The inflation on the sidewall is the correct cold inflation pressure and the tires are sized and speced for the vehicle.
You are ASSuming that the tires were spec'd to run at their max. load and max. pressure and that might NOT be the case.
If they were over-spec'd, it might be better overall to run them at slightly less than the number on the sidewall. Over-inflated tires are not likely to suddenly fail but, depending on the specific tire, they might have slightly less traction and will make for a rougher ride and more strain on the suspension.
If the tire type has been changed.....for instance, the originals had a max. pressure of 80 and the new ones have 100.....it is NOT a good idea to run them at 100. Hit a big pothole and break your shock mounts......or worse.
