The Ecopia EP422 is one of Bridgestone's ecologically oriented Grand Touring All-Season tires developed for the drivers of coupes, sedans, minivans and small crossover vehicles looking to combine year-round traction, handling and comfort with reduced environmental impact. Ecopia EP422 tires are designed to enhance vehicle fuel economy by reducing tire rolling resistance along with the vehicle's carbon dioxide (CO2) emissions while delivering year-round, all-season traction, even in light snow.

The Ecopia EP422 uses an all-season tread compound featuring Bridgestone's unique NanoPro-Tech (Nanostructure-Oriented Properties Control Technology) to reduce rolling resistance and energy loss while maintaining dry, wet and wintertime traction.

This compound is molded into a symmetric tread design that combines notched shoulders and intermediate ribs with independent center blocks for dry road tracking and traction. Four circumferential grooves are designed to help water flow from under the footprint to resist hydroplaning and enhance wet traction while notches and sipes increase the edges that bite into light snow. The tire sidewalls feature Bridgestone's Fuel Saver compound to further increase efficiency.

The tire's internal structure includes twin steel belts reinforced by spirally wrapped nylon on top of a polyester casing to blend ride comfort and durability.

*Specific sizes featuring Ecopia technology are identified as such on the Sizes tab, as well as on the tire's SPEC tab.

Customers Say

Customer surveys indicate the Bridgestone Ecopia EP422 excels in comfort with many ratings in the 9-10 range, praised for smooth, quiet rides. Treadwear receives strong praise for longevity in most cases, though some note rapid wear concerns. Winter traction stands out as a weakness, with inconsistent scores (3-6 range) highlighting limitations in snow and ice. Wet traction impresses with reliable hydroplaning resistance (7-10 scores), while dry traction consistently earns top marks (9-10) for confident handling. As a grand touring all-season tire, it delivers strong year-round performance outside harsh winter conditions, with comfort and dry/wet capabilities being standout features.

...In heavy storms this past weekend the tires were solid, no hydroplaning, excellent grip with a fast stop, and no slipping on fast, wet starts...

I replaced a set of Bridgestone Turanza w/Serenity with 35k miles which may have had a bad belt. I bought the Ecopia for the high treadwear rating and 60k warranty. After 6 weeks in dry & wet driving these tires are excellent. Handling is super, quiet, & smooth. In heavy storms this past weekend the tires were solid, no hydroplaning, excellent grip with a fast stop, and no slipping on fast , wet starts. I could not be more pleased with these tires.

...Better traction, especially in wet conditions, and very quiet.

Purchased the car at 120,000... now has 140,000. Have had the EP422s on for the last 5,000 miles. Much improved over the Integrity tires that came with the car. Better traction, especially in wet conditions, and very quiet.

Now when I rated this tire as a 8 in wet traction... I'm taking into consideration that this is relatively small tire, and comparing it to other tires I have driven of a similar size. In my case I'm not driving a sports car so I don't expect it to handle like a sports car.

Also (very important) we experienced no change in fuel mileage. This was a big concern for us. We drive a mix of highway / country roads for the daily transit and consistently get 43 - 45 MPG. (before and after the EP422s)

I considered other tires that would have had more traction, but I was very concerned about losing MPG... I felt we should get a LRR tire. I think we made the right choice, and we are very happy with the purchase.

Summary: Would recommend to other Prius owners and would purchase again.

...Great dry traction and wet...

I have 103,000 miles on my 2008 Prius. This is the third set of tires and by far the best. The initial OEM tires needed to be replaced at 28 K. The next set were extremely loud and dropped my mpg about 15 %. Switched to the Bridgestone's and have loved them since. Great dry traction and wet. I don't drive my Prius in the snow so no experience there. Getting ready to buy a new set.

...They even performed better on corners and felt more responsive compared to the Dunlop OEMs, but still won't blow you away...

After about 1000 miles, these tires have definitely exceeded expectations, they are much, much quieter and ride comfort has increased a good amount compared to the OEM tires on my Accord (Dunlop SP 7000). They even performed better on corners and felt more responsive compared to the Dunlop OEMs, but still won't blow you away. Gas mileage seems to has increased about 1MPG but the ride comfort/noise level is what made these tires worth it.

...Other than LRR, the most noteworthy characteristics (to me, anyway) of the tires in their first 900 miles of use have been the fine ride quality and low levels of noise.

The Ecopia EP422 is an excellent grand touring tire with low rolling resistance. It's particularly well suited to cars like the Toyota Camry that aren't overtly sporty. Other than LRR, the most noteworthy characteristics (to me, anyway) of the tires in their first 900 miles of use have been the fine ride quality and low levels of noise.

The ride feels smoother than the previous/factory tires...

The tires felt a little "floaty" when first installed but after a short time have broken in and performed great. I have driven in fairly heavy rain and had no issues. The ride feels smoother than the previous/factory tires. These are the new tire for my car unless they don't wear good over time; so far so good.

I have 65K miles on these tires and they will easily outlast the 70K mile warranty. They get great gas mileage, last along time and do well on traction. They aren't high performance sport tires so if you want cornering speed try a performance tire. If you want a tire that performs very well, last a long time and get good gas mileage these please consider these tires.

...I also put these tires on a 2009 Sion xB, and the wear on both cars has been excellent. I have the tires rotated and alignment checked every oil change...

This is my third review of these tires. As with the previous reviews, I would give these tires a 9.5/10 on all counts. Quiet, smooth, brakes well on dry and wet surfaces, cornering good given the size and suspension of the car. Unfortunately, hardly any snow this winter, but what we had, the tires were great. I also put these tires on a 2009 Sion xB, and the wear on both cars has been excellent. I have the tires rotated and alignment checked every oil change. I highly recommend the Ecopia tires.

Winter traction shows concerning scores between 0-6. Many customers report slippery in snow, loss of traction, and being stuck. Despite being all-season, some found winter performance unacceptable with complaints of sketchy handling on ice.

...However I really dislike these tires during snow and winter conditions. I am an experienced driver in winter conditions, the Subaru is AWD and still I feel the car sliding and loosing grip often in snowy. I am not sure if its the tread pattern, rubber compound or design...

I have a real love / hate relationship with these tires. I love the handling and responsiveness in most conditions. Very quietI think if I lived in the south I would rate these Ecopias a "10" across the board. However I really dislike these tires during snow and winter conditions. I am an experienced driver in winter conditions, the Subaru is AWD and still I feel the car sliding and loosing grip often in snowy. I am not sure if its the tread pattern, rubber compound or design.
Tread life seems very good so I have no need to replace them.

...They break traction on wet roads when pushed only slightly. I have absolutly no confidence in them...

The tires were O.E. on my new 2016 VW Golf Sportwagon. When I purchased the car I immediately got larger wheels and summer performance tires, purchased from Tire Rack, which I installed immediately . I swapped them back to the O.E. all-season Bridgestones in early Nov. with the arrival of colder weather. What a huge change for the worse! After driving about 1,000 for a month my patience wore out. They break traction on wet roads when pushed only slightly. I have absolutly no confidence in them. The steering response is poor. They are noisy. I purchased a set of Pirelli winter tires and wheels and the car feels like it handles well again. I know that it seems somewhat unfair to compare them to performance tires, but the Bridgestones were just terrible.
