I know what I believe, but trying to convince my partner is another thing. She has a fairly new Honda SUV with about 16,000 miles on it.After only 10,000 miles she needed new tires. Just last week a local outfit told her she needed a new air filter. In my view she shouldn't be having to replace these things on a vehicle with so little mileage and I'd like to hear from anyone else who has had maybe a little more experience with such things.On the other hand, she probably is a little rough in turning the vehicle. I think many drivers turn in a way that the power steering tends to grind the tread away prematurely. I think this happens more if you didn't experience a time before power steering when you learned the importance of allowing the car to gain a little forward momentum before forcing it to turn. Just turning at a dead stop can be murder on tire treads. The powering mechanism will allow you to do it, and you may have to when parking in a tight space, but the more you're inclined to do this the more wear you'll develop.As for the air filter I was reading recently that on newer vehicles the computer employs sensors to adjust for how dirty the thing may be makining regular cleanings even less important. On old vehicles we used to just take the thing out and bang it a few times to get (some) of the dust and dirt out and we were good for a few more miles.Still it's hard to imagine a new vehicle could need a new one after only 16,000 miles if she's only driving over relatively clean city streets.Any thoughts?
