Tried them on a 2021 Jeep Wrangler Rubicon (JL) with stock 33" tires (factory remanufactured rims I think) and a pair of brass steps on the end of the valve stem There may be a gasket in the cap or something that could compress if I take out my pliers to screw it in further, but I won't be carrying pliers around to gain access to the valve stem and I won't risk damaging it valve stem or product.
