I have been pulling trailers for my business for some years now. I have tried a couple brands of trailers but all have been 6x12 tandum axle cargo trailers. I have pulled these with everything from 1/2 ton v6 gassers to dualies. All trailers have done the same thing i get tons of flats, i have done my 4th flat tire in the last 4 weeks. it seems like the tires are either doing 2 things going flat fast or going flat slowly. this is such a PIA, I do a mix of driving some highway but much of it in town and around neighborhoods. Does anyone have an idea of what is causing me so many trailer tire flats and maybe I can come up with a plan to keep this from happening. Also i have yet to have a flat tire on the tow vehicle BTW
