Hey guys, new to the forum. Wanted to ask what tires you guys are running on the Prius 5th Gen. I have a 2024 LE FWD and I live in Salt Lake City so mostly dry driving with a bit of wet and very mild winters. Im trying to find tires that focus on fuel economy because so far my MPG has been excellent and Im wondering how much further I can push it, especially with the price of gas and insurance right now. Currently, Im averaging 63-64 MPG each tank according to the Trip Computer. Napkin Math puts it closer to 62 MPG. Work is only 7 miles from home but I do take long trips once in a while such as going to Colorado once per year. The car is at 35K miles and the Toyo Extensa Tires that came from the dealership are pretty much completely dead. Since its the LE, the tire size is: 195/60R17. This oddball size does limit your options a fair bit. Tires I am most interested in so far: Top Pick - Bridgestone Ecopia EP422-Plus - Lowest Rolling resistance rating available in this tire size while still being a GT All-Season tire with decent grip in all conditions. 600 Treadwear Rating and known to last about 60K miles. Tires were released in 2015 so they are well-established. $195 Each Hankook Kinergy XP - A much newer tire technology released early 2024. It doesn't have a specific eco or rolling-resistance certification like the bridgestone, but it does have a more modern and more advanced Silica compound, is known for decently low rolling resistance, has a 720 treadwear and a 75,000 mile warranty. They even cost less at $180 each, but they can't offer the same fuel economy as the Ecopias, so over time the Ecopias fuel savings would likely make up the cost difference. Least Likely to buy - Goodyear Assurance Maxlife Gen 2 - Hugely Long lasting with an 820 Treadwear Rating and an 85,000 mile warranty, but its clearly compromised in exchange. The tires are known for sub-par heat dissipation and are known to be quite loud and firm. They also have the worst rolling resistance of the 3 options. They are also the most expensive at $200 each, but you can't help but be impressed by the tread life.
I’ve got 12000 miles on Ecopias. They seem to be working out so far as far as wear and mileage. Time will tell.
