Tire Loads Inflations Part 2 Marble

Selecting the correct tire pressure on multi axle trailers.

Tire loads inflations part 2 marble.

A tire s maximum load table 2 is the most weight the tire is designed to carry. Roger marble spent 40 years in the tire industry working for a major. Since a tire s load carrying capacity is related to the tire s size and how much inflation pressure is actually used maximum loads are rated with the tire inflated to an industry assigned inflation pressure. Rolling resistance sometimes called rolling friction or rolling drag is the force resisting the motion when a body such as a ball tire or wheel rolls on a surface it is mainly caused by non elastic effects.

Here we find the details of valve stem designs as specified by tra. Valve stems and tpms part 2. I have always considered the cold psi on the side of my 22 5 rv tires to be the minimum to carry the maximum rated load. I need one clarification.

We at fifth wheel street no longer recommend adjusting trailer tire inflation pressure below the pressure associated with maximum load psi rating molded on the sidewall and only if the wheel rim is appropriately rated for tires that have a maximum of 85 psi or less regardless of the measured scaled weight of individual tire or axle. That is not all the energy needed for deformation or movement of the wheel roadbed etc is recovered when the pressure is removed. Two forms of this are hysteresis losses see. Thank you for all of your informed comments regarding proper tire care.
