Had a lot of trouble with Goodyear Marathons but tried their newer Endurance tires on my trailer. 10K miles and they still look great; no bulging sidewalls and with a higher load range than the Marathon I think it's a good economical tire. If you want better then you probably need to switch over to the 16" combinations. BTW, unless they are babied and keep out of sunlight most of their lives 5 year replacement is recommended.
