I acquired a 17 foot 1987 Bayliner with what seems to be a light-weight Escort trailer with boards and 6.90-9 tires. I have blown two tires already, so I'm thinking this trailer is not meant for this boat. Does anyone know what size/kind of trailer is recommended? I'm not sure what the weight of the boat and/or trailer is. I live in ND and go to the lakes at MN (if there are any load requirements). Thank you.
