Four Touring 17" tire options?

Not sure if you are aware, but the Ecopia 422 Plus was one of Toyota’s original equipment selections.

My OEM version was made in Japan, but my replacement set was made in Mexico with very slightly different specs.

 

In the past I have used Michelin Energy Saver and HydroEdge from Costco on my Prius. Hydroedge was very noisy especially when new and didn't seem to handle that great so the next time I needed tires I planned to go back to Energy Saver, however Costco didn't carry that one anymore but they had Premier A/S. I read good reviews about it but the comments in PriusChat indicated that it was not as good for gas mileage. Went with them and have really enjoyed them, quiet, good handling, best tire I have run on my Gen 2. But I did take about a 1 or 2 mpg hit in gas mileage.

 

For other options, check out Tirerack.com. We have used Continental True Contact on earlier Prius and plan on this again when our Three Touring needs tires. Print the price quote from Tirerack.com and take it to your local installer. They will match or even beat the Tirerack quote to get your business.

 

I'm leaning towards Michelin Primacy MXM4. They have the Green-X label. Here's the tale of a guy that started with Premiers, then swapped to Primacy:

Costco should have the Primacy's as well; put in your car on their website to verify.

The other option at Costco is Pilot HX MXM4, but they are always bizarrely expensive. It's odd too, our OEMs were the Pilots, still rolling on them (one more year, one more year): ours have the Green-X label, but according to TireRack at least, when you buy them retail they are not Green-X. Not sure what's going on there.

 

Some are reporting significant mpg drop with the Premiers, @jimmyjam for example (in my link). OTOH, @The Critic liked them I think (in a review at bobistheoilguy) and @bisco also liked them, on their Camry, mentioned good mpg on a road trip. A toss up I guess.

They start off with only 8.5/32" tread depth fwiw, supposedly the traction is more reliable all the way down, due to sipes opening up as the tire wears.
