Should there be an alignment problem with a 2008 Toyota Highlander with 17" Toyo tires @ 20,600 miles? Is this normal wear and tear, or is it a manfacturer defect?

Your tire wear is something out of whack, bad wheel bearing, ball joint, strut, alignment, lots of stuff, a mechanic should be able to tell you what it is.
Check out tirerack.com for tire and wheel packages that would give you a lot of different options and combos on different sizes. I had a car with 16" summer wheels and 17" winter wheels.
Not sure about your vsc light, maybe bad senson in the bad bearing, but then seem like abs light would be on as well. Good luck.
Hth.

15k and they are shot is terrible. Toyo did have lots of trouble with these tires. Check this site for more info-sounds like you will have to fight like heck to get them to do anything though. Good luck'

Toyota didnt make the tires, so I would not think they would. Contact TOYO. but I doubt they would either. Car Manufactures do not put the best tires on, they send out for bids, and the tire company with the best bid wins.

All car manufactures do this 30,000 mile tires only to add 4 tires that cost 100.000 each and sell 1000 cars would cost them 40,000 dollors and a million times 4 would be 4 million times 100.00 dollars you get the picture? 40 million dollars for tires. When I got my new truck I ordered better tires and it cost me $150.00 to upgrade to 50,000 tires. you pay for what you get.

Take your copies of the orignal complait to them if they do not fix at no cost tell them you want to turn the car in and get your money back, you will get some action. Same thing happened to ford over 2 PSI per tire what hog wash!

Contact the Toyo company. toyota will not help you on this one. You need to check to see if there is unusual shredding or peeling or possibly chunks coming off the tires. That is what happened with mine at 14K miles and I am in the process of getting them replaced. Toyota service told me they thought it was normal wear. It was not. After I contacted Toyo, they told me to go to a toyo dealer and have them call the company back. They offered me 100% if I put the same A20 tire onthe vehicle and 70% (100% for unused spare) if I put the new Toyo HT. I chose the latter since it has a 60K mile warranty. What I also found out is the A20 tire is not the same one you can buy now. The new one is the A20A. The original A20 was made specifically for Toyota at their request as an OEM tire. Toyota should have some liability in this and I am fighting them for the 30% cost, but am not holding my breath they will help.
Then only manufacturer of the 245/55R19 is Bridgestone and Toyo at this time.

I'm surprised if it's so good at braking that it has not ripped my entire tire tread off as technicians say the treat is separating well before its time!
