Description

Rotalla Setula S-RACE RU01+ (245/35R21 96Y XL)

The “High-Value” 21-Inch Specialist. Style and Performance on a Budget.

While the standard RU01 is a favorite for 18- and 19-inch wheels, the RU01+ is specifically reinforced for 20- and 21-inch applications. It aims to provide the stability and low-profile aesthetics required for modern executive saloons and electric vehicles while maintaining a surprisingly quiet cabin.

✨ Key Technical Features

• 🏎️ Asymmetric “5-Rib” Design:

  The RU01+ features an updated asymmetric pattern with five wide grooves (compared to the four found on smaller RU01 variants). This provides a larger contact patch and enhanced lateral stability, which is critical for maintaining steering precision in heavy, 21-inch equipped vehicles.

• 🔇 Optimized Block Noise Suppression:

  Despite its wide footprint, the RU01+ is engineered to be quiet. The tread block sequence is computer-optimized to disrupt air resonance, achieving a 71 dB noise rating. This makes it an excellent choice for Tesla Model S owners who want to maintain a hushed interior.

• 🌧️ Effective Hydroplaning Resistance:

  The five longitudinal grooves work to evacuate water rapidly. While it holds a Class C rating for wet grip, it is designed to be predictable and safe for daily urban driving during Singapore’s heavy afternoon thunderstorms.

• 🛡️ Reinforced XL Sidewall:

  The Extra Load (XL) construction is vital for 21-inch low-profile tyres. The RU01+ features a fortified casing that helps protect your expensive alloy rims from “curb rash” and pothole damage, while supporting the higher weight of modern performance sedans.

• 📏 Updated Silica Compound:

  The RU01+ uses a high-elastomer silica blend that improves wear resistance and reduces heat build-up. This helps the tyre stay “fresh” longer, addressing the common concern of budget tyres hardening prematurely in tropical heat.

📊 Performance Summary

• Dry Handling: ⭐⭐⭐⭐ (Solid and stable for daily use)

• Road Noise: ⭐⭐⭐⭐⭐ (Very quiet for a 21-inch UHP tyre)

• Wet Safety: ⭐⭐⭐ (Safe for normal driving; avoid track-limit rain use)

• Value Factor: ⭐⭐⭐⭐⭐ (Excellent price point for a 21-inch tyre)

The Rotalla Setula S-RACE RU01+ is the premier “smart value” choice for 2026. It is the best option for drivers who want the aggressive look of 21-inch wheels and a quiet, comfortable ride without the $500+ price tag per tyre of Tier-1 brands.
