The Castle Rock ST205 is a trailer tire sold here as a set of 2. Castle Rock's ST line is trailer-service tires built for towed loads, not for drive or steer positions on a vehicle. Each size carries the ply rating shown in its specifications, so match the size moulded on your current sidewall before ordering. The line sells as a single tire, a pair for one axle, or a full set for tandem setups. Every order ships free from our Orlando warehouse.

FAQ
Can I run these on my truck or car?
No. These are special trailer tires, marked ST on the sidewall. They are built for towed axles only and are not designed for the steering and braking loads a passenger vehicle or truck puts on a tire. Keep them on the trailer.
How do I know which size to order?
Check the size moulded on your current tire's sidewall and match it to the size listed in the specifications above. If the old tire is missing or unreadable, your trailer's data plate or owner's manual lists the original fitment. When in doubt, contact us before you order.
Should I replace one tire or the whole axle?
If one tire failed early from damage, a single replacement in the same size is fine. If the rest of the set is worn or weather-checked, replace by the axle so both sides carry the load evenly. We sell singles, pairs, and full sets for that reason.
Check the full size marking on your current sidewall before ordering — our size guide explains every character. Ships free from our Orlando, FL warehouse. Questions? Call (407) 821-7008.
