When it comes to high-performance driving, the RoadOne Cavalry 245/40R20 represents the pinnacle of engineering for the modern road. This isn’t just a tire; it is the critical interface between your high-torque vehicle and the asphalt. Designed for enthusiasts who refuse to compromise, the Cavalry series provides the aggressive “low-profile” look that defines modern luxury vehicles while delivering the all-weather safety necessary for daily commuting.
Whether you are carving through mountain passes or navigating a rain-slicked highway, the RoadOne Cavalry 245/40R20 is built to keep you planted. Its wide footprint and rigid construction are specifically tuned for vehicles that require a higher load capacity and a higher speed rating, ensuring that your car’s performance potential is never throttled by its rubber.
The 245/40R20 fitment is naturally wider and lower than standard passenger tires. This design is intentional. The increased section width (245mm) provides a massive contact patch, which translates directly into better lateral grip. When you turn the steering wheel, the RoadOne Cavalry responds with immediacy, reducing the “squirm” often felt in tires with taller sidewalls.
The asymmetric tread design features reinforced outer shoulder blocks. These blocks are designed to remain rigid under heavy cornering loads, preventing the tire from deforming when you take a sharp turn. This results in predictable, “on-rails” handling that enhances driver confidence at every turn.
While many performance tires struggle when the temperature drops or the clouds gather, the RoadOne Cavalry thrives. It utilizes an advanced silica-infused rubber compound that remains pliable in cold temperatures while providing “sticky” grip on hot summer pavement.
Hydroplaning Resistance: Four wide, deep circumferential grooves run the length of the tire. These act as high-volume water pumps, channeling surface water away from the contact patch to prevent hydroplaning in heavy rain.
Winter Siping: Unlike summer-only performance tires, the Cavalry is equipped with high-density lateral sipes. These microscopic biting edges allow the tire to “grab” onto light snow and slush, providing the traction you need to get home safely when the seasons change unexpectedly.
One of the most common complaints regarding 20-inch performance tires is the increase in road noise and a “harsh” ride. RoadOne has addressed these concerns head-on with the Cavalry’s internal architecture and tread geometry.
RoadOne engineers utilized computer-optimized pitch variation technology to design the Cavalry’s tread. By slightly varying the size and shape of the tread blocks, the tire creates varying sound frequencies as it rotates. These frequencies effectively cancel each other out, significantly reducing the “hum” or “drone” that often permeates the cabin of luxury vehicles on the highway.
Despite its thin 40-series profile, the RoadOne Cavalry is built with a high-tensile steel belt package and a flexible carcass. This allows the tire to act as a primary shock absorber, soaking up the sharp jolts from expansion joints and small potholes before they reach your vehicle’s suspension. The result is a ride quality that feels connected to the road but never punishing.

Understanding the technical aspects of the RoadOne Cavalry 245/40R20 ensures that you are selecting a tire that meets your vehicle’s specific safety requirements.
Many 20-inch fitments require an “Extra Load” (XL) rating. The RoadOne Cavalry 245/40R20 is an XL tire, meaning it is built with a reinforced internal structure capable of handling higher inflation pressures and heavier loads than a standard (SL) tire. With a load index of 99, this tire can support 1,709 lbs per tire. This is essential for modern electric vehicles (EVs) and heavy luxury sedans that carry significant battery or chassis weight.
The “W” rating signifies that this tire has been tested to perform safely at speeds up to 168 mph. While you will likely never reach these speeds, the rating is a testament to the tire’s heat management capabilities. High-speed-rated tires are constructed to stay cool under stress, which directly improves safety during long-distance highway driving and high-ambient-temperature summer days.
Tires are an investment, and the RoadOne Cavalry is designed to provide a high return on that investment. Performance tires are notorious for wearing out quickly, often lasting only 20,000 to 30,000 miles. RoadOne defies this trend by offering a 50,000-mile manufacturer’s mileage warranty.
The secret to the Cavalry’s longevity lies in the chemical bond of the rubber. By blending silica with high-grade carbon black, the tread achieves high abrasion resistance. This means the rubber “sloughs off” much slower than traditional performance compounds, allowing you to enjoy that “new tire feel” for years rather than months.
The tire’s internal structure is designed to keep the tread flat against the road, even during aggressive driving. This prevents “cupping” or “feathering”—uneven wear patterns that cause vibration and shorten the life of the tire. By maintaining a consistent footprint, the RoadOne Cavalry ensures that every millimeter of the 10/32” tread depth is utilized efficiently.
To ensure you reach the full 50,000-mile potential of your RoadOne Cavalry 245/40R20 tires, we recommend following these maintenance guidelines:
Monitor Tire Pressure: Because these are Extra Load (XL) tires, they may require higher PSI than your previous set. Check the door placard of your vehicle and adjust monthly.
Regular Rotations: Have your tires rotated every 5,000 to 7,500 miles. This is especially important for rear-wheel-drive vehicles to prevent the drive tires from wearing faster than the steering tires.
Alignment Checks: Large 20-inch wheels are susceptible to alignment issues if you hit a curb or a large pothole. A slight misalignment can ruin a performance tire in just a few thousand miles.
Cleaning: Use only mild soap and water to clean your sidewalls. Harsh petroleum-based tire shines can actually degrade the UV protectants in the rubber over time.
The RoadOne Cavalry 245/40R20 is more than just a budget-friendly alternative to big-name brands. It is a highly engineered, all-season performance tire that delivers on its promises. From the 168-mph speed rating to the 50,000-mile warranty, every aspect of this tire is designed to provide peace of mind and driving excitement.
Upgrade your vehicle today with a tire that offers the perfect synergy of style, safety, and stamina.
