Tires size comparison

Is a tire that is marked as 215/65/15 any where close to the same as a 205/70/15.
Are they about the same size or how do they differ?
thanks in advance for your input

These tires will be close to the same height/diameter, they may even be the same. Go to your local tire store and ask - they have info on the height of all their tires and can tell you for sure.

Which tire is the correct tire and which is the replacement? Overall both tires are pretty close in diameter and if the 205/75-15 is the replacement tire your speedo will be off by 1.1% and it will read slower than your true speed. There's a website that calculates and compares tire sizes

215/65-15 sidewall 5.5"
205/70-15 sidewall 5.6"

215/65-15 radius 13.0"
205/70-15 radius 13.1"

215/65-15 dia. 26.0
205/70-15 dia. 26.3

215/65-15 circumference 81.7
205/70-15 circumference 82.6

215/65-15 rev/mile 776
205/70-15 rev/mile 767

difference of 1.1%
