My dads company has a Gooseneck trailer. I believe its an eco line or something like that. Its pulled by a F350. And for some reason its burning up the tires. Its a dual axel (4 tires) and in just this past year they went throught 10 tires. Since they had the trailer they had 5 blowouts. Its ran about 2-3 times a week the most they have ever hauled was 8,000 pounds while its rated for 12,000. Any ideas of what could be causing this.
