Am I doing something wrong, or should I expect to get less than 20,000 miles with each new set of tires that I buy for my 2005 ES330? The car came with Bridgestone Turanzas EL42, the tire size is P215/55R17. That first set lasted 17,000 miles before they became nearly completely bald. I replaced them with the same tires (Bridgestone Turanzas) and this time only got 11,000 before they went bald. The most recent set, I rotated the tires twice while I had them and also had the alignment done twice during that same time period.
Any suggestions on what tires to get next, what to do differently to get better mileage in the future and what mileage should I expect with my new set? Is poor mileage with these cars just a given, I would love to hear others' experiences with this matter.
