The Ecopia EP422 Plus featuring T-speed rated sizes is one of Bridgestone’s ecologically oriented Standard 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.


  1. Tires are great I’m going to be getting them again these came on the car brand new and after two and a half years and 61,000 miles I still have 4/32 of tread left on the outside edge. Hands down great Tire get between 55 and 62 miles to the gallon with these tires on my Prius

  2. These tires are probably at the top of my “good deal “ list. They’re quiet, show almost no wear after a year and air loss is negligible. I’m very happy with them and would buy another set without hesitation.

  3. These tires are not particularly good at anything, but the road noise is what I find mostly offensive. It always bugged me, but when I purchased a new pair of Continental WinterContact tires for the winter season, I was amazed that they were so much quieter than the Bridgestones. The sidewalls of Bridgestones seem very light. Maybe that’s why they transmit so much noise. The sidewalls of the Yokahamas, on our Passat wagon seem much robust and those tires are very quiet.I would not buy the Bridgestones again.
