In addition to P-Metric and LT tires, there are also a variety of specialty tires that come with their own designations. One common designation you may see is OWL, which stands for Outlined White Letters.
These tires have white letters on the sidewall that are outlined in black, giving them a distinctive look. RWL, or Raised White Letters, are similar to OWL tires, but the white letters are raised rather than outlined.
Another specialty tire designation you may come across is WSW, which stands for White Sidewall. These tires have a white stripe on the sidewall, giving them a classic look that is often associated with vintage cars.
It’s important to note that these specialty tires are often more expensive than standard tires, so they may not be the best choice for everyone. However, if you’re looking for a unique look for your vehicle, they can be a great option.
Other Designations
In addition to the tire types and designations mentioned above, there are a variety of other designations you may come across when shopping for tires. Some common designations include:
- Radial: This refers to the construction of the tire, which features radial plies that run perpendicular to the tread. Radial tires are the most common type of tire on the market today.
- Reinforced: This designation indicates that the tire has additional reinforcement to help it handle heavy loads.
- Extra Load/Standard Load: These designations indicate the weight capacity of the tire. Extra Load tires are designed to handle heavier loads than Standard Load tires.
- M+S: This stands for Mud and Snow, and indicates that the tire is designed to perform well in muddy and snowy conditions.
By understanding these tire types and designations, you can make an informed decision when shopping for tires that will meet your specific needs.
Performance and Safety Features
BSW tires are designed to provide drivers with a safe and comfortable ride while also delivering performance and durability. In this section, we will discuss the various performance and safety features of BSW tires.
Traction, Treadwear, and Temperature Ratings
Traction, treadwear, and temperature ratings are important factors to consider when choosing BSW tires. Traction ratings indicate the tire’s ability to grip the road in wet or slippery conditions. Treadwear ratings indicate the expected lifespan of the tire, while temperature ratings indicate the tire’s ability to withstand heat buildup during prolonged use.
BSW tires typically have excellent traction ratings due to their unique tread patterns and rubber compounds. They also have high treadwear ratings, making them a durable choice for drivers. Additionally, BSW tires are designed to withstand high temperatures, making them a safe choice for drivers who frequently drive in hot climates.
Load Capacity and Speed Ratings
Load capacity and speed ratings are also important factors to consider when choosing BSW tires. Load capacity ratings indicate the maximum weight that a tire can safely carry, while speed ratings indicate the maximum speed that a tire can safely handle.
BSW tires typically have high load capacity ratings, making them a safe choice for drivers who frequently carry heavy loads. They also have high speed ratings, making them a good choice for drivers who frequently drive at high speeds.
Maintenance and Care for Longevity
To ensure the longevity of BSW tires, proper maintenance and care are essential. Here are some tips to help keep BSW tires in good condition:
Checking Tire Pressure and Load
Maintaining proper inflation pressure is important for BSW tires. Underinflated tires can cause poor handling and fuel economy, while overinflated tires can cause uneven wear and a harsh ride. The maximum air pressure for BSW tires is usually indicated on the sidewall.
It is important to check the inflation pressure regularly, at least once a month, using a tire pressure gauge. The recommended inflation pressure can be found in the owner’s manual or on a sticker located on the driver’s side door jamb. The pressure should be checked when the tires are cold, meaning the vehicle has not been driven for at least three hours.
In addition to checking inflation pressure, it is important to check the load capacity of the tires. Overloading the vehicle can cause excessive wear and damage to the tires. The load capacity can be found on the sidewall of the tire.
Understanding Tire Wear and Aging
Tire age and treadwear rating are important factors to consider when maintaining BSW tires. Tires that are over six years old, regardless of tread depth, should be replaced due to aging and deterioration. The treadwear rating can be found on the sidewall of the tire and indicates how long the tire is expected to last.
It is important to regularly check the tire tread depth using a tread depth gauge. The minimum legal tread depth is 2/32 of an inch, but it is recommended to replace the tires at 4/32 of an inch for safety reasons.
Tire wear can also be an indication of other problems with the vehicle, such as misalignment or suspension issues. It is recommended to have the tires inspected by a professional if there is uneven wear or unusual tire wear patterns.
