Check with Firestone first, but usually the 44
psi max inflation pressure means that this tire
has a re-inforced sidewall (2-ply
construction/6-ply or C rated). Combine that with
the 97 load rating and it meets the spec for the
optional tire size shown in the door jamb of most
2WD Vanagons. The 774 rpm number is 4% lower than
the calibration number on most 2WD Vanagons (805)
so your speedometer reading will be off by the
same percentage.

Inflate all four tires to Max PSI and see if the
sway lessens. If it does, then the tires are
suspect. Or install 4 new Light Truck tires and
screw up the ride and handling even more.

Good luck,

Tim
