Let me start with the idea that I know trailer tires are ideal. I'm curious if anyone runs or has experience running non-trailer tires on their boat trailers?

I have access to a set of rims that I really like to replace the steel ones that came on the trailer originally. The ones I have access to are 1" larger aluminum. 15" OEM to 16". The issue is that the fenders were obviously designed to accommodate the 15" rims & I only have 30" of clearance. So I need a tire that is 28" in total diameter to make that work. And I don't really want to replace the fenders. It doesn't appear as though a 16" tire of 28" or less exists in a trailer version. I'm assuming because they would be considered lower profile. I know I've seen a lot of newer boats with huge rims & lower profile tires. From what I'm seeing, I'm guessing that means they're using some sort of passenger tire rather than STs. Trying to decide if it's worth the risk or not.
