It’s National Donut Day, so we thought it would be a great time to answer some common questions about your vehicle’s donut spare tire.
How Long Can You Run On A Donut Spare Tire?
About seventy miles is the rule of thumb. Spares are not meant to be used for long-range travel and instead are meant to get you to a garage to have your tire either repaired or replaced. Keeping a donut on your car and driving for an extended period of time under regular driving conditions may cause a blowout.
What is a A ‘Donut’ Spare Tire?
Donut spare tires typically offer very little thread and no reinforcement with no tread belt to protect it from projectiles and road imperfections.
Will The Donut Affect the Braking or Suspension?
Poor cornering, handling, and braking characteristics can be expected with a donut spare as it normally has a smaller footprint than a standard-sized tire. With the donut spare in place, you may find that the vehicle dips to the side where the donut was mounted when braking and the car may list as you travel.
Why Do Carmakers Include These Donuts Instead of Full Size Spare Tires?
To save space and costs. The donut spare takes up much less space and is less expensive to make.
Can I Put A Full Size Spare On My Car?
Some car owners may opt to switch out their donut spare for a full-size tire; however, you should consider storage as many auto makers have removed wheel wells and may not even offer a spare tire at all and instead may have opted to equip your vehicle with run-flat tires.
