Re: tires
All good responses. If it were me, I would use them it is was a light load. I would compare the load ratings.
I do agree that you should use ST (Trailer) tires, but $35 a tire, not a bad price, your call....
I tow trailers all day everyday for my business. After you start replacing 2, 3 and 4 tires a year (ST tires) you start asking yourself it used truck tires would work just as well for just as long. I have 3 trailers right now with truck tires on them on one axle or another. One trailer, all four tires are truck tires... have not had a problem with them at all....
