Here’s a hot topic for you and the B&B. I have a 2006 Sienna LE (front wheel drive) that has been absolutely bulletproof and reliable for the past 140k miles, except for the tires. I run “all seasons” in the summer and winter tires on separate wheels in the winter. We drive about 10k miles in the summer and another 5-7k in the winter. We live in the Finger Lakes region of NY.
I own an 06′ Hyundai Elantra GLS hatchback and tire wear on the front left tire has been much worse than the other three, despite rotating the tires. The outside of the front left tire is worn down so that it is smooth and now I can see a secondary layer of rubber being exposed. At first I thought maybe there was something wrong with the alignment but I took it to three places, one wanted to charge me a $90 “diagnostic” fee so I walked and the other two couldn’t find anything wrong. One place mentioned that since I had directional tires I couldn’t really get a proper rotation and thats probably what’s causing the wear.
