in LA, and there are no other changes to driving habits. It doesn't even feel noticeably different, aside from the surge of anger when I see my mileage. The Ecopia's cost me ~$100 each at Sears in 2018. This time, the Acceleras were $380 for the set vs upwards of $600 for the Ecopia's. A smart man once said to never go cheap on anything that comes between you and the earth - shoes, socks, tires. I am not a smart man.
What prevents you from buying new Bridgestone Ecopia and selling old tires Accelera Eco Plush? When they are not too worn out they can be sold at a small loss.
I just bought 4 of these: Hankook Kinergy PT (H737) 195/65/15 91H So far, the mpg is the same, maybe slightly better? Haven't driven enough to be certain. Certainly didn't lose any. Bonus: VERY Quite! Very Smooth, and a softer ride. I am VERY happy with them so far! If they last the 90,000 miles warranty, I'll really be happy! I have Hankook H267 I think they were. Handle well, not super noisey, decent mpg, but didn't last 40,000 miles....
$100.57 each. Plus tax etc..... I always get lifetime balance&rotation, and road hazard. It was about $500 for all 4.
Depends on the cost of a gallon of gas in your state. At 2.2 a gallon, you can fill up 100 gallons and drive 4,200 miles for the difference in the cost of a set of tires. At 3.6 a gallon, you can fill up 61 gallons and drive 2,562 miles for the difference in the cost of a set of tires. You can calculate the efficiency over the life of the tires, say 40,000 miles. For MPG 52 you will need 769 gallons, for MPG 42 you need to fill up 952 gallons. The difference is 183 gallons, which will cost clearly more than $220 from the difference in the initial cost of the tires. Gasoline in any state is more expensive.
