285/45 R22. Air pressure set by dealer at 35 PSI and rotated with every oil change.
That's strange Mark. My own experience with the LTX decades ago was that they easily went 60K miles and read from folks here and on other forums that sometimes even see 90K or more.
Is that the original wheel/tire combination for your truck? If so, what does the door sticker say for air pressure? I'm thinking they should be 32 but don't remember.
