1st. do a couple of small burnouts on a blacktop road and measure your tire marks width. You want to adjust your air pressure to get the effectiveness of the full width of the tire. Most narrow rims require 18-19 lbs of air pressue cold. The wider rims require more air pressure, even up to 24 psi. This is a little test we did with 7" wide and 10" wide rims and MT ET Streets.
Once you get the proper tire presssure, then you are ready to go racing.
Do a goood serious burnout till smoke is coming of your slicks, then ease off the brake allowing the truck to move forward till the tires bite.
Now you are ready for a launch.
Have fun.

My wheels are 10 inch wide what psi do you suggest
Hi morrisc.
I run 8in rims. I run 16 lbs. I launch[hard 2 hold sometime] at
1200 rpm. Being wider u might want 2 start at about 21 psi.,and
see how it goes. If they are 2 low u will know at about 90 mph,
can u say HOLD ON.
Later J.R.

first off, I'm new at this(drag racin' and ET streets/10" ARE wheels) but I tried runnin' them at 24psi-hot and the edges of the tread were still new--after 20 or 30 short burn-outs and 1/4 mile passes. Therefore, too much psi--this past two Fridays I dropped the psi to 15psi-hot and got full 'wear', edge-to-edge. I just think 21psi will be way to high?
