Valve Stem Recommendation for Trailer Tire with Unknown Valve Stem Hole Diameter

Updated 03/29/2018 | Published 03/27/2018

Question:

How can you determine tire valve replacement diameter? I have a 2012 Eclipse Evolution X Series M-20FBS. Tires are st205/75r15 max psi 65. I’m looking to replace valves stems when I replace tires. I have attached a picture of the current valve stem on the rim.

Measure the diameter of the hole the the valve stem is coming through in the picture you submitted. With that you'll be able to find which valve stem you need. The two common sizes are .453 and .625 inch which the part # AM20906 is a confirmed fit for both so it would work for you. This can handle over 100 psi so it would work well for you in that regard as well.
