Comparison of Spare Wheel Types for Rally Cars
| Feature | Full-Size Spare | Space-Saver Spare | Run-Flat Tire |
|---|---|---|---|

What are the Benefits of a Full-Size Spare?
A full-size spare offers the same performance as a regular tire, allowing you to continue driving under normal conditions without limitations. Unlike space-saver spares, they don’t compromise handling or safety, making them ideal for rally racing.
How Often Should You Check Your Spare Wheel?
Regularly inspect your spare wheel for air pressure, tread condition, and overall integrity. Check it at least once a month and before any rally event to ensure it’s ready for use.
Can You Use Any Spare Wheel on a Rally Car?
Not all spare wheels are suitable for rally cars. Ensure the spare matches the specifications of your regular wheels, including size, weight, and load capacity, to maintain optimal performance and safety.
What Should You Do After Mounting a Spare Wheel?
After mounting, drive cautiously to a service area for a permanent tire replacement or repair. Even if the spare is full-size, it’s wise to have the original tire inspected and repaired by a professional.
