Your vehicle is a symbol of freedom, a tool that unlocks a world of adventure, and a companion on your daily journeys. Your converted SUV from ATC Mobility is built to serve your independence, and every component plays a crucial role in its performance and safety.
While the innovative hydraulic lift system and accessible controls get a lot of attention (with good reason), the tires are where your vehicle truly connects with the road. The right set of tires makes a world of difference in handling, comfort, and capability. That is why choosing the right tires for your wheelchair-accessible SUV is a decision that directly impacts every drive you take.
A standard SUV is already a substantial vehicle, but a wheelchair-accessible conversion adds unique considerations. The hydraulic lift system, reinforced flooring, and other modifications add weight, not to mention the user’s wheelchair. This additional weight is not always distributed evenly, which changes the vehicle’s center of gravity and handling dynamics.
Your tires must be capable of supporting this increased load safely. They also need to provide the stability and traction you rely on, whether you are navigating a slick city street or heading out on a gravel road for a weekend escape. The right tires work in harmony with your vehicle’s suspension to deliver a smooth, controlled ride.
One of the most critical factors you should look out for is the tire’s load index. This number, found on the tire’s sidewall, tells you the maximum weight each tire can safely support when properly inflated.
Given the added weight of the conversion, you will likely need tires with a higher load index than the original factory recommendation. An “XL” or “Extra Load” rating on a tire indicates it has a reinforced construction to handle heavier loads and higher inflation pressures.
Next to the load index, you will find a letter representing the speed rating. This indicates the maximum speed the tire can sustain.
While you may not plan on testing these limits, a higher speed rating often correlates with better handling and stability. Tires designed for higher speeds typically feature construction elements that enhance grip and responsiveness.
Types of Tires for Every JourneyThe type of driving you do most often will guide you toward the best tire category for your needs. Each type offers a different balance of performance characteristics.
For many drivers, all-season tires are the perfect option. They are the versatile workhorses of the tire world. Their design performs well in a wide range of conditions, including wet roads and light snow.
All-season tires offer a comfortable ride, good tread life, and reliable year-round traction. If your adventures are mostly on paved roads with occasional encounters with varied weather, all-season tires are a dependable choice.
If your definition of freedom includes leaving the pavement behind, all-terrain (A/T) tires are your ticket to exploration. These tires feature a more aggressive tread pattern with larger blocks and deeper voids. This design provides the extra grip needed to hold onto dirt, gravel, mud, and rocky surfaces.
While they may be slightly noisier on the highway than all-season tires, modern A/T tires offer a great compromise between off-road capability and on-road comfort. These tires are a popular choice for a wheelchair-accessible luxury SUV built for adventure.
For those living in areas with harsh winters, dedicated winter tires are a valuable safety investment. They are made from a special rubber compound that stays flexible in freezing temperatures, allowing the tire to maintain its grip on ice and snow.
The tread patterns are specifically designed to channel away slush and bite into packed snow. The difference in braking and handling on a snowy road between all-season and winter tires is remarkable, providing confidence when the weather is at its worst.
Beyond the type, several other factors contribute to a tire’s performance and longevity. Paying attention to these details will help you maximize the benefits of your investment.
The treadwear grade provides a comparative indication of a tire’s expected lifespan. A higher number suggests a longer tread life. Keep in mind that your driving style, road conditions, and proper maintenance have a large impact on how long your tires actually last.
The sidewall is the part of the tire between the tread and the wheel. For those who venture off-road, a tire with a reinforced or more durable sidewall is a wise choice. This extra toughness helps protect against cuts, punctures, and abrasions from rocks and other trail hazards.
Your vehicle’s TPMS is a critical safety feature. It alerts you when one or more of your tires is under-inflated. Proper inflation is essential for safety, fuel economy, and tire longevity, especially on heavier converted vehicles.
Always inflate your tires to the pressure recommended by the conversion manufacturer, which may be different from the pressure listed on the vehicle’s door jamb given the adjusted weight distribution. Check your tire pressure regularly, as temperature changes can cause it to fluctuate.
Some vehicles come equipped with run-flat tires, which allow you to continue driving for a limited distance after a puncture. This can provide peace of mind, eliminating the immediate need to change a tire in a potentially unsafe location.
However, they often give a harsher ride and can be more costly to replace. The alternative is a standard tire paired with a good-quality tire repair and inflator kit. This kit can quickly seal a small puncture and re-inflate the tire, getting you back on the road and to a repair shop.
The Importance of Alignment and RotationProper vehicle alignment is crucial for any car, but it is especially important for a modified SUV. An alignment makes certain that all four tires are pointing in the right direction, parallel to each other, and perpendicular to the ground. This prevents uneven tire wear and improves handling.
Regular tire rotation is equally important. This involves moving your tires to different positions on the vehicle at set intervals. Due to the unique weight distribution of a converted SUV, some tires may wear out faster than others. Rotating them helps them wear evenly, extending the life of the set and maintaining balanced handling.
Your journey is uniquely yours, and the vehicle that takes you there should be perfectly equipped for the path ahead. The tires you select are the foundation of your vehicle’s safety, comfort, and capability.
By understanding the demands of your modified SUV and matching them with the right features, you can drive with confidence, knowing you are ready for whatever the road brings. Taking the time to choose the right tires for your wheelchair-accessible SUV is an investment in your freedom and independence.
