Toyo Proxes ST 3 275/45R20 110 V Review

The Toyo Proxes ST3 in size 275/45R20 110V is a high-performance all-season tire specifically engineered for SUV-type vehicles. This particular specification features a 275mm section width, a 45% aspect ratio (representing the sidewall height relative to its width), and is designed for 20-inch wheels.

It boasts a robust load index of 110, meaning each tire can comfortably support up to 1060 kg (2337 lbs). The ‘V’ speed rating indicates it’s safely rated for speeds up to 240 km/h (149 mph). Generally positioned as an entry-level, budget-conscious option, this tire offers a blend of performance and value in its class.

It’s important to note that this tire does not feature a dedicated rim protection (or rim guard) element. A rim guard is a reinforced rubber area on the tire’s sidewall designed to help shield your wheel rims from minor curb damage.

This tire is constructed with reinforced (XL) rubber for a higher load capacity, meaning it’s built with additional plies or stronger materials to handle heavier loads than standard-load tires. Always consult your vehicle’s owner’s manual or door jamb sticker to confirm if reinforced (XL) tires are required for your specific vehicle.

Additionally, this tire does not offer run-flat capabilities. Each tire weighs approximately 15.91 kg (35.08 lbs).

Dry Performance

While the EU tire label doesn’t provide specific ratings for dry handling or braking performance, the Proxes ST3 is designed as a versatile all-season tire. For detailed insights into its dry road behavior, independent reviews and real-world driving experiences are often more indicative than the EU label alone.

Wet Handling

According to its EU tire label, the Proxes ST3 in this size receives a ‘D’ rating for wet grip. However, its tread design is engineered to provide efficient water drainage, which helps mitigate the risk of hydroplaning and contributes to confidence in wet conditions.

Fuel Efficiency & Noise

In terms of fuel efficiency, this tire receives a ‘D’ rating on the EU label. For rolling noise, it scores a ‘B’ with a sound level of 73 dB. This suggests a moderate noise level that should be neither excessively quiet nor overly disruptive during your commute.

Pros & Cons

• Pros:
  • Specifically designed for SUV applications.
  • High load capacity (Load Index 110).
  • Reinforced (XL) construction suitable for heavier vehicles.
  • Tread pattern engineered for efficient water drainage, reducing hydroplaning risk.
  • Moderate rolling noise level (73 dB, EU Class B).
  • Generally positioned as a budget-friendly option.
• Cons:
  • Lacks dedicated rim protection.
  • Does not offer run-flat functionality.
  • Lower EU ratings for fuel efficiency (Class D) and wet grip (Class D).
  • EU label does not provide data on dry handling or treadwear characteristics.

The EU tire label offers valuable guidance on key performance indicators like fuel efficiency and wet grip. However, it’s crucial to remember that it doesn’t encompass all aspects of tire performance. Other equally significant criteria, such as dry road handling, overall hydroplaning resistance, and treadwear characteristics under various driving maneuvers, are not included on the label.
