I,ve done it both ways. I rented a uhaul to take a car from Mich to Fl ,even though I owned my own car trailer I didn,t want to drive back with an empty trailer and was travelling out west first. One tire shredded in Fl. A call to uhaul brought a new tire and roadside assistance.
I,ve also bought new a one and travelled with it across country and was able to sell it at home for more than I paid ,so either option works.
Only thing I,ve ever had fail is trailer tires ,even new ones are mostly garbage.
