Different vehicles
As smaller single-rear-wheel van campers become more popular, please be aware that installing new tires in front is not necessarily the best choice (if only replacing two at a time).
With larger motorhomes that have dual-rear-wheels, one can make a good argument for having best tires in front because a rear blow-out has a built-in backup; whereas the fronts don’t.
However, when vehicles only have four wheels (SRW) like most vans do, a rear blowout can be much more dangerous than a front blowout. For that reason I would install my best tires on rear axle when equipped with single tires.
Personally, I rotate tires often enough that I usually end up replacing all four at same time.
