Re: How long should trailer tires last
Sitting in the sun, underinflated, overloaded, are all tire issues that affect how long they last. Here's the deal: Buy new tires but before having them mounted, check the date code. Insist that they NOT be installed if the date code is not from the current year. From this point on the date code will determine when to replace them since there is a fair chance the tread will still look good when the rubber is cracked, hard as a bullet and therefore dangerous. Replace tires at 4 - 5 year intervals, or if protected and/or stored indoors, 6 years. Either way, pay attention to the sidewalls as this is a better indicator of condition than the tread. I just had two tires replaced under warranty that were on a 2008 trailer. The date code on the tires were 2004 and they were split wide open on the sidewall and in the tread grooves.
