When you drive a vehicle equipped with 18-inch wheels, you expect a certain level of feedback and agility from your tires. The Roadone Cavalry 245/45R18 is designed specifically to meet those expectations. Whether you are piloting a BMW 5-Series, a Honda Accord Sport, or a Cadillac CTS, the 245/45R18 fitment is a critical component of your vehicle’s suspension geometry.
Roadone, utilizing global engineering standards, has developed the Cavalry line to bridge the gap between expensive “big-name” tires and low-quality budget options. This tire offers a premium silica compound and a reinforced internal structure, ensuring that your car’s handling potential is fully realized without a premium price tag.
The Roadone Cavalry 245/45R18 isn’t just an all-season tire; it is a performance-oriented tool. Its design focuses on three pillars of driving: stability, steering response, and stopping power.
Asymmetric Tread Design: The tread is divided into distinct zones. The outer shoulder features large, solid tread blocks that resist deformation during hard cornering, providing “on-rails” stability. The inner zone is optimized with high-density sipes to bite into wet or frosty pavement.
Sharp Steering Response: Thanks to a rigid center rib, the Cavalry offers an immediate “on-center” feel. When you move the steering wheel, the tire reacts instantly, reducing the lag often found in standard touring tires.
Wet Weather Mastery: Safety in the rain is paramount. Four wide, longitudinal grooves work in tandem to pump water away from the contact patch at high speeds. This drastically reduces the risk of hydroplaning and maintains a solid connection to the road during heavy summer storms.
UHP tires are often known for being noisy, but Roadone has mitigated this through advanced acoustic engineering. The Cavalry 245/45R18 features a variable-pitch tread sequence. By staggering the size of the tread blocks, the tire breaks up the harmonic sound waves that typically cause a “droning” noise on the highway. This ensures that even with the windows down, your driving experience remains refined and peaceful.
The 245/45R18 size often carries a heavier load than smaller tires, which is why Roadone has reinforced this model with an Extra Load (XL) rating.
Standard tires (SL) are often insufficient for modern electric vehicles or heavy luxury sedans. The Roadone Cavalry’s XL rating means the tire is built with reinforced internal belts, allowing it to handle higher inflation pressures and greater weight. This reinforcement prevents sidewall “bulging” and ensures the tire maintains its optimal shape even when the vehicle is fully loaded with passengers or luggage.
High-performance tires are notorious for wearing out quickly. However, Roadone breaks this trend by offering a 50,000-mile manufacturer’s limited treadwear warranty. This is achieved through the use of an abrasion-resistant silica compound that slows the rate of rubber loss during daily driving. When you choose the Cavalry, you are choosing a tire that stays on your car longer, providing better value over the lifetime of the vehicle.

On the sidewall of the Roadone Cavalry 245/45R18, you will find the service description 100W. This is the tire’s “resume,” detailing exactly what it can handle.
A load index of 100 means each tire can support 1,764 pounds. With four tires, your vehicle has a total capacity of 7,056 pounds. This is particularly important for the 245/45R18 size, which is often used on modern crossovers and EVs that carry significant battery weight. The 100-index rating ensures that the tire won’t suffer from heat-related failure under load.
A W speed rating is one of the highest available for street tires, certifying the tire for speeds up to 168 mph.
Safety First: While you will not be driving at these speeds, a W-rated tire is built to much tighter tolerances than a standard tire.
Heat Management: W-rated tires are designed to dissipate heat extremely efficiently. In high-temperature climates, this prevents the rubber from softening too much, which maintains your grip and safety during long highway stretches.
To ensure your Roadone Cavalry 245/45R18 reaches the 50,000-mile mark, follow these essential maintenance steps:
Monitor PSI Regularly: Because this is an XL tire, it may require a higher cold inflation pressure (typically 35–38 PSI) than standard tires. Check your vehicle’s door placard for the specific recommendation.
Rotation is Key: Front tires on performance sedans handle the bulk of the braking and steering torque. Rotate your tires every 5,000 miles to ensure even tread wear across all four corners.
Alignment Checks: The 45-series aspect ratio is sensitive to alignment. If your vehicle pulls to one side, have the alignment checked immediately to prevent “feathering” the tread.
Tread Depth Checks: Use a tread depth gauge to monitor your 10/32″ starting depth. If you reach 2/32″, the tire is legally worn out and must be replaced for safety.
The Roadone Cavalry 245/45R18 offers everything a modern driver needs: the aggressive look of a UHP tire, the safety of an all-season compound, and the longevity of a 50,000-mile warranty. Whether you are navigating your daily commute or enjoying a weekend drive on twisting backroads, the Cavalry provides the reliability and performance your vehicle deserves.
Stop overpaying for big-brand names and start driving on a tire engineered for the real world.
