205/65-15 5.2in 12.7in 25.5in 80.1in 791 7.4%
So you are actually going further than you thought! If the 185/60 R15 size is stock for your car then the odometer will be set for that.
If you haven't had your odometer adjusted for your new tires then you are actually traveling further than you think... Look out for speed traps you'll be going much faster than your speedometer reading too! (Assuming it was good in the first place that is) |
Since this kind of stuff demands utmost accuracy, I would be remiss if I didn't point out that the stock tire size is 185/65-15 not 185/60-15. So that makes the difference between what the odo is geared for and what we actually have now with the 205/65-15s slightly smaller. (I realize you were just using the sizes supplied by Ismalley.)
