true, but i'd rather get better mpg's than tyre life. i'm not in the game to save money. the thread i was looking at was defender vs energy saver, and the poster was 'priusgto'.
51k. Stopped charging once I moved to NYC, ConED likes to charge arm and leg for electricity. Changed tires at 49K to Ecopia OEM tires MPG stayed about the same.
I think there's always a trade-off between mileage and ride comfort. Picture a flat tire rolling along: The rubber on the bottom gets squashed flat as it rolls, and then it re-forms as it rolls off the pavement. This creates "rolling resistance"; some of the forward energy which moves the tire is used to deform it as it meets the pavement. The more air you put in the tire, the less deforming and the less rolling resistance. That's why the 42/40 psi gives better mileage -- the car isn't squishing the tire flat as much. This puts less tire rubber in contact with the road surface, which can reduce traction. It also makes the tire less shock-absorbent, so more road noise and vibrations will occur. But mileage will be better. This is sort of a generalization, because tire and car design and other stuff play in. But, it's likely that the highest mileage tires won't give the most luxurious ride.
42/40 is the magic number on the Prius. I'm at about 30k miles. Tires are at about 50%. Dealer said I have about 10k left on them and then it was time for new tires.
Purchased Jan 29 2013, 55,000 miles, 18% EV. Same tires. Blame two drives to Taos N.M. from N.Y. for low EV percentage. Will switch to Michelin Defenders.......soon.
I finally hit $1000 in gas spent today on my 2014 PiP (and approximately $100 on electricity) after 10 months of ownership and 19144 miles! 90 mile daily round trip commute with no office charging, plus a bunch of trips to San Diego (200 mile round trip) and a few Santa Barbara (300 mile round trip), and one drive to SF (900 mile round trip) and Vegas (500 miles round trip), so I'll never break record MPGe. Tires: Yokohama Avid S33 (recently started using 40/38 PSI, but was 35/33 PSI most of the way) Breakdown for the technical folk: 19144 miles 3024 miles EV (15%) and 16119 miles HV (85%) 272.46 gallons at the pump (259 gallons estimated by car) at an average of $3.68/gal, total of $1003.33 using majority Costco Gas 608 kWh (measured by the car) at approximately $0.175/kWh (Southern California Edison Tier 3 every month), total about $106.40 59.2 MPG in HV mode and 4.97 Miles per kWh (not accounting for charge loss) in EV mode Total Spent on Driving thus far: $1109.73, or about $0.058/mile
Thanks! Costco gas prices are significantly more reasonable than most, and my area tends to have better prices. Gas prices have been low for the most part this year. I filled up at $3.339/gal today!
that's excellent. they just opened a costco station here, was $3.10 a week ago, maybe lower now. do you get a % back on gas purchases?
Yup it's 3%. But it was obviously more $$$ when I had my Mustang lol. I guess that's about one free tank for this year now.
i know, it's gonna take a lot more than cheap gas to get me into costco at 50 gallons a year. i'll have to look into the amex connection, that might work. problem is, i get my wine at bj's and that saves me way more than the membership cost.
My Costco Executive Membership is nearly paid for by the rebates from shopping there alone. This is for two people, basic household needs and foodstuffs and every few years a major item like a computer. Add in the Costco Amex Card rewards, (4% on gas for me since I've had the card a while) and it becomes a winner for us. And now Costco has Top Tier spec gas to boot. Yes, Costco sells things in quantity, but if you can make room to store staples such as paper goods, toiletries, etc, you can save money.
I filled up today at Costco...my car said I had 2 miles left on gas mode...the bill was around 28 dollars not bad.
