The Castle Rock ST205 is sold here as a single trailer tire. 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
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.
What tire pressure should I run?
Run the maximum cold pressure moulded on the sidewall when the trailer is loaded — trailer tires carry their rated load at full inflation, unlike passenger tires. Check pressure cold, before towing, and recheck before every trip. Underinflation is the most common cause of trailer tire failure.
Does this come mounted on a wheel?
Unless the product title says otherwise, you are buying the tire only, not a wheel. Any tire shop can mount and balance it on your existing rim. If the title mentions a set, the quantity named there is how many tires arrive, all in one size.
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.
