I'd like to put snow tires on our leased 2017 Volt. Now that I've read about and understand the tire size naming convention (stock tires are 215/50R17) and the benefits of minus-sizing, I'm curious about how closely one really needs to match the tire diameter. Obviously, if I were going down to 16 inch rims and buying new snow tires, I would attempt to match the tire diameter as closely as possible, however, I happen to have a set of studded snows from my previous lease (Nissan Leaf). Those tires are 205/55R16. Can I safely use those tires on my Volt? Obviously, they would need their own set of 16" rims (they are currently unmounted) - but that would make swapping between the summer and winter tires much easier than the mounting/balancing that I had to do twice a year with the tires on Leaf.
The math works out that the snow tires I have are 2.3% smaller in overall diameter. I have so far found only a few references to recommended difference in size between the original tires and any new ones. One site claimed that you want < 1% difference and optimally <0.5% (that's actually not always easy achieve even when you get to pick the size). Another said that most tire sellers say that <3% is fine (and in fact I found that 3% number quoted on 1010tires.com).
So, is it safe to get some 16" rims for the studded snow tires in my shed and use them on my Volt, saving a lot of money? Or is that inadvisable because of the size difference, or other reason?
Also, would I need anything else, like tpms sensors? Would any 16" rims work, or does the Volt need something special?
Thanks.
