Toyo proxes R1R Toyo tires

The Toyo Proxes R1R is a high-performance summer tire from Toyo Tires, designed specifically for sporty driving, offering excellent handling, grip, and responsiveness in dry and wet conditions. These tires are often favored by enthusiasts for use on high-performance street cars and for occasional track use, thanks to their combination of street practicality and track-ready performance.

Key Features of the Toyo Proxes R1R:

1. Aggressive Tread Design:
   • The Proxes R1R has a distinctive, aggressive tread pattern designed for maximum grip on dry roads. Its wide outer shoulder blocks and continuous center rib provide enhanced cornering stability and precise steering response.
2. High-Grip Compound:
   • Toyo uses a high-grip silica-reinforced compound in the R1R, which offers excellent traction in both dry and wet conditions. This compound helps provide impressive levels of grip, particularly in dry weather, where the tire excels.
3. Wet Performance:
   • While the Proxes R1R is a summer tire, it performs well in wet conditions due to its wide grooves and directional tread design. These features help evacuate water from the contact patch, reducing the risk of hydroplaning and improving wet traction.
4. Autocross and Track Capability:
   • The R1R is known for being an ideal tire for autocross and track days, as it can deliver strong lateral grip, quick turn-in response, and high-speed cornering ability. However, it is not a dedicated racing slick, so it still offers enough comfort and versatility for street driving.
5. Stiff Sidewalls:
   • The tire features reinforced sidewalls, which contribute to better cornering and steering response. This characteristic makes the Proxes R1R particularly suited to cars with sporty suspensions that can take full advantage of its handling capabilities.
6. Treadwear:
   • The R1R is a high-performance summer tire, so its treadwear rating (UTQG) is relatively low, typically around 140-200, meaning it is not designed for long-term durability. This is normal for high-grip tires, which tend to wear faster due to their soft rubber compounds.
7. Ideal for Performance Enthusiasts:
   • Drivers who enjoy spirited driving on twisty roads, participate in autocross events, or do light track days will find the Toyo Proxes R1R to be a great match for their needs. It provides a balance between street and track performance.

Pros of the Toyo Proxes R1R

• Exceptional Dry Grip: The tire’s high-grip compound and aggressive tread design give it excellent grip in dry conditions, making it ideal for performance driving.
• Responsive Steering: Due to its stiff sidewalls and tread design, the Proxes R1R offers precise steering and quick turn-in, making it a great choice for drivers who prioritize sharp handling.
• Good Wet Performance: Despite being a summer tire, the Proxes R1R performs admirably in wet conditions, with enough groove depth and water-channeling ability to reduce hydroplaning risks.
• Street and Track Versatility: The tire offers a good balance between daily street driving comfort and performance for weekend track days or autocross events.

Cons of the Toyo Proxes R1R

• Limited Tread Life: Due to the softer compound that provides high levels of grip, the Proxes R1R wears more quickly than tires with harder compounds. This is typical for high-performance tires.
• Not Suitable for Cold Weather: As a summer tire, the Proxes R1R is not designed to perform well in cold temperatures or snow. Below about 45°F (7°C), the rubber can harden, reducing grip.
• Higher Noise Levels: Performance tires with aggressive tread patterns, like the R1R, can be noisier than regular all-season tires, especially on highways or at higher speeds.

Common Applications

• Performance Street Cars: Ideal for high-performance vehicles such as the Honda Civic Type R, Subaru WRX/STI, Mazda MX-5 Miata, Nissan 350Z/370Z, BMW M-series, and similar sporty cars.
• Autocross: Frequently used in autocross events due to its excellent dry grip and responsive handling.
• Track Days: Suitable for light track use, offering a good balance between street tire durability and track-ready performance.

Sizes and Fitments

The Toyo Proxes R1R is available in a range of sizes to fit various sports cars, performance sedans, and coupes. Common sizes range from 15-inch to 19-inch wheel diameters, with a variety of widths to accommodate different setups and fitment needs.
