Two friends of mine have recently had multiple trailer tire
failures (tread pealing off) while on trips. When purchasing replacement
tires, friend #2 was told that trailer tires delaminate in about 4 years.
The tire seller also mentioned that it was easy to determine when the
tires were near failure. He mentioned that the center section of the
tread raises up. So I go home and check out my 4 year old ST205/75-15's
and they are very distinctly raised in the center, approximately 1/4 inch.
When I checked the spare that is the same age as the tires on the
trailer- it looked normal. I am planning to buy 4 new tires come spring.
Reading anything I could find on the web about trailer tires I
found the it is highly recommended to replace them every
4 year. I also found info on tread delamination, I could not find any
thing mentioned about the tread raising up.
Has anyone out there had similar experience with raised tread?
