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 contradictory to other frequently asked questions that emphasize the significance of proper spare tire sizing. 
Rest assured, all Modern Spare tires are designed for safe, long-range use on your vehicle, including models equipped 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 influence the effective "rolling diameter" of a spare tire, even if it seems to be slightly different. 
  • Modern vehicles are designed with a built-in tolerance to accommodate slightly different spare tire sizes.
  • If your Modern Spare does not precisely match the diameter of your regular tire, it is designed to fall well within acceptable tolerance limits. 
  • To make use of the existing storage space in your car, Modern Spare may use a smaller spare, but only if the size does not put stress on your vehicle's drivetrain during use. 
  • Sizing factors can differ significantly among vehicle manufacturers. Modern Spare creates spare tires tailored to the requirements of your make and model.
