The one thing with the 225/45 is that I was reading that the minimum rim width is 7 inches, max was like 8 (I think). The 225/15 and 225/50 are okay from 6.5-8.5 or something similar.
My stockers are the 7 inch, so it would be the minimum for the 45 series. Someone said that it wasn't a good idea to put a wider tire on the minimum recommended rim width.
A 7" rim is within the range specified for a 225/45R17 tire; that is all you need to know. The specifications are made with a margin for error. It is physically possible to mount wider tires than that on narrower rims than that: I once had 245
section width tires on 6.5"
rims (again, those were within the tire maker's specs for the tire in question). I find it hard to believe myself when I say this, but trust the tire maker to know the tire's capabilities,
Bridgestone or Dunlop????
I have close ties to Japan, have lived there for extended periods in the past; most of my family lives there, and I generally get there about once a year. So I generally have a pro-Japanese bias. But I never have warmed up to Bridgestone, which I associate with blandness, much as I associate Toyota with blandness. Among Japanese auto makers, I associate with Mazda because of the zoom-zoom factor, and I like Yokohama tires. But these days I am driving on Dunlop tires (originally Irish, became English, were purchased by Sumitomo, which after the Japanese Bubble burst parted the brand out to various makers; now North American Dunlop is part of GoodYear). As I intimated in an earlier post in this thread, when in doubt, follow the rayon and eschew the polyester.
