It might say 125 on the tire sidewall, but that refers to the pressure it might blow off the rim. In other words, the maximum allowable pressure. Not the recommended riding pressure.
If you weigh 350 lbs, including your bike/gear/clothes, Silca's respected calculator says to ride 98 front/100 rear psi. They don't offer calculations over 350 lbs
I ride 85/89 on my Conti 25's w/latex tubes. I weigh 145. Bike 18. Plus 12 for gear/clothes/shoes

Thanks for your reply. In the case of Vittoria, on their website, they specifically recommend staying within the range printed on the side of the tire. And of course, a range of 100 - 130 by its nature, isn’t a “maximum allowable pressure”. I’m 6’ 3” / 200 lbs and chose to stay toward the higher end of recommended range. I’m sure I could have gone much lower, but chose to stay with the range recommended by both Vittoria and my lbs.
Btw, the tires were great. Over 4,000 miles with one flat on a debris laden road after a strong storm.
