My OEM tires gave me excellent performance for 9K miles and over four years. I replaced them at 5 years old. Don't believe everything you read on the Internet. I almost replaced mine when the trailer was new after reading all the horror stories, but thought if they are really so bad how do they get trailers from IN to CA? After a while you will see that the OEM tire naysayers are the same people year after year. Be careful not to curb your tire and keep max sidewall PSI (check first thing in the morning) and you may save yourself some money.
