Does the 2024 RX 350 have a spare tire?

The 2024 RX 350 does not include a traditional full-size spare tire in most markets; instead it relies on a tire sealant kit and inflator for temporary repairs. A compact spare may be offered in some trims or regions, but it is not standard in the US-spec model.

In this article, we explore what Lexus says about the emergency setup, what you’ll typically find in the trunk, regional variations, and practical steps for handling a tire issue with this vehicle.

Official equipment and what the owner’s manual states

Lexus documentation for the 2024 RX 350 emphasizes an emergency setup centered on a tire sealant kit with an inflator rather than a traditional spare tire. The owner’s manual provides instructions for using the sealant kit and notes limitations of temporary repairs.

• Tire sealant and inflator kit for temporary repairs


• No standard full-size spare tire on most US-market RX 350 models


• Some markets or trims may include a compact spare wheel

In short, the standard US specification relies on the tire sealant kit rather than a conventional spare, with potential regional variations noted by Lexus.

What to do if you get a flat tire

If you experience a tire issue, follow these recommended steps to stay safe and minimize disruption while you arrange proper service.

1. Find a safe location and activate hazard lights; pull over away from traffic as soon as possible.


2. Consult the owner’s manual for the recommended procedure and inspect the sealant kit and tire sidewall for damage.


3. If the sealant kit can repair the tire, follow the instructions to seal and inflate; drive cautiously to a service center for a professional assessment.


4. If the tire cannot be repaired using the kit, contact Lexus Roadside Assistance or your local tow service for transport to a tire shop or Lexus service center.


5. After service, replace or repair the tire as needed and verify the emergency equipment for future use; check the kit’s expiration date and replacement parts if required.

These steps help ensure your safety and get you back on the road with a proper tire solution as soon as possible.

Regional variations and model-year considerations

United States and Canada

In the United States, the 2024 RX 350 generally ships without a traditional spare tire, relying on a tire sealant kit for temporary fixes. Canada follows similar practice, though specifications can vary by dealer or trim level.

Other markets

Some international markets or specific trims may offer a compact spare as part of the emergency equipment. Always verify the exact contents of your vehicle’s toolkit by consulting the owner’s manual or checking the trunk layout for your exact market configuration.

Why manufacturers move away from spare tires

Automakers reduce weight, save space, and cut costs by favoring sealant kits and roadside assistance over full spare tires. While this approach speeds up repairs and can lower overall vehicle weight, it also means drivers must rely on sealant repairs or towing rather than swapping in a spare wheel in many situations.

Summary

The 2024 Lexus RX 350 typically does not come with a traditional spare tire in the US, instead relying on a tire sealant kit and inflator for temporary repairs. A compact spare may be available in some markets or trims. Always confirm your specific vehicle’s emergency equipment by reviewing the owner’s manual and inspecting the trunk area to understand exactly what is included for your model and region.

Does the Lexus RX350 have a spare tire?

Yes, the Lexus RX 350 typically comes with a spare tire, which is a compact or "donut" spare on most newer models (2022-present) and a full-size spare on some older models. It is usually located underneath the cargo area and requires a special tool kit, also stored under the cargo floor, to access and lower.

Location and access

• The spare tire is stored flat under the rear cargo area floor. 
• To access it, lift the carpeted floor panel in the trunk and retrieve the tools, which are in a storage compartment beneath. You will find a jack and lug nut wrench in this kit. 
• Use the included tool to unscrew a central bolt that will lower the spare tire from the underbody of the vehicle. 

Type of spare

• Older models (e.g., 2014): Some older RX 350s may come with a full-size spare. 
• Newer models (e.g., 2022-present): Most newer models are equipped with a temporary, compact "donut" spare. It's essential to be aware of the limitations of these spares (e.g., speed and distance restrictions) and to get the flat tire fixed or replaced as soon as possible. 

Special considerations for newer models

• If your newer model RX 350 has the F-Sport package or a big brake kit, it may not come with a spare tire at all. Instead, it might have a tire repair kit or be prepared for the vehicle to be equipped with run-flat tires. 

Where is the spare tire on a 2024?

The 2024 spare tire location varies by model, but it is most commonly found in the trunk under a floor panel, underneath the rear of the vehicle, or mounted in the truck bed. To access it, you'll typically need to lift up the cargo floor cover or lower the spare from the underside of the vehicle using the jack and tools provided.

Common locations and access methods

• In the trunk: Lift the trunk lid and then lift the floor panel or cover to reveal the spare tire, jack, and tools. 
• Under the rear of the vehicle: Open the rear hatch or tailgate. The spare tire is usually suspended underneath, and you'll need to use the jack and lug wrench to lower it through an access hole. 
• In the truck bed: Some models, like the Chevrolet Colorado ZR2, have a bed-mounted vertical spare tire carrier. 

Steps to access the spare tire

1. Open the rear hatch, trunk, or tailgate. 
2. Lift the cargo floor cover or locate the access point for the tire mechanism. 
3. Remove any styrofoam inserts or sub-compartments that are securing the tire and tools. 
4. Unscrew any hold-down bolts or wing nuts to free the spare tire. 
5. Use the provided tools to lower the spare tire or remove it from its storage location.

Important tips

• Always consult your vehicle's owner's manual for the most accurate information and specific instructions. 
• Ensure you have the necessary tools, which are usually included with the spare tire, before you begin. 
• When changing a tire, park on a firm, level surface away from traffic and engage the parking brake. 

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. 

What to do if I have a flat tire and no spare?

If you have a flat tire and no spare, your best options are to call for professional roadside assistance or use a tire repair kit. You can also try to temporarily inflate the tire with a portable compressor if the damage is minor, which may allow you to drive slowly to a repair shop.
 
Immediate actions

• Pull over to a safe location. Turn on your hazard lights and, if possible, place warning triangles or cones behind your vehicle to alert other drivers.
• Assess the damage. Look to see if it's a simple puncture or more severe damage, and note if there is any air left in the tire. 

Options for a flat tire with no spare

• Use a tire repair kit. Many newer cars come with a kit instead of a spare tire. This typically includes a can of sealant and a portable air compressor to inflate the tire. 
  • Follow the kit's instructions to inject sealant into the tire and then inflate it to a temporary pressure. This is a temporary fix to get you to a repair shop. 
• Call roadside assistance. Contact your insurance provider or a service like AAA for help. They can tow your vehicle to a nearby mechanic or provide on-site repair if possible. 
• Try inflating with a portable compressor. If the tire has air but is low, use a portable compressor (plugs into the car's cigarette lighter) to inflate it enough to drive to a shop. Do not drive if the tire is completely flat, as this can cause permanent damage. 
• Take the wheel to a shop. If you have the tools but no spare, you can remove the flat wheel, take it to a tire shop for repair or replacement, and then bring the new or repaired wheel back to your car. 

What to do after the immediate fix

• Visit a professional. Whether you used a repair kit or inflated the tire, your next step should be to get to a tire shop for a proper repair or new tire as soon as possible. 
• Inform the mechanic. If you used a sealant, let the shop know so they can be prepared when they take the tire off the rim.
