Alternative Tires
If the exact replacement cannot be found, tire sizes can be interchanged in a limited manner. However, alternative sized tires should be approved by the vehicle manufacturer and only used in pairs (on the same axle). The tire diameter (rim or wheel size) must always be the same as the original in order to perfectly fit the wheel. Be certain to observe restrictions on tire mixing in Safety Tips.
For example, a worn or flat tire with size P185/60R13 could be replaced with a P195/60R13 or P215/50R13 tire, but remember the opposite tire (even if good) would need to be replaced as well for a perfect size match.
