Low Rolling Resistance replacement tires: Current List

QUOTE="phigir, post: 2130441, member: 71269"]I have a 2010 Prius IV in need of new tires. I have searched through many pages of this post and it seems the Michelin Energy Saver a/s are the way to go. I currently have the original 195 65 15's. I really want a nice quiet ride, without losing mpg. I also live in Palm Springs CA where our temps are well over 100 for 5 months out of the year. Is there a better tire for my driving conditions? Please keep in mind I still would like to keep the ride quiet. Thanks for any suggestions.[/QUOTE]
OEM tires are perfect for many climates. Run 40-42 PSI (44 for a heavy load) in your tires and have at least one alignment in 50,000.
At 44K my tires have most of the original tread left and were perfect with no factory defects. Kept them for spares.

The 20's have been the best all around tire for the Prius for a tire that consistently gets the best MPG. You should easily get 80K out of these tires if you do the above. If you run them at 32 PSI do not expect miracles. Most tire shops put 32PSI in tires and push it out the door. SAMS has been the best on doing what I asked and the dealer needs follow through and over sight. Don't leave any shop without you checking the fluids and tires pressure as well as looking under the car.
IMHO///Always buy a MIJ OEM as that has been the best for my 7 hybrids over the years. For non-hybrids get the best Michelin you can afford. The Goodyear LRR tires are a good second if you can't find a Michelin at Sams.

 

Funny, I can remember getting tires for our trusty Accord, back a few decades. I'd get home, see they'd air'd them up to around 32, and 'cause the sticker in the car door said something like 28, I'd bleed air out of them, lol.

 

Air heads,weren't we!!! H

 

They use to teach that in the auto technology courses. 32 out the door, 4 quarts and check the dip stick except for large trucks and buses.

BTW, got a full set of 20s on my 2011 yesterday. Walmart at first refused to put my new tires on and then relented. Walmart said they were in too good of a condition at 50k. So then Walmart said they had to put 33PSI in all the tires. I said the dealer will put 42 in them so what is the problem. Then I said you can go up for heavy loads and high speeds and Walmart said that does not apply to cars.

 

Costco is the same on tire pressures. They'll lecture you on the subject.

 

Well I misread the posts & got the wrong tires yesterday.

I bought a set of Goodyear Assurance Fuel Max tires. I meant to buy a set of Michelin Energy Savers instead.

Anyone driven a set of each of these? Your experiences? Which one would prefer?

Seems like the Goodyear set makes the driving very floating when changing lanes vs. the stock tires.

Im in south texas so dont have to worry about ice/snow.

Thanks

 

You will be happy with the GY Assurance fuel Maxx. They are a good tire. If you made a mistake, maybe they will exchange them with what you wanted. Tell them you don't like what they installed. I had a set on my HCH2 and they gave me excellent FE. Hal

 

Actually if they are as good as the MIJ OEM ones your fuel economy should be great. Just got rid of mine at 50K since my wife was complaining about the noise. Most of the tread was still there.

 

I will be getting a 2010 Prius V. I've read through the last few pages of this thread and determined it's best to go narrow with the 205/50R17 and it looks like the EP422 or the P7 A/S+. I already have dedicated snow tires. What kind of mileage can I expect from the 17" rims? I have the Michelin Energy Saver A/S on my 2010 II and easily get 54 MPG. Nice quiet tire too. Thanks

 

We've got Canadian Touring model, similar to US V, has the 17" rims. Our OEM's are 215/45R17 Michrlin Pilot. In winter I put on 195/65R15 Michelin XIce2 (on steel Corolla rims).

As far as I can see: the mpg doesn't skip a beat at the transition, ones on par with the other.

 

I've got almost 59,000 miles over 60 months of driving on my original equipment Yokohama Avid S33D... last March I was advised not to buy new tires even after having to repair 3 of 4 of my tires because of road hazards because the car tech said my tires had too much tread left but by last Fall I was being advised that it is time to change my tires. because the sidewalls on the tires are starting to go bad. Given the bad weather I didn't want to switch tires right away(it's easier to prep tires in the spring time). I'm living in the Washington DC area - what kind of tires do you think I should I get? A while back I was reading that Michelin All Season Energy Savers was the tire to get but I'm wondering if that's still the one to get?

 

Glad to hear that someone has successfully tried the narrower section tires with upgraded wheels with minimal impact on FE. If I upgrade to 16s or 17s, I will definitely go with 195 or 205 section tires, respectively. Do you have pictures of the 205 tires mounted to your 17" wheels?

 

Kyle, sorry for any confusion. I do not yet have the 2010 Prius V with 17" OEM wheels. I'm picking it up this weekend. The V has mismatched tires. Yoko Envigor 215/45R17 on the back and some no name tire called "Goodride" on the front in the same size. The tires are in new condition. I will be replacing them with a matched pair at some point and I will be taking your advice of the 205/50R17 in the EP422 or the P7. I do also have a Prius II with the Energy Saver A/S 195/65R15. I can consistently get 54 MPG with those tires. I was curious as to what to expect for FE with the 17" wheels on the V.

 

I commute almost 1000 miles a week to work and back. I hypermile and get usually close 55 mpg in winter and right around 60 mpg in summer, with 25% of this being city driving with a dozen plus stop and go traffic lights. This is on old, worn, weather cracked, non LRR tires. Due to the weather cracking I have been afraid to go over 37-38 PSI.

It is time to get some new tires.... I have been searching for the best price online. Of course I plan on going with the Michelin Energy Saver A/S and push them up to around 42-43 PSI to see how much I can improve my MPG.

The big questions is: I notice there are two different Michelin Energy Saver A/S listed and there tends to be about $10 difference between the two.

In the OP are you referring to the 88H or the 86T load/speed rated model of the energy saver A/S's?

Will it make any difference in MPG, depending on which ones I choose (I.E. does one have a harder tire compound or is one "lighter weight" than the other, etc....)?

Any and all input is appreciated.

Thanks,
Paul

 

Great question! I bought the wrong ones several years ago due to not reading the exact model in the post. Big MPG drop. I was tempted to get these but stayed with the EP20s MIJ from Walmart online.

 

So new question!

I filled up at the BX this week and it took 9 gallons with one PIP. Is this about right? Also the MPG went up dramatically, as I was driving, over the SAMS Club gas fill up in the past. You think I got premium out of a regular gas storage tank or the gas blend is different?

 

I filled up yesterday at WAWA. Just for fun, I put in non-ethonal 89 octane. On the way home I had the cruise set at 77MPH for almost 50 miles. The car flashed 51.4mpg for the trip. It's usually around 48mpg for the same trip with standard 87...

Not worth the extra $.30 per gallon over time, but it was fun to see the difference ethanol vs. non-ethanol makes.

 

Due to the snow and ice I had lost a wheel weight or two and rear of car has a shimmy. I didn't want to pay to have tires balanced when I needed new tires anyway. I ended up going with the 11xx load capacity ones (86T I think but don't have info in front of me right now). I finally found a site that listed the tires actual weights. It's funny that this info isn't more readily available on tire sites. I looked at dozens of sites and only found one that listed actual tire weight. One was listed at 17 pounds per tire and the other 18 pounds per tire. So I chose the 17 pound model. Pretty sure I made the right decision.... hopefully lol.

OEM MIJ

Tire rack is very accurate on specs. The OEM MIJ EP20 is #19 and the newer one is 17-18. I have no idea what the difference is for those two Bridgestone.

 

Just bought the Pirelli P7 A/S+ P205/50R17 with a $60 mail in rebate at Discount Tire. I'll post pics when they are installed and let you know about the MPG.
