How to Measure Your Valve Stem
1. Understand What You’re Measuring
The goal is to measure the depth of the valve stem well—the distance from the wheel’s mounting surface down to the bottom of the valve stem opening where the valve seat sits
2. Gather the Right Tools
-
A straight tool (such as a long rule, drill bit, or straight screwdriver)
-
A digital caliper or precision ruler for accurate measurement (ideally to 0.1 mm or 0.01″)
3. Measure the Depth
-
Remove the valve stem cap off your current valve stem
-
Insert your straight tool into the valve well until it rests flat on the wheel’s mounting surface. You want this to be on the shallow surface of the valve stem hole.
-
Mark or note where your tool aligns with the valve seat (or where it ends).
-
Withdraw the tool and measure the distance from the tip to the marked point—this is the well depth.
4. Determine Standard vs. XL RPV
-
Standard RPV is suitable for most wheels with a 15mm Valve Stem Depth or shallower
-
XL RPV is required for wells deeper than 15m (i.e 25mm)
5. Double‑Check and Compare
Cross-reference your measured depth with Apex’s sizing chart (e.g. for Method Race Wheels) or the specific guidance for your wheel brand below.

At Apex Designs Australia, we strive to make sure that you are getting the right product, the first time. Now you can check out the list of wheel brands below and find the recommended Valve Stems for you.
SAME WHEEL, DIFFERENT VALVE STEM
Whilst our guide below identifies which wheel works with which valve stem, it is important to note the offset in your wheel as this will also depict which valve stem you need.
For example, we have the King Offroad Hurricane 2, which, depending on the Offset, requires a Standard or XL Rapid Precision Valve.
Drag the slider from Left to Right to see the differences.
Always double check your actual wheel
Here is a video showing that the Offset can also play a factor in your valve stem depth. We are working hard to incorporate the Offset of the wheel into our reference tables, so if you want to let us know exactly what wheel you have, then we can update our website to help everyone else!
