Here is the data; does anyone here know how to perform the calculation?

Old tires are P205/65R15 92V with a load rating of 1400 pounds at 44 psi.

New tires are 205/65VR15 94V (no "P" in front) with a load rating of 1477
pounds at 44 psi.

My car (1998 Honda Accord 4 door EX V6) has a GVWR of 4,235 pounds.

The manufacturer recommends 30 psi front and rear tire inflation pressure
with the original (old) tires.

Question:  What should be the adjustment (up or down, and by how many psi)
to take into account the 94V of the new tires instead of the 92V of the old
tires, or, stated another way, to take into account the new load rating of
1477 vs. the old load rating of 1400?  Should I now expect to inflate my
tires to 31 or 32 or 29 or what instead of 30?

(It could be the actual load rating of the tires should be equal but because
the new tires don't follow the "P-metric" standard there is a different
table used to express load rating?)

The old tires are Michelin MXV4+ and the new ones are Michelin Primacy MXV4.
Despite the similarity in names, these are different in construction.  The
Primacys have a much longer tread wear rating and the manufacturer recites
other differences.  The Primacy is the closest tire offered by Michelin for
my make, model and year of car; the original tire model is discontinued in
my size.

Thank you.
