Subaru Ascent: Does It Have a Full Size Spare Tire? Insights on Features and Options

The Subaru Ascent does not include a full-size spare tire. Weight limitations and space constraints near the exhaust prevent this. Owners can buy an OEM spare wheel, but the manual warns against placing a full-size tire under the vehicle. Smaller temporary spare tires are available, but replace them quickly for better tire performance and safety.

The Subaru Ascent offers several features that enhance comfort and safety. It includes standard all-wheel drive, ample cargo space, and advanced driver assistance technologies. Moreover, the Ascent provides three rows of seating, accommodating up to eight passengers, which makes it a practical choice for families.

For those seeking additional security, Subaru offers an optional roadside assistance program. This can ease concerns related to tire issues while on the road. It’s important to consider these factors when evaluating the Subaru Ascent’s suitability for your needs.

In summary, while the Subaru Ascent lacks a full-size spare tire, its features cater to a range of driving conditions. Understanding these aspects can help potential buyers make informed decisions about their vehicle preferences. Next, let’s explore the various trim levels and available packages for the Subaru Ascent.

Does the Subaru Ascent Have a Full Size Spare Tire?

No, the Subaru Ascent does not come with a full-size spare tire. Instead, it includes a compact temporary spare tire.

This decision is common among many manufacturers to save space and weight. A compact spare tire is lighter and takes up less room in the vehicle. However, it typically has limitations in speed and distance compared to a full-size spare. This can affect drivers in an emergency situation where the full-size spare would provide more reliability and ease of handling.

What Size of Spare Tire Does the Subaru Ascent Come With?

The Subaru Ascent comes with a temporary spare tire, also known as a “donut” tire.

  1. Temporary spare tire
  2. Full-size spare tire option (aftermarket)
  3. Roadside assistance availability
  4. Tire repair kits

The following sections provide detailed insights into each of these points regarding the Subaru Ascent’s spare tire options.

  1. Temporary Spare Tire: The Subaru Ascent includes a temporary spare tire as part of its standard equipment. This type of tire is smaller and lighter than a regular tire, which helps save space in the vehicle. It is designed for short-term use and typically has limited speed and distance capabilities. Subaru recommends using this tire for no longer than 50 miles and not exceeding 50 miles per hour. The size of the temporary spare tire for the Ascent is designed to fit over a variety of rim sizes while ensuring compatibility with the vehicle’s wheel alignment.

  2. Full-Size Spare Tire Option (Aftermarket): While the Ascent does not come with a full-size spare tire, owners have the option to purchase one aftermarket. A full-size spare provides better support and performance over long distances compared to a temporary spare. It allows for more extended use, typically matching the specifications of the existing tires. However, this option may require additional storage consideration within the vehicle, as it takes up more space than the stock temporary spare.

  3. Roadside Assistance Availability: Subaru offers a roadside assistance program with new Ascent vehicles, enhancing convenience for owners who experience a flat tire. Roadside assistance can include services such as tire changing, towing, and emergency fuel delivery. This service is often a reassuring option for drivers who prefer not to handle tire changes themselves. It is especially useful when the temporary spare is in use, ensuring that drivers do not have to travel far on a limited-use tire.

  4. Tire Repair Kits: The Subaru Ascent may also come equipped with a tire repair kit, which is an alternative for fixing minor tire punctures. These kits typically include sealant and an air compressor, providing a temporary solution to keep drivers on the road. However, they are not a substitute for a spare tire, and their effectiveness depends on the size and location of the puncture. While repair kits are convenient for quick fixes, they may not be viable for larger damages or complete tire failures.

In summary, the Subaru Ascent features a temporary spare tire as standard equipment, with options for aftermarket full-size spares, roadside assistance, and tire repair kits available for owners who seek additional support.

Why Should Vehicle Owners Consider a Full Size Spare Tire?

Vehicle owners should consider a full-size spare tire for several important reasons. A full-size spare provides better performance and safety compared to a smaller, temporary spare. It allows for full-speed travel and maintains balanced handling, which can be crucial in emergencies.

The National Highway Traffic Safety Administration (NHTSA) defines a full-size spare tire as a tire that matches the size and specifications of the vehicle’s original equipment tires (NHTSA, 2021). This ensures that the spare can be used for extended periods without jeopardizing safety or performance.

