| I noticed uneven wear on my tires. so, i stopped at a garage and i was told the tires were under inflated even though i had the tires at the recommending psi. i put the psi in that the technician recommended and the problem seemed to go away. i went in to have a routine oil change done at a local shop a year after this, and i needed to replace all 4 tires. they had worn down on the inside tread to the steel within only 26k miles. the vehicle has been driven conservatively, and mostly highway miles by my wife. so i put four new tires and had an alignment. *tr | |||
