FWIW, the tread patterns on the Goodride and Ironman look good for those 5 tires on your link.....If you don't travel north in the winter.
Don't even think about trailer tires. I don't know you, but I expect your life is worth more than that.
That said, spring for the Defenders, You may spend $100, but at the end of the day you have a
Tire Rack top rated tire that is built to go 90K miles........Duh.
Looks like
Sams Club has got em for $85...dunno if that includes install, but even the $50 tire is going to be $65 delivered so you'll be out $80 for the set and you'll have to get them installed no matter what.
Defenders...nuf said.