There are several underlying reasons vehicle owners should prioritize a full-size spare tire. First, it allows for immediate replacement of a damaged tire without limiting the vehicle’s speed or handling. Second, full-size spares support proper alignment, preventing wear on other tires and reducing the risk of accidents. Third, the confidence of having a fully functional tire can ease travel anxiety.

Technical terms relevant to this discussion include “temporary spare” and “full-size spare.” A temporary spare, also known as a “donut tire,” is smaller and lighter than a standard tire, designed for temporary use only. It typically restricts speed to 50 mph and is shorter in diameter, which can affect vehicle handling.

The mechanism behind the necessity of a full-size spare involves the dynamics of vehicle performance. A full-size spare aligns with the other tires, ensuring stability and grip on the road. In contrast, a temporary spare may lead to uneven handling or loss of traction, particularly in adverse weather conditions.

Specific conditions that contribute to the issue of tire failure include road hazards, such as potholes or debris, as well as natural wear and tear. For instance, driving in adverse conditions like heavy rain or snow increases the likelihood of encountering obstacles that can damage tires. Using a full-size spare in such situations provides assurance and maintains safe driving conditions, particularly when a swift replacement is necessary.

What Are the Benefits of a Full Size Spare Tire Over a Compact Spare?

The benefits of a full-size spare tire over a compact spare tire include better handling, improved safety, increased durability, and extended usability.

  1. Better handling
  2. Improved safety
  3. Increased durability
  4. Extended usability

Having considered these benefits, it is essential to explore each aspect in detail to understand their significance.

  1. Better handling: A full-size spare tire provides better handling compared to a compact spare tire. It matches the size and load capacity of the other tires on the vehicle. This similarity ensures consistent grip and traction, which is crucial for maintaining control, especially in adverse weather conditions. According to a study by Tire Rack, vehicles equipped with full-size tires display less understeer and oversteer, giving drivers more confidence while navigating sharp turns or emergency stops.

  2. Improved safety: The use of a full-size spare tire enhances safety during a tire failure scenario. Drivers can have peace of mind knowing they can replace a flat tire with one that retains the same specifications as the remaining tires. This uniformity decreases the chance of a blowout or loss of stability. The National Highway Traffic Safety Administration (NHTSA) emphasizes that consistent tire performance is vital in preventing accidents, particularly at high speeds.

  3. Increased durability: Full-size spare tires are typically more durable than compact spares. They are designed to withstand greater wear and tear, making them suitable for longer distances. The Rubber Manufacturers Association indicates that full-size tires can often be used for a full range of driving conditions. In contrast, compact spares are generally intended for short-term use and lower speeds, with limitations on mileage.

  4. Extended usability: Full-size spare tires offer extended usability beyond an immediate replacement. When a flat occurs, drivers can continue using a full-size spare without concern for speed or distance restrictions. This usability is particularly beneficial in remote areas where tire repair services may not be readily available. According to the American Automobile Association (AAA), having a reliable spare tire can save time and money by reducing the need for roadside assistance.

In summary, full-size spare tires greatly enhance vehicle handling, safety, durability, and usability in a variety of driving situations.

How Does the Spare Tire of the Subaru Ascent Compare to Other SUVs on the Market?

The spare tire of the Subaru Ascent is a compact temporary tire, also known as a “donut” tire. This design differs from many other SUVs on the market that often come with either a full-size spare or a similar temporary tire. The compact spare tire is lighter and takes up less space, making it easier to store. However, it is not intended for long-distance driving or high speeds. This limitation means drivers may need to replace a flat tire with a full-size tire sooner than they would with SUVs that offer a full-size spare. In contrast, SUVs like the Toyota Highlander or Ford Explorer often include a full-size spare, offering better peace of mind for those who frequently drive in remote areas. Overall, while the Subaru Ascent’s spare tire offers practical storage advantages, it may not provide the same level of confidence as the full-size spare options found in other SUVs.

Are There Any Notable Alternatives to the Full Size Spare Tire for the Subaru Ascent?

Yes, there are notable alternatives to the full-size spare tire for the Subaru Ascent. These alternatives include a compact spare tire and a tire repair kit. Each option has specific advantages that may suit different drivers’ needs.

The compact spare tire is smaller and lighter than a full-size tire. It is designed for temporary use and can fit in the Subaru Ascent’s spare tire well. In contrast, a tire repair kit typically includes sealant and an air compressor to fix minor punctures without changing the tire. While both options aim to keep the vehicle on the road after a tire incident, the compact spare allows for higher speed and distance, whereas the repair kit is limited by the type and severity of the damage.

