Anyone use non-trailer tires on their boat trailer??

Yes, most current Boatmate trailers with the 18” option uses a p metric automotive tire.

The critical thing is that the tire and size you pick has a high enough load rating for the total weight of your boat,trailer and gear.

For example, a dual axle Boatmate trailer for a Supra SA with 18’s runs a 255/55/18 tire.

The load rating is 109 XL or 2271# max load at 50psi. That is 9084# max load for trailer/boat/gear.

A 28” tire in a 16 is looking like a 235/65/16 and the highest load rating would be 1929# each, is that high enough for your boat/trailer/gear?

Edit: You can get 235/65/16 is a load rating of 3195# each.

Side note, Boatmate uses trailer king rst tires, they have a higher load rating BUT are made in China, so take that into consideration.
