Are the 17" tires really that much better for Gen 5?

They might get sticker-shock when tire replacement is needed.

 

Hello, just not clarify
Are you stating that you are using Michelin 225/18 A/S4 tires will fit on a 2025 Prius OEM rims that came with 19" tires ?
Also I am a bit confused as there are multiple "225/18" tires listed on the Michelin site.

What actual width 225/ ??? R18 Michelin tire are you using on the OEM rims ?

 

I have 16's for my winter tires, 17's for summer

 

Thanks Blackcat, but also did not fully specify your complete tire size. Tired are sized of the format of XXX/YY R(##).
Not to be rude, but your post is just the R(##) portion of a tire size.
I am just a Prius newbie here trying to understand all of the various tires sizes in play.

 

Aren't your 16" wheels quite close to your front brakes? And aren't they an aftermarket wheel?

My thought with the Prius V wheels was that I wouldn't have to buy and keep track of another set of lug nuts, but 17" seems a safer bet for wheels that will clear the brakes.

 

I have a 2026 Limited AWD on order. The OEM tires will be 1195/50R19. I would like to know what (Michelin) 18" tires sized will fit and have been used by others on this forum with a 2023/24 Limited AWD car.

 

Just to be very clear, 18 inch tires by ANY manufacturer, will NOT fit onto the OEM 19 inch rims/wheels.

It seems that you are misunderstanding the discussion.

The 18 and 17 inch tires being discussed are all mounted on another set of wheels/rims either aftermarket or OEM rims from another model/make car that is compatible with the bolt pattern and wheel offset of the Prius.


SM-S936U ?

 

Good tool for keeping OD similar, with alternate tire sizes:

Depending on the rim, you need to also be careful with the tire width.
