WOW! Did I have a flashback when I read your "soap opera" about your defective tires on your 2010 Toyota. I went through the
SAME thing for 10 1/2 months back in 1999 with my Motor Trend "Car of the Year" Chrysler 300M! What a piece of CRAP! To make a
VERY long story short, the dealer is right about
ONE thing- the tires are warranted by the tire company. Call CORPORATE HEADQUARTERS for the tire company ASAP and explain the problem. Tell them that you want to take it to a factory authorized dealer near you to get the tires checked out. Like me, I am SURE that you drove over the same roads with your previous vehicle and never had a problem with the
"crown in the road"! That is their BS! They
ALL try to give their customers the same BS as if we were ALL idiots!
My defective tires were Goodyear LS's. I had thousands of miles on my tires because I gave 3 dealers a chance to correct the problem on their own before I took matters into my own hands! They rotated the tires God only knows how many times. They replaced the rack and pinion steering etc. I had this whole soap opera written out at Yahoo GeoCities, but they no longer have GeoCities and the site was deleted.
Anyway, STICK TO YOUR GUNS! DON'T GIVE UP! That's EXACTLY what they want you to do. If the tire company doesn't help you, which would surprise me, then call Toyota CORPORATE HEADQUARTERS and NOT "customer service"! They are MORE useless than the dealers. The "factory reps" are JUST as incompetent!
I hope this helps. PLEASE post here again when you solve the problem or keep us informed as to what is going on. Good luck.
