225/45/17 Circumference 78.45

With your current 225/50/-16… if your speedometer now reads 65… with the 225/45-17 it will read 65.29

The tire width for both tires sizes is the same… 8.86

I'm with Keith on this selection.

Standard size on the SVX rims would be 225/50/16. Maintaining the rolling radius while growing the rim part means going down 5% per inch. So:

225/50/16 ~ 225/45/17 ~225/40/18

Going to a wider tire at 235 or 245 is seductive I know, but the ride will be wallowy on bends. Handling will be tighter on stock width or even slightly narrower at 215 like the factory did with the '97s.
