Who Has Replaced Stock 19" Michelin Latitudes On Rx350?

[greyrx350]

Mine only have 5000 miles on them but I'm wondering if replacing them with a taller profile tire will help make it a smoother ride. Has anybody replaced these stock tires and noticed a difference with a less harsh ride?

Take 1 or 2 pounds PSI out of the tires; probably won't trigger the tire inflation warning.

A size change in tire will potentially toss out your speedo calibration, alter your transmission shift points, etc. etc. Three percent deviation is about as much variation as the computer can handle. As for the firm ride, enjoy the fact that the car handles much better than the previous generations.

Mine came with Bridgestone and I love the ride and handling. You would think that tires would change handling more than the ride.
