There are some differences in the driving requirements between the tires on your trailer and those on the automobile or truck you use to tow it. That being said there are distinct differences between the way trailer tires and tow vehicle tires are designed.

Your tow truck is a leader, which means traction is the main focus in the design of its tires. Traction allows your tow vehicle to take off down the road, make turns and brake to stop. Something else to take into consideration is tow vehicle tires are designed for ride comfort, which happens by the process of the sidewalls being able to flex.

Your trailer is a follower, which often makes the tire sidewall flexing a bad thing. Sidewall flexing on trailers, especially those with a high center of gravity like enclosed travel trailers or that trailers that carry heavy loads, is a primary cause of trailer sway. Typical passenger radial tires with flexible sidewalls can make trailer sway more prominent and cause problems. The stiffer sidewalls and higher operating pressures common with Special Trailer (ST) designated tires help reduce trailer sway.

Also something to consider is that Special Trailer (ST), as well as Light Truck (LT) tires are fully rated for trailer applications. This means ST- and LT-sized tires can carry the full weight rating branded on the sidewalls when used on a trailer.

However when P-metric or Euro-metric tires are being used on a trailer, the load capacity branded on the sidewalls must be reduced by 9%. This means P-metric or Euro-metric tires with a maximum branded load rating of 1,874 lbs. for use on a car is only rated to carry 1,705 lbs. when used on a trailer.

**Improperly inflated or over loaded tires will lead to tire failure. Make sure to check your tire pressure frequently.
**Don’t run different pressures on the opposite ends of an Axle. Unequal pressures will cause the axle to skew slightly sideways

**Special Trailer (ST) tires are constructed with heavier duty materials, so they are tougher than your average passenger vehicle tires

Special Trailer (ST) Tire Speed Ratings

Industry standards dictate tires with the ST designation are speed rated to 65 MPH (104 km/h) under normal inflation and load conditions.

However industry standards also stipulate, if tires with the ST designation are used at speeds between 66 and 75 mph (106 and 121 km/h), it is necessary to increase their cold inflation pressure by 10 psi (69 kPa) above the recommended pressure for the rated maximum load.

Do not exceed the wheel’s maximum rated pressure. If the maximum pressure for the wheel prohibits the increase of air pressure, then maximum speed must be restricted to 65 mph (104 km/h).

The cold inflation pressure must not exceed 10 psi (69 kPa) beyond the inflation specified for the maximum load of the tire.

Increasing the inflation pressure by 10 psi (69 kPa) does not provide any additional load carrying capacity.
