Sorry, I meant to type 50,000. It's this one, and I did not have to lube it myself. I put it in around 10,000 miles.
The computer does not list the specific psi, so that is probably something I should check - would that really cause that big a loss in fuel economy? I would think that by the time it got to single digit psi I would have noticed them looking flatter, but now I'm second guessing myself?
We just moved, and I had a lot of weight in the car before the fuel economy dropped, but I was still getting ~32mpg on average on the highway with the car fully loaded on the drive from Santa Fe to East Texas. This problem started soon after we unloaded the car.
The break-in period for the car is long gone, but I drove it as required for that period of time - it was majority highway driving (60 mile daily commute round trip on rural mountain roads, plus a couple of drives to Texas and one to Montana in the first 6 months of ownership). I don't think that there have been any other special conditions.
