How heavy is my chrysler 105hp boat?

[liusigou]

My boat is Chrysler 105hp outboard. The year is 1978. model is 1057B8H. Current the tire size is 185 80r13. I need buy a new pair of tires for the trailer. How can I know the current tire size can match the heavy of my boat. Thank you.

you cant unless you have it weighted

why not just replace with the same tire type and size?

That model number is for the motor I believe.
Make sure you get trailer tires.
As MH said, weigh it.

Should be around 490 pounds. I had a 120 hp Chrysler. But for tires you need to weigh your whole setup.

That world be the weight of the motor. The OP needs the weight of boat, motor and trailer.

Weigh it, or take it to a reputable tire center and have them do the replacement.
