Ever found yourself asking, “how long can you drive on a spare tire?” Well, you’re not alone, and this article is crafted just for you. A common guideline is to drive no more than 70 miles and no faster than 50 miles per hour before replacing your spare tire.
A spare tire, specifically a compact spare, is designed for emergency use and should not be driven on for long distances or at high speeds. They are made for short-term use to get you to a safe location or a nearby auto shop where your flat tire can be repaired or replaced.
The Limits of a Spare Tire
A spare tire, often known as a “donut,” is typically smaller and not as durable as regular tires. These temporary solutions are made with lighter materials and less tread, making them less suitable for long-distance driving or harsh weather conditions.
Risks of Driving on a Spare Tire
Driving on a spare tire for extended periods or at high speeds can be risky. Due to their reduced size and durability, spares do not handle the same way as regular tires. They can adversely affect your car’s handling and stopping distance, which could potentially lead to accidents. Furthermore, driving on a spare tire for longer than recommended could cause damage to other components of your vehicle, such as the differential.
Safety Tips When Driving on a Spare Tire
When you have a spare tire installed, it’s crucial to drive cautiously and consider the following safety tips:
- Drive at reduced speeds: Since spare tires are not built for speed, try to keep your speed under 50 mph.
- Avoid driving long distances: Aim to travel only as far as you need to get your regular tire repaired or replaced, ideally within 70 miles.
- Check tire pressure: Ensure your spare is properly inflated before you start driving.
Regular Tire Maintenance
The best way to avoid relying on a spare tire is to maintain your regular tires. Regular inspections for cuts, punctures, and under-inflation can help you detect problems early and address them promptly, reducing the chance of unexpected flats.
While a spare tire is a handy temporary solution, it’s not a long-term fix. Knowing how long you can drive on a spare tire and understanding the risks of exceeding these limits is crucial for your safety and the health of your vehicle. Always remember, regular tire maintenance is your best line of defense against unexpected flats and the need for a spare.
How to Install a Spare Tire: A Simple Step-by-Step Guide
Step 1: Preparing for the Installation
Before you start, ensure that your vehicle is parked on a flat, stable surface away from traffic. Turn on your hazard lights and apply the parking brake for safety.
Step 2: Removing the Wheel
Locate and remove your vehicle’s lug wrench and jack from the trunk. Use the wrench to loosen the lug nuts on the wheel you’ll be replacing (don’t remove them yet). After that, place the jack under the vehicle’s frame near the wheel you’re changing, and pump or twist it until the wheel is lifted off the ground.
Step 3: Unmounting the Old Tire
Once the wheel is off the ground, fully unscrew the lug nuts and put them aside in a safe place. Grasp the wheel and gently pull it towards you until it’s free from the hub.
Step 4: Installing the Spare Tire
Align the holes of the spare tire with the bolts on the hub. Push the spare onto the hub until it can’t go any further.
Step 5: Securing the Spare Tire
Put the lug nuts back on the bolts and tighten them by hand as much as you can. Then lower the car using the jack until it’s back on the ground.
Step 6: Final Tightening and Checking
Using the lug wrench, tighten the nuts as much as possible. Finally, check the spare tire’s pressure and inflate it to the recommended PSI if necessary.
Remember, the spare tire is a temporary solution. Get your tire fixed or replaced as soon as you can, and drive at a reduced speed while using the spare.
