Setting Air Pressure In your Tires
There are many different thoughts about how to set the air pressure for the best handling of a dirt track car. Once the car suspension has been set up, you can fine tune the handling of the car by varying the air pressure in all the tires. To be able to set the air pressure correctly, you will need a good quality air gauge that reads in small increments such as 1/2 pound. Visit AIR TOOLS for examples of tools for setting air pressures
As a general rule in most classes the rear tires can be set between 10 and 16 pounds. I usually have my street stock set at 10 in the left rear and 12 in the right rear. If the car is loose in the heat, I drop the right to 10 or 11. I run about 11 or 2 in the left front and 18 to 21 in the right front depending on how wet the track is.
If you are running a mini stock or bomber class with less horsepower, you may need to up the rear tire pressure so the car can break loose in the corners which enables you yo slide around faster then just steering around the corners.
If the car is tight or wants to”push” in the corner (it does not want to turn) you can increase the difference in the rear tire settings for example if you had 10 lb in left rear and 12 lb in right rear increase the right rear to 13 or 14 lb. If the car is loose (it wants to come around too much) you can decrease the difference in the rear tires for example if they were 10 lb in left rear and 12 lb in right rear change to 10 lb in left rear and 11 lb in right rear.
