Front skinnies

PSI of your tire is mostly determined by the weight of the car, front and rear.

To figure out what is needed up front, the weight of the front of the car is divided by two. This gives you the load per side of the front of the car.

There is a rating on the tire that gives you PSI per pound of car.

Example 1600lbs at 50 psi meas that the tire can handle that max load at that max PSI.

dividing 1600 by 50 = 32 lbs of weight per PSI of inflation. This is your factor.

If your front end weighs 2000lbs then you divide that in 2.
1000lbs per side divided by 32 lbs/psi = 31.5psi/front tire.
