This Journey (Wanda) P815 trailer wheel is designed for trailers requiring a durable and road-legal tire. Its key benefit is the stable, wide profile and hard-wearing construction for reliable towing. A potential caveat is its specific size and stud configuration, requiring compatibility checks before purchase. This wheel features an 18.5x8.50-8 tubeless, E-marked tire with a 6.5mm tread depth on a heavy-duty 4-stud, 4-inch PCD steel rim. It offers a max load of 940lbs (425kg) and a max speed of 81mph.
