Axle alignment causing uneven tire wear

Uneven tire wear on a trailer, especially wear concentrated on one edge, points to axle alignment more often than people expect on trailers with multiple axles. Trailer axles can shift out of alignment from hard hits, overloading, or just years of use, and it's not something most people think to check since cars get alignments but trailers rarely do. A mobile alignment check with the right equipment can confirm before you spend money on tires that'll just wear the same way again. Which tires are wearing unevenly, and on how many axles?
