I should be getting my winter set (wheels+tires) today, and my jackpoint jack stands later this week, which means I should be ready for the swap at the end of the week. The jack stands come in pairs, which begs the question: when doing the wheel swap job, what's safest, using one or two jack stands? And if using two, what are the safest configurations? Intuitively I'd have thought that either 2 on the left or 2 on the right might be safe because in either configuration, one of the rear tires is always on the ground with the parking brake applied to it, which is an extra safety on top of the wheel chocks, but I'm wondering what the community wisdom is around this. Cheers!
