Spare Tire Sizing

Aspect Ratio- Wheel Diameter vs tire diameter

• The Modern Spare specified for my vehicle model is different in height (or diameter) than my regular tires. Is this okay?
• Would it not be better to get a fifth full-size wheel and tire to use as a spare? Why use a Modern Spare?
• How do I know the Modern Spare is the right size for my car?
• What are the dimensions of the spare tire and wheel combination?
• My vehicle has aftermarket brake caliper covers. Would your spare still work when these are installed?
• Do you offer custom spare tire sizes if I have aftermarket wheels/tires?
• What are the dimensions of your spare and how much does it weigh?
• My car has different tire sizes on the front and back wheels. Can the spare still be used for both the front and rear?
