What is the correct tire pressure for a Suzuki Samurai with 22560R15 tires?

Answer 1

The answer is, it depends.

I always look at the weight rating on the side of the tire, consider this calculation:

Weight rating of tire is 1200 pounds at 32 psi.

The Samurai is roughly 2400 pounds with people and gear.

That means there is 600 pounds on each tire (600 X 4 = 2400)

If each tire is rated at 1200 pounds at 32 psi then it will handle 600 pounds at 16 psi.

Therefore the minimum pressure is 16 PSI and probably half that for sand, say 8 psi.

Remember the softer the tire the softer the ride but the harder the steering and Vice Versa (the reverse) the harder the tire pressure the easier to steer but the bumps will put you in the hospital!

I like to get good mileage and somewhat easy steering but still soften the ride so I run 20 psi. Using the above calculation works well for me.

Please Note: This assumes the pressure and weight capacity are linear with each other, please contact the tire manufacturer for your tires specific relationship.
