on the way back from IT SPEC-tacular and seeing various folks on the road side changing tires, i realized that my race jacks are not rated for the one side of my enclosed trailer when it is loaded.

i have a 1.5 ton aluminum race jack and probably ~9000 #'s in the trailer total.

is this why folks use the ramps like these:



i realize that would be more load on the axle but that is basically a static load compared to the dynamic load bouncing down the road.
