What kind of adjustments can be made to minimize outside edge tire wear on my 2001 Toyota Highlander V6 AWD?

Larry, It keeps there cost down, example: You the leaser pick up your new lease vehicle with cheap tire that leaser paid let say $40.00 each for tires. You return car after a year, probably in your contract it states you are responsible for some wear items and damage, over mileage limit,etc. The lease rep. comes out measures remaining tread depth of tires and they measure out at 3/32 of an inch. Which then they calculate to be 95% worn. They do not use the price of $40.00 per tire, they use the price probably closer to $120.00 per tire in there calculation and get away with it, because this is determined to be the average cost to replace a tire of the market at the time.
To sum it up you could have to pay $456.00 towards tires wear unless you replace the tires before returning it to the lease company along with other expenses they deem as part of contract fulfillment.
This is only an example and does not mean all leases are like this it is just a plausible answer to question.

check your universal joints on the driveshaft as they will cause a bad vibration while driving

check trans mounts

Firstly, make sure your tires are in good shape, no rounded edges or balding. Secondly, have your tires balanced and checked by a tire shop.

alot of things could be causing excessive tire wear i would imagine the dealership would of told you if there was front end problems so we can rule that out but two more important things are rotating tires every 3000 miles and checking and or making adjustment on alighnments atleast twice a year. the angle that would cause the worst tire wear and is almost always the angle that is out is toe. I would start with a alighnment and making sure your tires are rotated

outside edge will wear on passenger side --- power steering causes this ,but if both tyres are wearing then have it tracked with a good old fashioned type tracking bar ,these laser things are only as good as the operator ,if it shows up as parallel then you could have worn bushes on the track control arm,is this vehicle subject to a annual vehicle mechanical inspection like in europe or just an emmisions test american style

2000 toyota highlander just had oil changed and VSC lightis on.
