Tire Size Calculator - tire & wheel plus sizing
That's a better tire calculator.
Usually you wanna stay within 3% of your stock diameter Rim/Tire combo.. What you have on is not only too small and probably rides pretty rough.. but it's 4.36% too small.
It says your speedometer will be off by 4.556%.
So if your speedometer says 63 mph, you're actually going 60 mph.
235-55-17's are a nice size tire for 17's, they are nice and meaty and look great. They are only slightly bigger then stock diameter.
