Tire size for winter tires

No experience but here is an online calculator

 

If you are using four of the same size tire, the circumferential difference isn't an issue for ABS, TC, etc.
.
If the rims have the same bolt circle, backset and center bore, the rims should mount and clear the brake calipers and you should be OK.

The v Five wears 215/50R17 tires, so fender well clearance should not be an issue.

 

One key to wheel fitment is something called offset. In laymans terms, it is how far the wheel center is going to be from the axle hub.

Together with tire size and wheel size and width, these combine to tell if the tire will fit in the wheel well and if there will be any brake component interference.

That is why the calculator asks for more than a few variables.

 

IIRC there was a Camry steel rim being used with snow tires on the Prius v. FYI I'm using a Corolla rim for snows on a regular Prius. Bottom line, there are commonalities, sharing of parts/dimensions.

 

As for the OP, bring one of the snow tires to the dealer and have him prove it will mount successfully and clear. They want the sale ...

 

Winter is when you could use the extra ride height to help clear some obstacles, how much can I get away with is the question? One up size should work, 2 up size maybe and pushing to 3 up size is pushing it. I'm about to try it so crossing fingers. I know my speedo will be off by roughly 5km/h.

 

I'm using my 2004 Sienna wheels to see how big I could put on a Prius V. I'm trying 225/65/16 which is 3 up. Slight rub on inner rear plastic cover on turns and I bottomed out on a dip in the road. Slightly to big. The tires are about 1/2" wider and over 1" taller. I will try another size 215/60/16 and see. I should be using the same width and increase the sidewall but I'm using what's at my disposal.
