I've got the LR on my J&S jack/stand and about to tackle removing the wheels, so I can get new tires installed. Front should be no problem, but I'm hesitant about dealing with the rear. Can one weak senior-citizen remove it? " hold wheel and remove axle" bothers me. I can't find the weight of the wheel/tire combination. I'm a one-man show here so I need some advice about this. How high should the stand be? Stand has 3 heights where it locks at the selected height. Advice appreciated, thanks.
