New Defender MS2 (285/50/20) installed about two weeks ago. Replaced Latitude Touring. Shop aired at 40ish - I set to 33 psi. Seem to be, for long highway runs, averaging around 2 mpg less than the Latitude (which was delivering around 20 mpg).
But very smooth - not sure if quieter or around the same noise level - I do hear some bearing noise (I'm close to 200k miles) so assuming if I just change those out it will get even quieter.
Visually Defenders do look more "substantial" than the Lattitude.
Great experience at Mavis Tire
