<p>The Supercargo SU03 18.5x8.50-8 tire and wheel assembly is a heavy-duty, ready-to-install replacement for lightweight boat, Jet-Ski, and utility trailers. Pre-mounted on a durable white steel wheel (4 lug on 4" PCD bolt pattern), this 6-ply Load Range C bias setup supports up to 940 lbs at 50 psi. Its extra-wide 8.4" low-profile design prevents sinking on sandy shores, while the aggressive block tread delivers maximum grip on slippery, wet boat ramps.</p>

  • COMPLETE TIRE & WHEEL ASSEMBLY - Comes factory-mounted and ready to install. Features a heavy-duty white steel wheel with a standard 4 lug on 4" PCD bolt circle pattern.
  • LIGHTWEIGHT TRAILER FITMENT - Perfect direct replacement for single-axle Jet-Ski, PWC, Jon boat, and lightweight fold-up utility trailers using standard 4-bolt hubs.
  • EXTRA-WIDE BEACH FLOTATION - The ultra-wide 8.4" footprint distributes trailer weight evenly. Prevents your light trailer from sinking or rutting into soft sand, mud, and gravel shorelines.
  • LOAD RANGE C (6 PLY) - Tough tubeless bias-ply construction carries up to 940 lbs at 50 psi. Rigid cross-ply sidewalls deliver excellent towing stability without swaying.
  • BOAT RAMP GRIP TREAD - Features the signature SU03 aggressive block pattern with an 8.2/32" depth. Ensures confident, non-slip traction on wet, slippery launch ramps.
  • DOT-APPROVED MARINE SAFETY - Fully compliant with federal standards. Engineered for legal, safe highway transport between your storage facility and the water.
