Got some new tires put on my boat trailer this weekend, and the ones they took off were from 2011. Tread still looked good on them, as it's obvious I don't take the boat out as much once my kids were born starting in 2013.
I think my old tires would have been fine tread wise, but figured new ones might make feel a little bit better.
Anyone else have tires on their trailer for 10-15+ years?
