My personal thinking is regular sized tires can be used to make structure sized for regular (i.e. LMB) predators, and aren't "tight" enough (without creative additions such as plastic mesh, which wouldn't really be very hard to do) to be optimum for forage fish. IMO monster tires are bigger than needed.

Realize I am looking at the world through conventional tire-sized eyeballs - when I finally do tires, it'll be with the 160 or so 13" to 16" tires I have on hand for another purpose (their retirement from that use is looming).

BUT - if they're all free - it's your labor. Invest as much as you can/care to, in whatever size mix you like. I do like the way ahvatsa (I keep thinking he's Hawaiian :rolleyes: ) stuck his big tires in.

Look at the links ewest gave and get many more opinions than just mine.
