Just purchased Bridgestone EP422 tires

My Michelin Energy Saver AS tires, 195x65x15, with 68,000
miles were just about down to the wear bar indicators.

So I went to Costco and had them install Bridgestone EP422 tires
195x65x15, all with 44 PSI max sidewall pressure. Costco
has a special $100.00 off for a set of 4 Bridgestone tires.

Price out the door was $371.00, the Energy Saver Tires 3 years ago
were $465.00 out the door. (Note: No sales tax in Oregon).

Drove home from Costco and these tires are quiet and roll very
nicely, and I am pretty sure I will obtain the same mpg's
as the Energy Saver tires. Indicated MPG's, I filled up at
Costco and reset Trip B, when I arrived
home was 58 mpg or about 54.5 or so true.

 

I will keep you posted on these tires just like I had with
the energy saver tires....

 

Update: have about 150 miles or so on these tires. My wife has been driving
the car about 75% of the time and she does not drive for fuel economy.

The indicated MPG gauge is 53.1, I believe normally with the Michelin Energy tires
with my wife mainly driving the gauge would probably read about 54-56 mpg or so.

Now these are brand new tires so I would imagine they are breaking in
and probably after a few hundred miles we should be obtaining the same mpg's
as the Michelin tires.

Also these tires appear to be little taller than the Michelin Energy tires.

They are quiet and roll very smoothly and at this point I am satisfied.

I have a 30 day money back guarantee on these tires and if they do
no perform up to the standards as the Michelin I will exchange them
for something else, maybe another set of Energy Saver tires.

I will be on vacation the end of this month and that will be
the true test after a 1,000 mile plus road trip....

 

Update: 354.4 miles / indicated mpg 53.5 / calculated 51 mpg /
My wife mostly drove, looks like a loss right now of about 2 or maybe 3 mpg
over the energy saver tires which had 68,000 miles on them.

I am pretty sure they will get better mpg's as they wear in a little.

 

44 psi in all four tires, this is maximum sidewall pressure listed on
the tires.

 

Update:
146.4 miles / 50.605 mpg calculated
We now have over 500 miles on these tires. When I filled up at
Costco I reset the trip meter and upon return home, 11 miles the
indicated mpg's was 65 mpg. Pretty close to what I would normally
get on the Energy Savers.

I am pretty sure they will get more mpg's as they wear in a little more.

 

The original tires when new were Yokohama Avid. I believe that
was the factory installed standard tire for the 2010 Prius model.
