Prius Tire Upgrades

<div class='quotetop'>QUOTE(theorist @ Oct 22 2006, 06:53 PM) [snapback]336535[/snapback]</div>

195/60R15 is the OEM size for the Prius in Australia. It causes less speedo/odo distortion than the 195/65R15 since revolutions per mile are .9% higher, versus 2.2% lower. Also, for nearly all brands, the 195/60 will have wider tread than the 195/65 since there is less balloning with a lower tire. Therefore, the 195/60 will handle better than the 195/65 because it has wider road surface contact and the car is slightly lower than the OEM 185/65 versus slightly higher for the 195/65.

 

My Prius is come with the size 195/55-16 tires on 16" rims. I have changed it with Goodyear Excellence 195/55-16R and changed the rims to Enkei RS+M 16x7.

 

Hi;
I just bought Prius 2008 Pkg. 2 Dark Blue. I was thinking upgrading both the tires and rims. And this is what I have in mind.

205/50/17 Michelin Pilot Exalto A/S with Enkei RS+M 17.
Please let me know what you think and any recommendations you may have.

Cheers.

 

For new cars, you can do a new tire swap of the 185/65 Integritys with Goodyear for wider tires--195/60 Comforttreads or Tripletreads. I've done it before with other cars.
The Comforts are quieter, the Triplethread are better in wet/snow conditions. A tradeoff. Both are rated much higher than Integrity on Tirerack. They also cost more.
$81 for Comfort, $97 for Triple vs $65 for Integrity. Is it worth it? Maybe in winter climates.

 

I checked with a local Goodyear dealer, and they will swap the same tire size only--since 185/65 is the only Prius spec size for 15" wheels. The ComfortTread in the same size will cost $25 added plus install per tire.. More of a premium tire than the Integrity. Better traction, wear and lower noise. They currently have a $40 rebate so I'm considering it.

 

Interesting info. I don't suppose Bridgestone has an equivalent deal ? In Canada ?

 

You seem to know a lot about Tires.. I have the 2010 model V with the 17 inch rims. My Firestone/Bridgestone guy recommended the Potenza Re960as Pole Position. Any thoughts about if there is any tire that would give me better mileage than my OEM tires?

Any thoughts about the best winter tires?

Any Prius owners our there who use a snow tire?

 

i'm currently on 19 Inch Falken FK-452 Tires - 215/35/19 all around.

44psi in Front and 42psi in Rear.

i'm liking it so far...~ !

 

You must be taking a huge mileage hit as well as a rough ride. I have 17 inch Scion TC rims with Bridgestone Potenza EL400 215 45 17's and am taking a 5MPG hit. Any tire upgrade suggestions to improve mileage? I know the wheels itself are 8lbs heavier than OEM which hurts.

 

i'm averaging 559 miles for a full tank of gas at the moment.... not sure if that's good or bad for riding on 19"s and pure city driving....

 

for all season use, I'm running Goodyear TripleTread FuelMax US OEM size on my 07. I haven't done any calcs on mileage, but the ride seems ok.

 

I switched to the GoodYear Assurance FuelMax tires 7000 miles ago. Since then, I have noticed a 3-5 MPG increase over the Integrities and a much quieter ride. They come at 51 PSI max and I have them at that pressure. I changed the integrities at 61,000 miles. So far the FuelMax tires show almost no wear after 7000 miles.

 

I have a 07 Prius and I switched out the tires as soon as I bought the car with the RE960 PP. I live in Ohio and drive them year round, they perform quite nicely in snow unless it gets really deep. Average 2 to 4 inch snow no problem and I have a steep drive that I don't shovel. This tire is real good quiet, handles well and has real good tread life for me so far. I currently have 13000 miles on them and they have only worn about 2/32. I suspect I took a MPG hit of about 1 or 1.5 MPG, but I get up to 52 MPG on the highway and I have removed the wheel covers so the too could be contributing to my MPG decrease.

I have a 2010 IV SR on order now for 3 months and I will be ordering a set of RE960 PP for it and will put them on as soon as I take delivery. Now I think I will stick with the 15" wheel size or possibly 16 but i am getting new aftermarket wheels for the 2010 either way.

Anyone interested in a set of 15" wheels or tires or both let me know, as they are coming off my 2010 as soon as I get it. The TPMS sensors will not be included though.

 

My Intregrities were pretty much worn out after 24K, and replaced them this week with a set of OEM size GoodYear Assurance FuelMax tires. I got about a 45% cost savings from GY on a warranty adjustment, plus a small rebate.
The FuelMax has better ratings than the Intregrities, but not as good as the ComfortTred. I elected to go for the better mpg, rather than comfort and quiet. Time will tell how the FuelMax will do, but I should get longer service life.

 

I have a 2007 Touring with 16" wheels. I replaced the original equipment with Michelin Pilot Exalto A/S. Mileage went down by 2 miles per gallon and after 15K miles they be came very noisy. Michelin refunded me $95 per tire. I have always used Michelin on all my vehicles and will still continue on my other vehicles. However I bought 4 new Bridgestone Ecopia EP100's and my mileage went up 4 miles per gallon. Tires are quiet and have a 50K plus mileage rating. I now have 70K miles on my Prius. Great tire for Prius Touring models.

 

Just put a new set of Yokohama Avid TRS, 195 60 15, on my 04 Prius. I had replaced the OEMs, which were absolutely useless, with Toyo Spectrums after a couple of thousand miles. The Toyos were fine, no problems and wore very evenly.
