So I'm playing with the idea of buying dedicated winter tires, on rims so I can swap and go when need be. I haven't had a real winter consistently around here, few weeks here and there. Last year was decent, but the A/S Dunflops did reasonably well on the roads. I had a bad day getting up to Mt. St. Helens, specifically pulling too far off the road to let pickups with trailers pass on a narrow road, and making the mistake of coming to a complete stop. The AWD system on this car is a gimmick, plus disengagement of traction control does not work with the Lexus cars, IDK why the need the play God there, but whatever. So, there are infrequent events of need for a better winter tire.
I've been looking for rims and the OE size ranges from 18" and up, width between 7.5 and 9, with the average offset of 35. Looking around the web and trying to make sense of things with no real knowledge, it seems I can get away with 17" rim for sure, and other cars getting away with 16" rims for similar brake rotor size.
What do I do to figure out the minimum rim size for (any) car?
