Racer X

My trailer, an 2006 came with Goodyear Marathons. To date,I am on replacement # 6 with only 12,000 miles on the trailer all due to separation. My bad, one had a bubble on the sidewall. Pressures were good, loads within range and speed under 70 mph. After learning about manufacture dates, the 5 on the trailer are all at least 6 years old when purchased. They should be recalled!
