Not sure of my boats weight, but know its very heavy. I learned a long time ago to not buy replacement trailer tires. I buy radial car tires to use on my boat trailer. This is only feasible if your trailer tires are 12" or bigger. Think about the weight of a car/truck. In most cases a boat is no comparison. They last much longer, (40,000 miles plus). In most cases they are cheaper. They trailer better. Whats not to like about that? Just my two cents.
