Just notice my nox had H rated tires on it. Anyone know what the vehicle top speed is?

Not really the type of vehicle where a high top speed really matters, but I'm gonna guess somehwere in the neighborhood of 115-120 for the 4cyl and a little higher for the V6. Of course I don't know if there is a speed limiter involved, but if there is then the top speed is likely the same for both engines.

H rated tires are good for 130 mph. If the vehicle can exceed that speed the computer will limit it to 130 or slightly less.
I don't know what the top speed is on a V6 but probabably around that 130 mark.

Car and Driver noted the top speed on the 4 cylinder:

Top speed (governor limited): 112 mph

The 4 cylinders have T rated tires good for 118 mph so the 112 makes sense.
