Non-Run Flat Winter Tire/wheel question

I recently purchased a 2019 UX Hybrid AWD luxury edition vehicle and looking at putting winter tires on the vehicle. I just wondered if there’s any specific size and or rim requirement for the Hybrid. As you know the UX Hybrid comes standard with 18” run flats.
Reason I ask is I have a nearly new set of 17 inch Bridgestone Blizzak tires mounted on Lexus 17” rims from my wife’s previous 2006 IS. I am not concerned with using non run flat winter tires as I previously ran in my previous BMW and we don’t venture too far from home in winter. The difference is of course that the UX is a hybrid and with brake regeneration I wonder if there is an issue using the older IS Rim as well as dropping an inch in tire/wheel size.
Appreciate any input.

The wheel diameter doesn't matter as much as the tire diameter. You'll want a taller sidewall tire to compensate for that inch. If the overall diameter is different, your speedometer/odometer will be off, and your ride and handling may be compromised. Not to mention, you probably don't want to be riding lower in the snow.
You have 225/50 R18s. So a 225/55 R17 tire would probably be closest in diameter.

Thanks for replies, I’m going to just buy same size as stock tires and rims.

TIRE SIZES
When your Lexus vehicle was designed, the engineers and product planners carefully selected a tire size, considering many factors, including performance, safety, and fuel efficiency. Lexus recommends that you select the original tire size when selecting winter, performance, or all-season replacement tires.Last edited by Jimmy3864; 10-29-20 at 01:14 AM.
