Not the same chart so see which says about 75 front and 80 to 85 rear.
On my coach the Michelin recommendation is too low and cause too much side wall flex. Based on weight they say 75 which is down from 110. I set mine at 100 and it rides well. My tires are 285 XXE and not 255 XRV.
If I remember correctly the recommendation for our 2015 Challenger 37ND was 90 front and rear. Not positive on that.
