OK, so that tire can take it.

You're running OEM rims correct? Need to determine if the rims can take that pressure as well. In this case, I'd follow the ratings on the sticker on the door jam of the VX.

The last thing I'd suggest is to chalk a line across the tread of the tire, move the VX only enough to have the chalk line touch the pavement a couple of times, then check to see if the chalk is rubbed off evenly across the entire width of the tread.

Of course, keep an eye on wear over time as well. If the center of the tread is wearing too fast, lower the pressure. If the outside edges of the tread is wearing faster, increase the pressure. If there is cupping or uneven wear, get your alignment checked (actually cupping is usually caused by worn shocks rather than alignment).
