Hi, I would say, if all four tires are the same size [physically] and similar in tread design, use them for now. But I don't believe in mixed tires on any vehicle. Many tires with the same size markings on them, from different makers, are actually physically different in size. Could be, and if it were me, and I needed a tire to replace one that got damaged, then and only then, would I put a different brand tire on. That is, if the one I needed wasn't available. Different tires have different handeling and traction characteristics; Much more important on a car versus a trailer.
