My selling dealer put it into my tires after I purchased the truck, and it was 29.95.
I did notice that the tire pressure stays constant for all the tires. I dont know if it is related to the nitro-fill or the better seal at the valve stem with toyota's TPMS system....hmmm
I do get great gas mileage, but who knows if it is directly related; as, it has been in the tires from day one, so I have no baseline for comparison.
