Michelin Energy Saver A/S Review

I'm not sure if we can safely assume the mpg will increase in a nice linear fashion as tread wears down. Any tire will increase in efficiency as the tread wears down so if much of the LRR characteristics of a specific tire is in the tread then as that tread wears out it will become more similar to lesser tires. That is the theory anyway. Given the Energy Saver A/S provides a mpg boost when new even compared to well worn tires I suspect they will always lead in efficiency, even when worn.

I still cannot believe Michelin is going to stop producing them. I need to give them a call and confirm/complain if this is the case. This is the only tire I have ran that allows you to drive like the average Joe and still pull down high mpg numbers. Maybe it's too much of a niche tire?

Oh, I forgot to add that the out of balance feeling is still here even at lower pressure. I'm going to bring it back to the shop and have them check it put.

i would like to know why they are discontinuing. if you talk to them justin, let us know if you think it would help in any way for a mass email to perhaps change their mind.

I shall!

Yes, please let us know. If they discontinue the tire hopefully they'll come out with an alternative that's the same or provides similar benefits. I was planning on getting this tire when my OEMs ran out...

I guess I didn't know this. So in theory I should eventually see better mpg the longer I run my OEM's?

Yes. Mainly because there is less tread to distort and waste energy but also because the tire is becoming smaller which could fool you into thinking you are traveling faster than you really are. The last part is more jest than true.

The largest gain from reduced tread occurs within the first 50% of wear. After that the gain rate is reduced but you will continue to see improvement.

You guys that order from Tire rack, what do you do have them shipped to your home, then pay someone to put them on? I was thinking of doing this, can't get local dealer to get them for me.

Luluz

I've got nearly 51,000 miles on my Avid's and they were at 3/32 and 2/32 (had I done my tire rotation at 45,000 miles, they may have both been 3/32). But, it appears that the Michelin Energy Saver A/S tire is going away in the P195/65/15" size (Gen III prius size) so I opted to get a set now rather than run my tires for the last 5K life left in them.

Good luck!

Just thought I would share my downhill evening commute from Auburn to Davis instead of Woodland.

85.4 mpg over 47 miles. Pic soon to come

The mileage will be even better once you drain the 12,000 mile old tar oil out of your engine.

It hold sentimental value....

As does a seized, sludged up engine.

Then this may amuse you:


Downhill too, but only about 500 feet spread over the 50+ miles. Stock 15" Goodyear Assurances @ 44/44 psi.

Not amusing.

What was your speed? I had to stick to 60mph most of the way until I got back off the freeway. I could tell I was annoying people. lol

Regardless, the stock AVID S33Ds couldn't do this so I can only imagine what you would get with different tires that are not worn down. Mine were installed earlier this week.

I was shooting for 50mph on the highway, but average was 40mph due to several tollbooths and lower limits through Boston and on surface streets at the end of the trip. Nobody seemed annoyed, no tailgating or horn honking.

I guess the 1:00 on your display means that your 47 mile trip took an hour, which would mean 47mph? Faster than me. Perhaps you had more downhill?

Amusing that we went about the same distance at the same mpg.

I stuck to 60mph cruising speed most of the way but in a few places the traffic slowed down for an accident or traffic diversions for freeway repairs. The avg speed dropped quite a bit when I hit the 3 miles of surface streets. I was happy to get off the freeway! I decided to test how using CC would affect my morning commute and it dropped my average by about 1.5mpg so I was trying to make up for it. I am sitting at 66.?mpg right now.

I'm still happy to even come close to numbers like you get.

Justin - You're going to have to start a new fuelly car for your Prius with your new tires. You'll catapult to the far right of the bell curve! LOL!

Those early tanks drug me down quite a bit. Honestly though, if I started all over again I'm sure it would look much different. All this testing has made for a pretty weak Fuelly sig. I'd kinda feel like cheating if I started over. Hmmm lol

You have my vote to start a new one!

I see you keep your pressures at 44/44 instead of something like 44 front and 42 back. Why don't we all do this? Wouldn't it possibly yeild better mileage numbers? I know the additional 2 PSI difference in the front is usually due to the weight of the engine but what's the harm in having them all at the same PSI?
