i have friends that run nothing but truck tires on there trailers because they've had lots of blowouts with regular trailer tires.trailer tires seem to dryrot very fast. every dual axle trailer i've ever owned seemed to always cut the crap out of one tire. i don't pull really long distances with my trailers but i pull them often. i buy trailer tires from a tire place near me. sometimes they get used trailer tire that look like new. i've ran a bunch of them.
