This post explains how to understand the specifications of this tire, how to install it properly, and how to maintain it for the best results.

Understanding the Tire Specifications
The tire size and code "235/40R18 ARYO GRNDSPTAS 95YXL" contains important information about the tire's dimensions, load capacity, speed rating, and construction.
235: This number represents the tire width in millimeters. A width of 235 mm means the tire is wide enough to provide good road contact and stability.
40: This is the aspect ratio, the height of the tire's sidewall as a percentage of the width. A 40% aspect ratio indicates a relatively low profile, which improves handling and cornering.
R18: The "R" stands for radial construction, the most common type of tire design. The number 18 indicates the diameter of the wheel rim in inches that the tire fits.
95YXL: This code shows the load index and speed rating. A load index of 95 means the tire can carry up to 1,521 pounds (690 kg) per tire. The "Y" speed rating means the tire is safe up to 186 mph (300 km/h). The "XL" stands for extra load, meaning the tire can handle more weight than a standard tire of the same size.
Knowing these details helps you confirm that the tire matches your vehicle's requirements and driving style.
How to Install the Arroyo Grand Sport A/S 235/40R18 Tires
Proper installation ensures the tire performs well and lasts longer. Follow these steps for a safe and effective installation:
Check Compatibility
Verify that the tire size 235/40R18 matches your vehicle's specifications. Consult your owner's manual or the tire placard on the driver’s door frame.
Inspect the Tires
Before installation, look for any visible defects such as cuts, bubbles, or uneven tread.
Mounting the Tires
Use a professional tire mounting machine to avoid damaging the tire or rim. The tire should be mounted so the directional tread pattern (if any) faces the correct direction.
Balancing the Tires
After mounting, balance the tires to prevent vibrations and uneven wear. This step requires specialized equipment.
Proper Inflation
Inflate the tires to the recommended pressure, usually found in the vehicle manual or on the tire placard. Over- or under-inflation can affect handling and tire life.
Alignment Check
After installation, have your vehicle’s wheel alignment checked. Proper alignment reduces tire wear and improves safety.
Maintaining Your Arroyo Grand Sport A/S Tires
Maintaining your tires extends their life and keeps your driving safe. Here are practical tips for care:
Regular Pressure Checks
Check tire pressure at least once a month and before long trips. Use a reliable gauge and adjust pressure to the recommended level.
Rotate Tires
Rotate your tires every 5,000 to 7,000 miles to ensure even wear. This practice balances the wear patterns between front and rear tires.
Inspect Tread Depth
Use a tread depth gauge or the penny test to monitor tread wear. Replace tires when tread depth reaches 2/32 of an inch to maintain traction.
Avoid Harsh Driving
Sudden stops, fast cornering, and rapid acceleration increase tire wear. Drive smoothly to preserve your tires.
Keep Tires Clean
Remove dirt and debris regularly. Clean tires with mild soap and water to prevent rubber degradation.
