CASTLE ROCK ST225/75R15-10PR Trailer Tire and 6 Lugs Silver Wheel Bundle
The Castle Rock ST225 is sold here as a single trailer item. These are Castle Rock trailer tire and wheel bundles: complete assemblies with the tire already mounted on a silver or galvanized wheel, ready to bolt onto your trailer's hub. They use special-trailer construction with the ply rating shown in each listing's specifications, which puts them in towing duty rather than passenger use. Buy a single to replace one damaged assembly, a pair for a single-axle trailer, or a full set of four for tandem setups. Every bundle ships free from our Orlando warehouse.

FAQ
What does the ply rating mean?
Ply rating describes the strength of the tire's casing — a higher rating generally means a stiffer tire that can carry more weight at its rated pressure. You will find this tire's ply rating in the specifications above and moulded on the sidewall next to the size.
Do these come already mounted on the wheel?
Yes. Each bundle is a complete assembly, so the tire comes mounted on the wheel. Before installing, check the inflation pressure against the figure moulded on the sidewall, then bolt the assembly onto your hub and torque the lug nuts to your trailer maker's recommendation.
How do I know this will fit my trailer?
Compare the size moulded on your current tire's sidewall with the size listed in the specifications above, and confirm the wheel's bolt pattern matches your hub. If either one is different, stop and contact us before ordering — we can point you to the listing that matches your trailer.
Assemblies arrive mounted and ready to bolt on. See assembly vs separate for how they compare. Ships free from our Orlando, FL warehouse. Questions? Call (407) 821-7008.
