High pressure valve stems
I had a set of LT tires (load range E) installed on my truck last summer. They are rated up to 80psi. I'm not sure if the shop upgraded the valve stems to high pressure ones - I'm thinking they just re-used the original ones.
I want to air up my tires to 55psi for towing and I'm not sure what the original valve stems can handle, or if I have high pressure rated ones after all.
