Why doesnt Acura have a spare tire?

Most Acura models no longer include a traditional spare tire; instead, they rely on a tire repair kit and inflator or run-flat tires, with roadside assistance as backup.

What changed and why

Automakers like Acura have shifted away from carrying a full-size spare to reduce weight, free up trunk space, and improve overall efficiency. The move also aligns with a broader trend toward lightweight, modular repair options and enhanced roadside support, rather than relying on a single spare tire for emergencies.

Model-by-model differences

Across recent Acura models—such as the MDX, RDX, and TLX—the standard equipment commonly includes a sealant-based tire repair kit and a portable air compressor. Some trims in certain markets may still offer a space-saver spare as an option or in specific configurations, but the default US-spec setup has generally moved away from a traditional spare.

Key reasons the approach is widespread:



• Weight reduction improves fuel economy and handling


• More usable trunk space for cargo and cargo flexibility


• Lower manufacturing and material costs


• Continued access to roadside assistance as a service-based safety net

The combination of these factors helps explain why Acura, like many other brands, has largely replaced the spare tire with a repair kit and supportive services.

What to know as an owner

Most models ship with a tire repair kit and inflator, and some markets or trims may offer a space-saver spare as an option. Run-flat tires are not universally used across the lineup, so owners should verify their specific vehicle’s equipment in the owner's manual or with a dealer.

How to handle a flat

If you encounter a flat, you can usually use the included tire sealant and inflator for a temporary fix if the puncture is repairable. For more serious damage or if the kit cannot restore proper inflation, contact roadside assistance for a tow to a tire shop. Always confirm you have access to the kit and understand its instructions before you need it.

1. Park safely on a flat surface and turn on hazard lights.


2. Open the kit and follow the included instructions to seal and inflate the tire if appropriate.


3. If the tire cannot be repaired or cannot be safely inflated, call roadside assistance for a tow.


4. Consider whether you want to add a spare tire or an accessory kit in the future, especially for trips in remote areas.

The repair kit provides a temporary solution; after any incident, have the tire inspected or replaced as soon as possible.

Regional and model variations

In North America, most Acura models follow the tire-repair-kit approach rather than a traditional spare. In some markets or on certain trims, a space-saver spare may be offered as an option. Always verify the exact equipment for your model year with the dealer or in the owner's manual, as configurations can vary by year and region.

Summary

Acura’s move away from a conventional spare tire reflects a broader industry trend toward lighter, more space-efficient interiors and reliance on temporary repair solutions plus roadside support. For most owners, this means a tire sealant kit and inflator for minor punctures, or a tow to service if the damage is too severe, with the option to add a spare or different tire package if desired.

Does the 2025 Acura MDX have a spare tire?

The 2025 Acura MDX comes with a spare tire, but it depends on the drivetrain and trim level. All-wheel drive (AWD) models typically include a spare, while front-wheel drive models do not. The Type S model does not come with a spare tire, regardless of the drivetrain, though one can be purchased separately. 

• Models with a spare tire: Most SH-AWD (Super Handling All-Wheel Drive) models come standard with a spare tire, often a compact spare mounted underneath the vehicle. 
• Models without a spare tire: Front-wheel drive and the Type S trims do not have a spare tire. 
• What to do if you don't have a spare: If your MDX does not come with a spare, it will likely have a tire inflator kit instead. You can also purchase a spare tire kit from an aftermarket supplier. 

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.

Do Acura cars have spare tires?

Whether an Acura comes with a spare tire depends on the model and trim level, with some models coming equipped with a spare while others include a tire sealant and inflation kit instead. For example, some RDX models include a spare, but the A-Spec and A-Spec Advance trims do not, and other models like the TLX may also lack a spare depending on the year and configuration. 
Models with a spare tire

• RDX (non-A-Spec trims): The RDX comes with a spare tire on trims like the RDX, Technology Package, and Advance. 
• Other models: Some other Acura models, such as the TLX and MDX, may come with either a compact or full-size spare tire, though this varies. 

Models with a tire sealant kit

• RDX (A-Spec and A-Spec Advance trims): These trims are equipped with a tire sealant and inflation kit instead of a spare. 
• Other models: Some models, to save space and weight, are equipped with a tire sealant kit instead of a spare tire. 

What to do if your car lacks a spare

• Check your trunk: Look for a tire sealant and inflation kit. The kit will contain a bottle of sealant and a portable air compressor. 
• Purchase a spare tire kit: If you prefer a spare tire, you can often purchase one separately from a dealership or online. Some owners have successfully installed a full-size spare tire and hoist kit in place of the factory sealant kit. 
• Contact roadside assistance: If you have a flat and no spare, you can call for roadside assistance. However, this can result in a significant delay. 

Why do new cars no longer have spare tires?

New cars don't come with a spare tire to reduce weight for better fuel economy, save manufacturing costs, and create more space for other features like batteries or cargo. Many vehicles now include alternatives to a spare, such as tire repair kits or run-flat tires.
 
Reasons for removing spare tires

• Weight and efficiency: Removing the spare tire and jack saves 30 to 50 pounds, which improves the car's fuel efficiency and helps manufacturers meet EPA guidelines. 
• Cost savings: Eliminating the spare tire and the components needed to mount it saves the manufacturer money on materials and production. 
• More space: Removing the spare tire creates extra space, which can be used for larger batteries in electric and hybrid vehicles, increased cargo room, or other features. 
• Alternative solutions: Many cars now come with a tire repair kit, which includes sealant and an air pump for temporary fixes. Luxury or performance models may feature run-flat tires, which can be driven for a limited distance after a puncture. 

What this means for drivers

• Check before you buy: Don't assume a new car has a spare. Check the vehicle's specifications to see if it includes one or a repair kit. 
• Be prepared: If your car has a tire repair kit instead of a spare, familiarize yourself with how to use it. It's a temporary solution meant to get you to a repair shop. 
• Consider roadside assistance: With the elimination of spare tires, many drivers rely on roadside assistance for flat tires.
