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

 

[gregaust]

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

ya, its a bit low... maybe unstable at the top end.
I run 12-14.

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.

I run my 27x11.5 at 20 - 22 psi on my 4200 Galaxie

 

[fat64]

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

My car will blow the tires off with anything higher then 15psi

 

[dfree383]

Start at 12 and go up in 2# increments.

Same here - start at 12 and go up.

When do you stop adding air? I

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.
