Hello! Your tires are load range "D". The same size is available in load range "E" also, which offers more tire safety and weight reserve, BUT the tire pressure cannot exceed the rim rating, which is for load range "D".
Your maximum tire pressure is
65 PSI
If you are considering a different size, this
tire size comparator will accurately display any difference in measurements and resulting changes.
