I hardly use it, sits on my driveway all year long. Maybe 2-4 per year. Had it for about 4-5 years now. All 4 tires are Contender tires from Discount Tire, perfect rated for these trailers. 2 of them were replaced last summer, and haven’t use them since then. Other 2 were replaced the year before. New batteries and has a solar on top of the box to keep them charge.
