Their 28x10.5 in a 4200 lb car. Does 10-11 lb sound a bit low?

My friend runs his on 13 lb same size as yours but checks between runs since pressure goes up when they get warm.

Run as much pressure as you can without losing traction.

I run 26x10.5", run 20-22psi and run 1.5x 60' times, 3660 lbs, 3.50 gear.

It's something you have to experiment with.

Yeah, I was thinking around the 20 lb mark to start with.

When you lose traction or consistancy.

Also, watch the pattern across the tire. It should have an even wave across the tire face.

trial & error. just remember that amt of air will affect reaction time. if you find 60' and et dont change from say 12-17 pounds, then you can use that to adjust your reaction times. but first find what the car likes, even if you get a little dance at the fast end. like the other guys said. the more the better until you lose traction or consistency.
