The Triumph Street Triple S uses 120/70-17 front and 180/55-17 rear tubeless tyres. Both sizes fit 17-inch cast aluminium alloy rims. These are sport-oriented sizes designed for the bike's naked roadster performance and handling characteristics across city and highway riding.
For solo riding, maintain 36 PSI in the front tyre and 42 PSI in the rear. Check pressure when tyres are cold, before riding. Correct pressure ensures optimal grip, stability, and even tread wear. Adjust pressure if carrying a pillion or luggage for extended rides.
The Triumph Street Triple S uses tubeless tyres on both wheels. The 2020 model came factory-fitted with Pirelli Diablo Rosso III tubeless tyres. Tubeless tyres run cooler, maintain pressure longer, and are safer in puncture scenarios as they deflate gradually rather than suddenly losing air.
120 is the tyre width in millimetres, 70 is the aspect ratio (sidewall height as percentage of width), and 17 is the rim diameter in inches. This front tyre size balances responsive steering with stability. The rear 180/55-17 provides a wider contact patch for traction under acceleration and braking.
Yes, the Street Triple S tyre sizes (120/70-17 front, 180/55-17 rear) are available in radial construction from multiple manufacturers. Radial tyres offer better heat dissipation, longer lifespan, and improved grip consistency - ideal for the bike's performance-oriented riding style and cornering demands.
Replace tyres when tread depth reaches legal minimum or after significant wear. Service intervals are every 10,000 km or 6,000 miles. Inspect tyres regularly for cuts, bulges, or uneven wear. High-performance riding, frequent cornering, and road conditions accelerate wear compared to gentle commuting.
Triumph Street Triple S tyres typically range from Rs. 11,000 to Rs. 15,000 per tyre, depending on brand, compound, and performance level. Performance-focused sport tyres sit at the higher end. Prices vary by retailer, location, and fitment service charges. Compare specifications alongside pricing when selecting replacement tyres.
Yes, the front uses 120/70-17, and the rear uses 180/55-17. The wider rear tyre provides a greater contact patch for power delivery and traction. The narrower front tyre allows sharper steering response. Never swap front and rear tyres or use mismatched sizes - doing so compromises handling and safety.
The 2020 Street Triple S came factory-fitted with Pirelli Diablo Rosso III tyres. Other brands offering 120/70-17 and 180/55-17 sport tyres include Michelin, Metzeler, Bridgestone, and Dunlop. Choose tyres rated for the bike's performance and your riding style. Ensure load and speed ratings match or exceed OEM specifications.
Check tread depth regularly using a depth gauge - replace when below legal minimum. Look for visible wear indicators (tread bars) across the tyre surface. Replace immediately if you notice cuts, bulges, cracks in sidewalls, or uneven wear patterns. Age also matters - replace tyres over five years old regardless of tread depth.