One positive aspect of the compact spare is its ease of storage and lower weight. For example, a compact spare can take up less trunk space, which is valuable for families or those who carry a lot of cargo. Additionally, using a repair kit can save weight and space while eliminating the need for a spare tire altogether. According to a study by the Tire Industry Association in 2021, many drivers appreciate the convenience of tire repair kits due to lower maintenance and the absence of an extra tire.

On the negative side, compact spare tires are not suitable for long-distance travel. They typically have a speed limit of around 50 mph and should only be used until a full-size tire can be obtained. Repair kits can fail if the damage is severe, potentially leaving drivers stranded. A report by the National Highway Traffic Safety Administration (NHTSA) in 2020 indicated that improper use of tire repair kits could lead to further tire damage or safety issues on the road.

For Subaru Ascent owners, specific considerations include assessing driving habits and preferences. If frequent long-distance travel is common, a compact spare could be a better option to maintain mobility. Conversely, if space-saving is a priority and driving conditions are generally safe, a tire repair kit may be adequate. It is essential to review the owner’s manual and understand the limitations and proper usage of whichever alternative is chosen.

What Should You Do If Your Subaru Ascent Lacks a Full Size Spare Tire?

If your Subaru Ascent lacks a full-size spare tire, consider the following options to address the issue.

  1. Use the provided temporary spare tire.
  2. Purchase a full-size spare tire compatible with your Ascent.
  3. Carry a tire repair kit as an alternative.
  4. Consider roadside assistance services.
  5. Explore aftermarket solutions for additional storage.

Ultimately, determine the best approach based on your travel habits and concerns about tire emergencies.

1. Use the Provided Temporary Spare Tire:

Using the provided temporary spare tire allows you to replace a flat tire effectively, even though it is smaller than a full-size tire. Temporary spares are generally lighter and easier to handle. However, they are designed for short-term use and should not exceed a certain speed, often around 50 mph, which limits their functionality. According to Subaru, a temporary spare is designed to get you safely to a service station.

2. Purchase a Full-Size Spare Tire Compatible with Your Ascent:

Purchasing a full-size spare tire that fits your Subaru Ascent is a practical option. A full-size spare matches your vehicle’s regular tires in size and performance characteristics. This option provides peace of mind for longer trips where a flat tire might leave you stranded. Many car enthusiasts recommend this practice because it maintains handling and safety features. When buying a tire, refer to the vehicle’s owner manual to ensure compatibility.

3. Carry a Tire Repair Kit as an Alternative:

Carrying a tire repair kit offers a proactive approach to addressing minor tire issues. Repair kits typically include sealant and a compressor to fix small punctures quickly. This option is particularly useful if you frequently drive in remote areas. However, it is not a substitute for a spare and may not work effectively for larger damages. According to Consumer Reports, a tire repair kit can be a lifesaver, especially if you enjoy off-roading or traveling off the beaten path.

4. Consider Roadside Assistance Services:

Opting for roadside assistance services ensures professional help is available whenever you encounter a tire issue. These services provide support such as tire changes or towing if necessary. Many automobile clubs and insurance companies offer roadside assistance as part of their policies. This option can be especially beneficial if you feel uneasy handling tire problems alone. Some studies indicate that about 70% of drivers benefit from having a roadside assistance plan.

5. Explore Aftermarket Solutions for Additional Storage:

Exploring aftermarket solutions can enhance storage for a full-size spare tire if your vehicle lacks the necessary space. Some accessories allow you to mount a spare tire on the rear of the vehicle or in the trunk without compromising your cargo area. While this option provides extra protection, it requires careful installation and may affect your vehicle’s appearance and aerodynamics. Always consult with a trusted automotive professional before making modifications to your vehicle.

Where Can You Purchase a Full Size Spare Tire for Your Subaru Ascent?

You can purchase a full-size spare tire for your Subaru Ascent at several locations. First, check with authorized Subaru dealerships. They often sell OEM (Original Equipment Manufacturer) tires that match your vehicle’s specifications. Next, consider tire retailers such as Discount Tire or Tire Rack. These retailers offer a variety of full-size tires for different vehicle makes and models. Additionally, you can explore online marketplaces like Amazon or eBay, which may have new or used full-size spare tires available. Finally, local tire shops and automotive supply stores may also stock compatible full-size spare tires.
