Tire’s have several areas of specification.
You all are talking about load rating.
Old days. A 10ply tire meant actual 10 layers (Ply) of cotton fabric, but today’s material science has 1-2-3 or more able to do what took 10 plies to do in the old days. Back then, you had to look up the tire size in order to know what it is rated for. As 10 ply was out of context without the tire size.
There is (actually already has happened and the ply rating is just to help old references in line) move away from ply ratings and into the numeric ratings. This numeric rating is an absolute and does NOT matter which tire size it is molded onto. A much better system.
There are other attributes that matter in this discussion. The main one, IMHO, is the rim width in reference to the tire section width…or that tires spec sheet listing recommended wheel rim width.
Too narrow will have too much sidewall bend back and have the tire behave differently from on mounted on a wider rim width.
For the OP, bouncing means (IMHO), that the tire when compressed by road conditions…spring back faster than a softer tire. As tires are also part of the damping (shock absorber) system.
As recommended by others, suggest lowing your tire PSI but leave enough to carry the load you have on it. Another is to change to higher dampening rate shock absorbers.
There are many sites with ‘what a tire sidewall markings mean’ and here is just one of them:

Original image at the TireRack site has each a clicky jumping you to their detail info site. Each is specific to a table that all tire OEM’s must have. Speed rating, weight rating, heat rating, wear rate, etc, etc…
