The Modern Spare specified for my vehicle model is different in height (or diameter) than my regular tires. Is this okay?

Yes, for some models, the spare tire's diameter may not exactly match that of your regular tires.

This may seem contrary to similar frequently asked questions that mention the importance of proper spare tire sizing.  

Rest assured that all Modern Spare spare tires are sized for safe, long-range use on your vehicle. This even applies to those models with advanced AWD systems. 

There are a number of factors that determine the ideal size for your spare tire. 

  • Vehicle weight and tire pressure can determine the effective "rolling diameter" of a spare tire, even if it appears to be slightly different. 
  • Modern vehicles have a built-in tolerance, allowing for a slightly different spare tire size.
  • If your Modern Spare does not exactly match your regular tire diameter, the spare is designed to be sized well within this tolerance. 
  • To take advantage of the existing storage space in your car, Modern Spare may utilize a smaller spare, but only if the size does not strain your vehicle's drivetrain during use. 
  • Important sizing factors will vary widely between each vehicle manufacturer. Modern Spare designs spare tires specific to the needs of your make and model.
