The OEM tyre size is 90/90-19 for the front and 120/80-18 for the rear. Both sizes are confirmed in the official Royal Enfield specification sheet and apply to the standard Thunderbird 350 and the Thunderbird 350X variant.
Tubeless tyres fit the Thunderbird 350X variant with 9-spoke alloy wheels or aftermarket alloy wheel upgrades. The standard Thunderbird 350 with spoke wheels requires tube-type tyres, as spoke rims cannot maintain the airtight seal needed for tubeless fitment.
Maintain 22 PSI in the front tyre and 32 PSI in the rear for solo riding. These values ensure proper handling balance for the cruiser's weight distribution and long-wheelbase geometry across Indian highway and city conditions.
Royal Enfield Thunderbird 350 tyres range from Rs. 2,300 to Rs. 2,800 depending on tyre type (tube-type or tubeless), brand, and compound. Eurogrip offers both configurations at manufacturer-direct pricing with nationwide delivery across India.
The standard Thunderbird 350 uses tube-type tyres on spoke wheels. The Thunderbird 350X featured alloy wheels and tubeless tyres. Both variants share the same tyre sizes - 90/90-19 front and 120/80-18 rear - but require different tyre types matched to rim construction.
Replace tyres every 25,000 to 50,000 km depending on riding conditions, road surfaces, and maintenance. Alternatively, replace every five years regardless of km covered, or sooner if tread depth falls below safe limits or visible damage appears.
Upsizing alters speedometer accuracy, ground clearance, and handling geometry. The OEM sizes - 90/90-19 front and 120/80-18 rear - are engineered for the Thunderbird 350's cruiser geometry and weight. Consult a tyre specialist before changing from factory specifications.
Eurogrip offers tyres in 90/90-19 and 120/80-18 sizes, available in both tube-type and tubeless configurations. Match your tyre type to your wheel type - tube-type for spoke wheels, tubeless for alloy wheels - and verify load index and speed rating compatibility.
The 52P marking indicates a load index of 52 (200 kg maximum load per tyre) and a speed rating of P (150 km/h maximum sustained speed). These ratings match the Thunderbird 350's front-end weight and cruising capability for safe highway touring.
Tube-type tyres are the factory specification for spoke-wheel Thunderbird 350 models and proven for long-distance reliability. Tubeless tyres offer gradual deflation on puncture and lower maintenance, but require alloy wheels. Choose based on your wheel type - not preference alone.
