Tire Rack pits Integrity against Energy Saver, Ecopia and Fuel Max

FYI,
The EP20 is all season tires, while the EP100 is summer tires.
The Japanese 2010 Prius 15inch version comes with the EP25 OE summer tires.

I would rather have an AST...be nice if Bridgestone's site mentioned

it would be neat to see how long the tires last and take that in account some how. The michelin's get the best mpg but the also only have 9/32 tread depth.

According to Michelin's website, the Energy Saver will last 15k miles longer than the competition. I assume this means Ecopia and FuelMax

Depends on the definition of "lasting." Their Michelin OEM tires that came on my Toyota Avalon "lasted" until I got so tired of taking them in to be plugged for leaks (fast and slow which often took two or three tries to find) that I dumped them at about 30,000 miles for Toyos. The Toyota sales manager (in Nampa, ID) recommended them (and that I go a size larger) and it was a big improvement. Not sure how long the tires would have lasted but never had another leak during the second 30,000 miles (when I sold the car because I wanted an AWD vehicle (current CRV).

by lasting i mean till they hit 2/32nds. I know a good amount tires dont get this far due many reasons but lets just say they do. so if u assume that the tire tread will last till they hit the warranty and your main concern is money saved, wouldn't you want to get a tire with the highest tread warranty.

I will put some numbers together and see what comes out, I think you would have to see a pretty big hit in mpg with the higher tread life tire or a big gain with the energy saver/fuel max tires.

This also probobly relates to how u drive as well, so this may be a wasted effort. If your a super hypermiller maybe the new tires are better for u.

OK call me stupid because I have been wondering about going to thinner tires to reduce rolling resistance, but as one person pointed out, the load capacity just isn't there with thinner tires.
According to Tire Rack and if remember correctly, my tire width is 195, but the tires tested were 185's?

Appearantly you have the Touring Pkg.?
If so, you won't find a 185 in a 16" tire. That (16") is a more performance oriented size, not economy. Touring Prius' have never gotten the gas mileage that Std Prius does, because of the tire type/size.

These new LRR tires are oriented toward economy sizes, not performance.

You could always replace your wheels with STD Prius wheels.

The Bridgestone EP100 comes in your size but it is a summer "performance' tire that toughts some LRR qualities. Not quite the ultra LRR of Michelin

Bringing this thread back to let everyone know that tirerack.com has an EXCELLENT price on the EP20. I hit a curb (avoiding an overzealous trick-or-treater) and had sidewall damage to one of my tires. The local Firestone TOLD me they had the tire I needed, but when I got there they tried to mount an EP100 on the rim (completely different tread pattern). They told me it would take several days to get an EP20 and it would cost $137. I went home and ordered an EP20 from tirerack.com for only $85 and it arrived two days later. Tire Rack FTW.

According to Tire Rack's test protocol
When Round and Black Becomes Lean and Green
all tyres were set to 35 psi front, 33 rear. I didn't check each tyre spec to see if recommended max psi are the same, but if not I am skeptical about the results.
