Why do electric cars not have a spare wheel?
Most electric cars do not come with a traditional full-size spare wheel. Instead, manufacturers typically include a tire repair kit or run-flat tires, paired with roadside assistance, to handle punctures. This approach helps maximize range and frees space for the larger battery pack.
As engineers place the large battery pack in the floor of an EV, interior and cargo space must be carefully managed. The result is a packaging challenge that often makes a conventional spare wheel impractical or unnecessarily costly. Rather than a spare, many buyers rely on repair systems and service networks to fix or replace a tire when needed.
Design, packaging and efficiency reasons
Packaging and engineering constraints
The battery sits under the floor, limiting room for a traditional spare wheel without raising the vehicle floor, reducing cargo space, or complicating cooling and suspension geometry. This constraint is a core reason why a spare wheel is often omitted from new designs.
- Battery placement and interior packaging: A full-size spare wheel would intrude on cargo space and could complicate the battery’s cooling and thermal management.
- Weight and efficiency: A spare adds unsprung and overall weight, which erodes range and efficiency—critical metrics for EVs.
- Cost and maintenance: Spare wheels require hardware, jacks, and storage space; replacing them with repair kits lowers upfront cost and ongoing maintenance needs.
- Ride quality and safety considerations: Many EVs use low-profile or wide tires whose temporary use wheels are not ideal for extended driving, making a repair kit a simpler solution for most punctures.
- Repair logistics and service networks: Automakers increasingly rely on roadside assistance and quick tire replacements at service centers, reducing the need for an in-car spare.
In short, the design priorities of electric cars—space for the battery, weight control, cost efficiency, and reliable service options—drive the move away from a traditional spare wheel.
What alternatives do EVs use instead of a spare
Common equipment and services
Rather than a full-size spare, EVs commonly rely on one or more of these solutions to address tire issues on the road.
- Tire repair kit with sealant and a portable air compressor
- Run-flat tires that can be driven for a limited distance after a puncture
- Space-saving or temporary spare wheels offered as an option or in certain markets
- Comprehensive roadside assistance and mobile tire repair services
These options enable a quick temporary remedy or safe removal from the road, while keeping the vehicle lighter and the interior more spacious for the battery and cargo.
What to do if you get a puncture
Steps for safe handling
If you encounter a puncture in an EV, follow standard safety procedures and use the vehicle’s available tools or services to minimize risk and downtime.
- Safely pull over to a secure location and activate hazard lights.
- If you have a tire repair kit, follow the manufacturer’s instructions to seal and inflate the tire using the included compressor.
- If the tire cannot be repaired or is severely damaged, contact roadside assistance or your vehicle’s emergency tire service for help or to arrange towing.
- Do not drive long distances on a severely damaged tire or beyond the limits of a temporary fix; seek professional tire service as soon as possible.
Most manufacturers offer roadside support or mobile tire services as part of maintenance plans, warranties, or subscription programs, providing a practical safety net when a puncture occurs away from a service center.
Summary
Electric cars generally omit a traditional spare wheel because large battery packs impose space and weight constraints, and because modern repair solutions—tire sealants, run-flat tires, and roadside assistance—address punctures effectively. While some models or markets may offer a space-saving spare as an option, the prevailing approach prioritizes range, efficiency, and straightforward service access. Drivers should know how to use the repair kit if provided, understand their vehicle’s guidance on punctures, and plan for professional tire service when needed.
Why do Teslas not have spare tires?
Teslas do not have spare tires primarily to save weight and space, improve range, and because the company relies on other solutions like roadside assistance and tire repair kits. Eliminating a spare allows for more cargo or passenger space, contributes to better efficiency by reducing weight, and simplifies the vehicle's design. The assumption is that most punctures can be fixed with a repair kit, or the driver can use Tesla's mobile service or roadside assistance for more serious issues.
- Weight reduction: Removing the spare tire and jack saves weight, which directly helps improve a vehicle's efficiency and driving range, especially critical for EVs like Teslas.
- Space optimization: The battery pack in EVs occupies the space where a traditional spare tire would be stored. Removing the spare also creates more cargo space in the trunk.
- Tire technology: Modern tires, including those used on many Teslas, can often be driven for a short distance even after a puncture, giving the driver enough time to reach a repair location. Some models also include a tire repair kit for temporary fixes.
- Roadside assistance: Tesla offers a 24/7 roadside assistance program, including a mobile repair service in many areas, which is intended to handle flat tire situations without the need for a spare.
- Industry trend: The elimination of spare tires is a growing trend in the automotive industry, not just with EVs, to reduce costs, save weight, and create more interior space.

Why do Teslas get so many flat tires?
Teslas may get more flat tires due to their high weight, instant torque, and the low-profile tires used on many models, which increase strain and reduce protection from road hazards. The combination of vehicle weight and instant acceleration puts extra stress on tires, and low-profile tires with smaller sidewalls are more vulnerable to damage from potholes and road debris. While some external factors like road conditions and construction zones play a large role, the vehicle's design characteristics are significant contributors to the increased rate of tire issues.
Vehicle design
- Weight: Teslas are significantly heavier than traditional gasoline cars due to their battery packs, which puts more strain on the tires.
- Instant torque: Electric motors deliver instant and high torque, which can cause tires to wear down faster and even "spin" on the road if acceleration is aggressive.
- Low-profile tires: Many Teslas are equipped with low-profile tires that have a smaller sidewall. This makes them less able to absorb impacts from potholes and road hazards, increasing the risk of damage.
External factors
- Road conditions: Potholes, nails, screws, and other road debris can easily lead to a flat tire, especially in areas with poor road maintenance or heavy construction.
- Driving habits: Aggressive driving, such as frequent hard acceleration and cornering, will put more stress on the tires and accelerate wear.
Tire technology
- Noise-dampening foam: Many Tesla tires have a special foam liner to reduce road noise. While this helps with the driving experience, the foam can make some tire shops less equipped to handle a flat.
- High performance: Some Tesla models come with high-performance tires designed for optimal grip, which can sometimes have a softer compound that wears faster.
What do I do if I get a flat tire and have no spare?
Easiest option is to simply call a tow truck. Get towed to the tire repair shop , get a coffee, and be waiting when they open.
Why don't electric cars have spare wheels?
Electric cars often don't have spare tires because removing them saves weight and space, which improves efficiency and allows for more cargo or battery capacity. Manufacturers also rely on alternatives like run-flat tires, tire repair kits, and roadside assistance, while arguing that modern tires are more durable and most drivers are unlikely to need a spare.
Reasons for removing spare tires
- Weight savings: Eliminating a spare tire and jack reduces overall weight, which can help improve the vehicle's range and efficiency.
- Space constraints: The "skateboard" design of many EVs, with the battery located in the floor, leaves little room for a spare tire. Removing it allows for more cargo space or a larger battery.
- Cost reduction: Not including a spare and its tools saves the manufacturer money on production costs.
- Improved tire technology: Modern tires are more durable, and the increased use of tire pressure monitoring systems (TPMS) gives drivers early warning of a flat, making a spare less necessary.
- Alternative solutions: Many EVs come with a tire repair kit or run-flat tires instead of a spare. Roadside assistance is also widely available.
