Why boat trailer tires blow out with plenty of tread left

A boat trailer tire can have remaining tread and still need replacement. Its age, condition, inflation, load and service history all matter. Tread appearance alone cannot tell you why a tire failed or whether another tire is ready for the next trip.

Start with the trailer and tire specifications

Use the trailer manufacturer’s tire type, size, load and inflation guidance. The tire already fitted may not be the correct one. Do not substitute a passenger tire merely because it fits the rim, and do not assume a different tire increases the trailer’s rated capacity.

Check age and condition together

Read the tire’s date code and follow the vehicle and tire manufacturers’ inspection and replacement guidance. There is no single replacement age that establishes the condition of every trailer tire. Cracks, bulges, pressure loss, irregular wear and unknown history deserve attention even when tread remains.

Before towing

• Check cold inflation against the applicable manufacturer guidance, not a guessed setting.
• Look for damage and pressure loss, including at the spare.
• Confirm the loaded trailer remains within its ratings.
• Have a damaged or questionable tire assessed before the trip.
