215/60R16 vs 205/60R16
Fitting 205/60R16 in place of 215/60R16 changes rolling diameter by −1.8%, which is inside the 3% tolerance the industry treats as a safe substitution. The tyre is shorter and 10 mm narrower, so you need roughly 6.0 mm of extra room at the top of the arch and at the strut. Speedometer error stays small enough that most drivers never notice it, and ABS and traction control will continue to work from calibration.

Questions about this swap
›Can I fit 205/60R16 instead of 215/60R16?
Yes, in most cases. The −1.8% diameter change is inside the 3% tolerance for a safe substitution, provided load index and speed rating match or exceed the original.
›How much will my speedometer be out with 205/60R16 instead of 215/60R16?
By about 1.8%. At an indicated 60 mph you would actually be doing 58.9 mph, so the dial over-reads your true speed.
›Does fitting 205/60R16 change ride height from 215/60R16?
Yes, by roughly 6.0 mm. Rolling radius is half the diameter change, so the axle sits that much lower and you need the same amount of extra room above the tyre.
›Will my odometer read differently on 205/60R16 rather than 215/60R16?
It will read 1.8% high. Over 10,000 recorded miles that is about 181 miles of difference against the true distance travelled.
