I bought my trailer in 2001 when I first got my boat. I used it for 1 year during the re built process every weekend bring the boat back and forth to work on it. In June 2002 was the first time the trailer went into the water when I finished her and started using her. I use my boat approx 40 times a year driving 20 miles one way to the dock. In June of 2008 I had my first tire problem the steel separating from one of my tires causing a blowout. I replaced that one tire and about 3 months another tire did the same thing so I replaced the three left with all new. If I were you I would keep what you got have a new spar ready to go and inspect them every trip for a while. I use Stanlass Steel lug nuts which in my opinion are worth the $1 something price tag each just incase I do have a problem I can get the wheel off easily. I also keep a complete hub assembly in the truck just incase.
