Do Tires Matter? You bet.

The tires that come with your hybrid are designed to giving you the best fuel economy.

I found out the hard way. When the original tires provided with the Prius, Goodyear Integrity, wore out, I changed to Michelin Harmony.

The first thing I noticed was a drop in fuel economy [about 5 mpg Cdn in city driving]. The tires seemed to wear a lot slower than the Goodyears, but the loss of the fuel economy and the premium of $20.00 per/ tire does not make good "cents".

In the future, I’ll just be put on the manufacturer’s original tire selection when it comes time to replace them.

Andrew Grant is the world’s first hybrid taxi driver. He introduced his Prius taxi to the not-so-mean streets of Vancouver in 2000, and logged 200,000 miles in just 25 months. Andrew’s Prius was snatched by Toyota. The automaker wanted a chance to study the durability of the hybrid batteries and other components, which held up amazingly well. See this video for details. He’s now driving his third Prius. Andrew has taken a break from taxi-driving, and now works as a professional coach helping his clients achieve personal excellence in various fields of endeavor.

    But Cheyenne, I work in the ‘burbs. Where should I live–generally speaking?

    One reason I like my car is the security. I travel alone or with people I trust. But on a train, the kid in the next car could be a bomber intent on killing as many as possible by striking mass transit.

    I am all for changing car design to match actual use, one or two people are in the vast majority of cars I see on the freeway. So why are their no big and roomy two seaters weighing 2500 lbs and getting 50 MPG? The second car, the work car needs to be available.

    Just thought I’d let you know I’ve just switched to Michelin Energy tires and my mileage has perhaps gone up a bit. My current tank at 330mi is 55.9 mpg.

    For the premium price of the Michelin Energy tires compared to the Goodyear Integrity, I think what little extra fuel economy you recieve won’t justify the extra cost. Plus the Michelin Energy has the same tread life expectancy as the Goodyear Integrity.

    Is it the tire so much as to how much you inflated it?

    ’04 civic hybird: I keep my Michelins inflated to 35psi. I get ~50-55 mpg @ 60-65mph. I had to replace my OEs at ~25K because they vibrates & made a lot of noise.

    I’m happy with Goodyear Integritys on my Prius. I’m trying to save gas and improve MPG, not qualify for the Indy 500 or improve handling at high speeds.

    When I got caught in last year’s first rainstorm, I hydoplaned all over the place. The anti skid computer came on all the time. I had to slow down to 50 MPH. I changed to Michelin “T” rating tires. Cross wind unstability and hydroplaneing both eliminated. At first I lost about 2 MPG, but I inflated the tires to 35 PSI and now I am actually better than before. Last 400 mile run, 70 MPH freeway only, 51.1 MPG.

    Going in for the 60,000 service next week. Only comment is the vibration of engine shutdown when you are stopped at a light of intersection. I going to request new engine mounts be installed. No other issues. 2004 Prius Plan 9 car delivered in March of 2004.

    A bit more expanding on my Sept 21st email. The reason I switched from the Goodyear Integrity to the Michelin Energy series is as follows: I drive 53 miles one-way to work. Here in Colorado it snows frequently in the winter, and the Michelin was rated much higher in handling characteristics.
    Now that I’ve got a few miles on these tires, I can say that on dry roads, the Integrity is just as good, if not better than the Michelin, and perhaps a little better in some instances, because the Michelin has the nasty little habit of following those grooves that are put into the highway to make traction better. Still getting over 50 mpg, though so can’t complain there. Will have to wait and get snow before I find out how the Mich. track on slick surfaces.

    I see your reason for buying the Michelin Energy series, for the potential improvements in winter driving. I agree if you can get by without having to put on a seperate set of winter tires thats great. Myself I have a seperate set of Bridgestone Blizzak for winter driving myself, I don’t get anywhere near the amount of snow as you do in Colorado.

    Let me know how they perform.
