Royal Enfield Classic 350 Tyre Size

The J-platform Royal Enfield Classic 350 completely overhauled the vintage roadster's ride quality, shedding the brutal vibrations of the old UCE motor and pairing a rigid twin-downtube spine frame with a 100/90-19 front wheel and 120/80-18 rear wheel. The large 19-inch front hoop is vital to the Classic's steady, authoritative straight-line tracking, creating high gyroscopic stability that allows the heavy 195 kg machine to track effortlessly across broken gravel mountain passes in Spiti or Ladakh. Factory tyre construction depends on trim: Dark and Stealth series feature cast alloy wheels with tubeless tyres, whereas traditional Halcyon and Chrome editions use wire-spoked wheels with inner tubes. For cross-country overland touring, riders frequently swap stock highway-tread tyres for block-pattern dual-purpose rubber like CEAT Gripp XL or Ralco Speed Blaster to handle slush and loose riverbed stones. Royal Enfield specifies 32 psi at both front and rear for solo riding, but with a pillion and heavy metal panniers, increasing rear pressure to 36 psi is mandatory to avoid bottoming the rear twin gas shocks against the swingarm stops.
