XLE/Limited: 19” to 17” tire swap?

If you're not sure, there are a few resources that have helped me learn that might also help you.
Here's a link to a Gen5 thread that is more about pics and going max size installable, but also has some sizes that can be helpful to narrow down some of the specs needed when going custom wheels / tires.
Where’s the aftermarket wheel/tire thread? | PriusChat

than there is this site that covers almost everything needed, once all the fitment terms are understood.
TireSize.com - Compare Tire Sizes, Specs, Prices & more

And this site will do all the leg work even if you don't know what the terms mean.
Wheel-Size.com :: Global Wheel Fitment Database For Vehicles

And @Rob43 s thread with 14 pages of posts about the Gen4 tire and wheel fitment guide - it's a lot of reading, but it you really want to learn more about what the fitment terms mean, it's a great resource along with the other linked above.

That'll be fine. No need to get overly technical. Tires wear out soon enough and you can try different sizes anyway. I don't know why people make tires into such a big deal

 

Big deal? Maybe not but size does matter. Going with an over all size that is different will affect your speedometer and odometer readings as they are calibrated to work with a specific over all circumference of a tire. This will also affect HV/EV mpg/e-mpg.

 

I have similar concerns. I don’t have the car yet but I’m being told that the XLE AWD is a heavier car and partly why it has the larger tires?? Plus if I were to switch from 19 to 17 inch tires it could interfere with the AWD system. Something about messing with the differentials and that this can’t be adjusted to accommodate for the smaller tire.

Yes. I want the best gas mileage possible but I’m mostly concerned about these low profile tires and pot holes etc.

 

tire width remains the same with the swap. there is a 21.1% gain in sidewall albeit tire diameter is -1.9% smaller which is really fine. when your speedometer reads 60mph, the actual is closer to 58.9mph. it's fine.

 

There would be zero issues with AWD differential?

 

Correct, there would be zero issues with the AWD differential. I belong to other auto forums and this issue comes up all the time. The consensus is if you're within 3% difference of the original diameter, you'll be fine. Keep in mind that a wider tire, say for example going from 195 width to 215 width would have some impact of your MPG but it would be barely noticeable. See the following site for tire and size differences and how it would affect the car's performance. Rim & Tire Size Calculator. Custom Offsets - Wheel-Size.com

 

Oi

 

Have you tried the 195/60R17 on the AWD XLE? I just blew a tire today and the wait time for a new one is about 30 days! I asked the dealership about doing this switch, but they don't have any experience with the new Prius and don't know if it'll clear the brake calipers.

 

You should be fine. See the attached. Your speedometer will read 2% slower … and that’s assuming everything is perfectly calibrated to begin with.

 

I have a Prius 2023 LTD AWD, i installed aerodynamic mag 17 x 6.5J Fast EV01+ Titanium (Fast Part Number: FE01N(+)-1765-65TN+38C661) with 195/60R17 tire. It works really well and has 38 mm offset (Near Prius spec: 40 mm). I installed 66.1 mm to 60.1 mm hub ring and conical nuts with these wheels.
