205/60 15
215/50 16
225/40 17
do they all have the same rolling circumference?
factory is 205/60 15
any of the others will be ok?
thanks

For more on marking an answer as the "Best Answer", please visit our FAQ.205/60 15 means as follows:
205 is the width (in millimetres) of the tread. 60 is the profile ratio of the tyre (i.e. its wall height is 60% of the tread width). 15 is its diameter in inches.
Only tyres of 15 inches diameter will fit a 15 inch rim. However you can vary the tread width and profile slightly.
A low profile tyre (one where the profile ratio is low) will have a smaller rolling circumference than a higher profile tyre. This is because although the rim diameter is the same the �height� of the tyre will be less. So the diameter of the tyre (and hence its circumference) will be less.
Ideally you should not depart from the factory fitted spec. However, consult a tyre dealer if you intend to do so.
