Bought these for my 5th wheel save the money. They just run out and don't last. New rims fitted with new tires, also installed TPM system, thank goodness two tires started to lose pressure after 50 miles. Next morning refilled the compressor to 15psi. I took the time to remove each tire and then went to the tire shop to replace all the tires, just threw them away, didn't even want to deal with returns.
