Yea, I can't remember the last time I actually wore out a 16" trailer tire. FWIW, 15" are worse.

If I can ever afford another trailer, it will be a 3 axle 6,000+ lbs ea. If one blows, the 2 remaining should do a good job of supporting that side instead of one bearing all the weight and probably getting damaged. It will also give me time find a safe place to pull over to change the flat.
