Selecting the Right Tire valves

Selecting the Right Tire valves

When tubeless tires first entered the tire market years ago, technicians assumed that if the tubeless valve stem fit the hole in the wheel it was the right tire valve stem. Today, that assumption could lead to severe problems.

Watch Size and Conditions

In some cases, the stem hole in the wheels for these tires is the same size as the valve stem hole in a passenger wheel. The TR413 and TR415 series valve stems were originally designed to handle inflation pressures up to 60 psi (4.1 bars). Today, they are rated at a maximum of 65 psi (4.5 bars). Be aware that many old catalogs the TR413 and TR415 series valve stems still at 60 psi maximum.

 

One of the most likely problems you may encounter with the TR413 and TR415 series valve stems at any inflation pressure above 65 psi is the vale stem running at a higher than normal temperature as a result of hot weather or other similar condition. This can cause the valve stem to crack, blow out of the rim hole, or become unseated.

All snap-in valve stems should be lubricated with a non-petroleum-based lubricant before being installed in the stem hole. The stem hole should be carefully inspected to ensure no sharp edges or metal slivers are present that could damage the stem。
