D = bias Tires R = radial Tires Most trailer Tires are either 6-ply or 8-ply. Other info: Radial "R" trailer Tires dry rot more quickly so if your trailer sits idle for weeks and/or months, it's best to get the bias "D" tire. In other words: If you travel a lot, get "R" and if you sit a lot, get "D". 175-80-13 ,175-80-13, 205-75-14, 205-75-14, 205-75-15, 205-75-15, 225-75-15, 225-75-15, 235-80-16
