Just took the X in to replace the tires because the inside wore down to the belts on the rears without me noticing. (stock Conti Silent Cross Contact LX Sport staggered). Not sure the milage I got on them but its in the 35k-40k range; about what I got with the first set. This will be set 3. What should my suspension settings be to increase the life of my tires? From what I have put together: Normal (with low at 75mph+) Results in longer tire life, less wear May result in acceleration shudder (though I have never experienced) Always Low Results in shorter tire life, more wear May eliminate acceleration shudder Anything I am forgetting or not considering. What do you think?
