2023 Weird tire size and gas mileage: XLE 195/50R19 52MPG vs LE P195/60R17 57/56 MPG

The 17 in wheels with improve fuel economy, but they are still an odd size for the US, thus just as hard as the 19 in ones to find in the beginning.

 

Sit tight for a few years.

 

have you actually taken possession?

 

I intend to do this too. Will ask the dealer if they have any base 17" Primes being delivered to customers who'd like to swap for my 19s.

Eventually would like to put Nokian WRG4 all-weather tires on. kaltire.com already has the 2023 Prius in their configurator, but no tires available. Now we wait.

 

Agreed on the WRG4 or maybe Michelin CrossClimate 2.

Here's a list of all the tires I've found that match the Prius sizes exactly. It's probably not complete, but pretty close for the moment. All are Japan-only or Toyota-only right now, but I expect that will change over the next few months.

Code:

195/50R19
Toyo           Proxes Comfort IIs*        Summer/AS
Bridgestone    Ecopia NH200               Summer/AS
               Blizzak VRX3               Winter Studless
Yokohama       BluEarth-GT AE51*          Summer/AS

195/60R17
Toyo           Proxes Comfort IIs*        Summer/AS
               Observe GIZ2               Winter Studless
Bridgestone    Ecopia NH200               Summer/AS
               Blizzak VRX3               Winter Studless
               Blizzak VRX2               Winter Studless
Yokohama       BluEarth-FE AE30*          Summer/AS

*Toyota OEM tires

 

17" tire is the premium tire.

19" tire is the inferior-spec but better-looking tire.

 

Dropping down to the 17" wheels for 5 mpg increase is pretty big. Anyone happen to know the offset on the OE 17" wheels? Would be nice to find a nicer looking replacement at some point for the OE 19" to recoup that mpg. Planning to investigate Corolla offset and lug pattern or even older prius/Corolla wheel specs.
