Looking for boat trailer tires. Had a blown out tire this weekend. Had no choice but to buy a Goodyear Marathon at Walmart to get home. Just purchased this used boat and trailer and after this blowout, I'm thinking I need to replace the tires and get a good spare. What are the best? Maxxis? From what I've read so far, trailer tires are all crap, or so it seems. Debating on getting a 2nd GY Marathon for the other side and using the current old tire as the spare. Or also considering using the GY Marathon as the spare and breaking down and getting 2 other newer tires. What do you guys think?
