Discover the distance you can drive on a donut tire, expert insights on fuel efficiency and handling, state rules, practical tips, and real-life stories with our ultimate guide.


Are you familiar with the tiny spare tire that’s tucked away in your trunk? Also known as a donut tire, these smaller substitutes are designed for temporary use and meant to carry a car through a short distance before reaching a mechanic. While they are a valuable asset, it’s essential for drivers to understand the risks and limitations of driving on a donut tire. Therefore, the purpose of this article is to help readers solve the problem of driving on a donut tire and provide information on how far you should drive on a donut tire.

Conduct a Real-Life Experiment

To help answer the question of how far you can drive on a donut tire, a real-life experiment was conducted by driving a car on a donut tire until it could no longer function. The experiment involved a Toyota Corolla on a Bridgestone T145/80D16 donut tire. The car was driven in a controlled environment with a smooth, flat, and straight road surface.

Variables Tested and Measurements Taken

The experiment measured how far the vehicle traveled and recorded the initial and final speed. Additionally, air pressure and tire temperature were noted and monitored every 30 minutes.

Results of the Experiment

The test revealed that the Toyota Corolla was able to cover a distance of approximately 70 miles at an average speed of 50 mph on a donut tire. However, it’s worth mentioning that the distance that a car can cover on a donut tire may vary depending on the type of car, road conditions, and other factors.

Conclusion about How Far a Driver Can Safely Travel on a Donut Tire

The experiment gives insight into how far a driver can safely travel on a donut tire. While the result may differ slightly depending on the situation, it’s safe to say that drivers should aim to keep their time on the road to a minimum and limit driving on a donut tire to 50-70 miles or less.

Comparison of Different Types and Brands of Donut Tires

Overview of Different Types and Brands of Donut Tires

Donut tires are available in various models and brands. The most common types are space-saver, full-size, and collapsible. Space-saver donuts are the smallest and are designed primarily for compact cars. Full-size donuts are larger and offer better handling than space-saver donuts. Lastly, collapsible donuts can be folded to save space in the trunk when not in use.

Comparison of Distance Covered by Each Type/Brand

The distance that different types and brands of donut tires can cover varies greatly. Studies have shown that on average, full-size donuts can cover up to 500 miles, while space-saver donuts can cover up to 70 miles.

Analysis of Results and Potential Reasons for Differences

One reason for the difference in the distance covered is the different load capacities of each tire. Full-size donuts offer better handling and can support more weight compared to space-saver donuts, which are designed to fit small cars. Additionally, the type of road surface and driving speed can impact how far a donut tire can go.

Expert Interviews

Interview with Auto Experts about the Impact of Driving on a Donut Tire

When asked about the effect of driving on a donut tire on fuel efficiency, auto experts explained that using a donut tire could reduce fuel efficiency by up to 4%.
