Do I need 3-ton or 6-ton jack stands?

Rated capacity is per pair on most consumer stands, and reviewers in r/Tools repeatedly note that going higher than needed isn't just about weight, it's about base size and saddle height. A 3-ton set is fine for sedans and most crossovers; trucks, full-size SUVs, and lifted vehicles benefit from 6-ton stands for the wider base and taller lift range, not because the vehicle weighs six tons.
