What should the pressure be on my new tires?
According to the tire placard, at maximum load, the tire pressure should be 50 psi in the front and 60 psi in the back. When you locate that tire at those pressures on the load inflation chart, the rated loads are 2,205 lbs. and 2,469 lbs. The proposed new tires are 285/70R x 17D…
What should the pressure be on a SL tire?
The maximum allowed pressure listed on a tire’s sidewall can be higher however. Some tires list 44 psi and many higher speed tires will list 50-51 psi. This added pressure does nothing for load capacity. Pressures above 35-36 psi for SL tires and 41-42 psi for XL tires will not increase the load capacity of the tire.
When to use maximum air pressure or maximum tire pressure?
This is because the maximum air pressure is the right number when the truck is fully loaded. The sidewall should also tell you the load capacity at the maximum tire pressure. That capacity can likely support half your truck’s weight, or more. The advantage of using this maximum pressure is that it’s safe.
Who is the best guy to check tire pressures?
Howard is a DIY guy who usually sells a car in better condition than he bought it. He prefers older and foreign cars. To check tire pressures, you need a good tire gauge, and you need to know the appropriate tire pressures for your tire-wheel-car combination.
