Utility Trailer Tires

Utility trailer tires carry the load whether you’re hauling fencing supplies to the back pasture, taking a mower across town or bringing feed home from the store. Finding the right trailer replacement tires starts with the tire size, load range and specifications recommended by your trailer manufacturer. Check the trailer’s information label and the markings on the existing tire sidewall, keeping in mind that an older tire may not be the correct fit. Special trailer tires carry an ST designation, but always confirm the approved tire type for your trailer before making a change. Tire load capacity needs to support the trailer and its cargo without exceeding axle, wheel or trailer weight limits. A higher tire load rating does not increase how much your trailer can safely haul. If you’re comparing radial trailer tires and bias-ply trailer tires, consider your hauling conditions and the manufacturer’s recommendations. Radial construction generally manages heat well during highway travel, while bias-ply construction typically has stiffer sidewalls that may suit certain hauling applications. Keeping utility trailer tires ready for the next trip takes more than checking the tread. Before loading up lumber, equipment or farm supplies, inspect each tire for cracks, bulges, cuts, uneven wear and anything lodged in the tread. Check tire pressure while the tires are cold, following the trailer and tire manufacturers’ guidance and staying within tire and wheel pressure limits. Low tire pressure, overloading and travel above a tire’s speed rating can contribute to excess heat and tire failure, especially on longer hauls. Spread cargo evenly, secure the load and follow your trailer manufacturer’s guidance for tongue weight. Check the spare trailer tire, too, so it has the proper size, load rating and inflation pressure before you need it along the roadside. For trailers that sit between jobs or seasons, follow manufacturer recommendations for storage and tire replacement based on age and condition, even if plenty of tread remains. A little attention before each haul can help you catch trouble before you leave the driveway.
