In Australia Prius come fitted with Michelin Energy tyres, size 195 60R 15. These use silica compound in the tread to improve tyre life and grip. Silica also improves rolling resistance improving mileage. Sorry I can't report on wear as I have only had my Prius a few weeks. I did notice another Prius I test drove which had Goodyear tyres on it didn't seem as responsive and had higher consumption on the information display but this may have been pressure or an unrelated matter. Then again my Prius was supplied with only 32psi in the Michelin tyres.

Michelin have Hydroedge in USA which is a silica compound tyre with low rolling resistance.

According to the chart it looks like the Sumitom HTR200 has a better LRR and are even cheaper in price and have more traction and better wear rating
For $36.00 a tire that is LRR that seems to be a great price even the Goodyear for 46.00
The only thing the Sumitomo HTR200 Is better suited for NON-FREEZING areas no snow or Ice It is their summer tire

When I need tire I will look them up.
thanks for the link

 

I was quite disgusted with the standard tires for my 2001 Prius; I was replacing them every year or 12-15,000 miles. So I took advice I found here and elsewhere and purchased Michelin Harmony tires. Purchased online (Tire Rack) for the same price as the standard Bridgestone Potenzas, had them shipped to an installer, and then took a 2000 mile road trip. I was warned that gas mileage would decrease with new tires, and expecially with tires that have a higher rolling resistance. But gas mileage decreased only 1-2 mpg over the several thousand miles. The loss in mileage is way worth it...just think of the money saved and lessened environmental impact by having tires that won't ear out in a year. YAH!

The current generation Prius DO NOT come from the factory with LRR tires. Of course, you could always switch to them, but you will do so with reduced handling.

 

Im so confused...which tires should i use? A specific number would be great.

 

WOW that is a surprise. My 2010 came with Yokhamma LRR tires and I've seen a few on dealer lots with either Yokahamma or Goodyear Fuel Max tires, but I haven't looked in awhile. What do the 2012 Prius come with for tires?

 

You need to do more research. I suggest you first read the list of LRR tires that F8L maintains. It should be easy to find using the search function of PriusChat.

 

That is an incorrect statement. All Prii come with LRR tires. The OE tires are designed to Toyota specs, not the specs of the manufacturer of the tire. Thus even though a specific model may not be listed as LRR by the manufacturer, rest assured that the OE version is LRR.

 

factory yokahama the same that came with the car..yoka 322 lrr

 

michelin e/s.

 

The factory tire is a Yokohama S33D, Bridgestone Ecopia EP20 or Goodyear Assurance Fuel Max. all are 195/65/15. The Model V (Five) comes with a Toyo Proxes A20 215/45/17 and the Performance Plus Package comes with a Michelin Primacy MXM4 215/45/17.

 

i put on theLLR ecopia's but got horrible mileage "39" and, the Toyota dealer said he never seen ecopia tires on a prius. because of those reasons , I had my tire guy pull off the ecopia's and replace with yokahama's the very next day. still not getting 50mpg.. starting to piss me off.I'm averaging 45 on day 1. will my mileage get better after breaking in tires??

 

That's a load of crock. The dealer is full of it.

The Ecopia EP20 is standard equipment on 2010-2013 Prii. They are a fuel efficient tire. Your problem with fuel economy is due to

1. putting on a new tire. All new tires have higher rolling resistance than a worn tire of the same make and model. Tire Tech Information - Tire Rolling Resistance Part 3: Changes to Expect When Switching from Worn-Out to New Tires

2. Dropping down to 39mpg from 50mpg is more than would happen just froma tire swap. You need to consider environmental conditions before jumping to conclusions.

Furthermore, tires require a break in period before you will achieve optimum performance. This can be as much as 2000 miles. A single day is not going to tell you anything unless you are well versed in tire tech and fuel efficiency.

The Yokohama tires are not 27.6" in diameter. They are 25" in diameter with a revs per mile of 829. There is no way you can make a 195/65/15 be 27.6" in diameter unless you mount them on the back of a 4,000HP dragster and do a massive burnout.

 

I bought at Costco in Sequim WA Bridgestone tires on the recommendation of the sales person for my 2005 Prius. Somebody in PT Townsend had done research on many tire brands and found that the Bridgestone tires that Costco were selling was one of the best for rolling. Before the new tires I was getting about 47 miles to the gallon, now I'm getting 53 Miles per gallon or better. I am impressed.
