So to speak...

Bought new tires at 30K miles for my 08 GS350 - Michelin Pilot Sports. OEM size.

Car now pulls hard to the right. Car was in for service and I went ahead and had them align it. Still pulled hard to the right so I went back. They agreed, and at the end of the day said I had a bad tire. They determined this by switching the left front with the right and the car tracked straight. The tire dealer gave me a new tire. Put the tires on the correct sides and the car again pulled to the right. Went back to the dealer and he put new oem tires from another GS on my car and it tracked straight. They are blaming the "aggressive, chevron" tread pattern on the new tires. Got back from a long road trip this weekend and I took it back to the dealer for service and asked them to look at the pulling problem again. They switched both fronts and backs across the car and it then it pulled to the left. The dealer is done with this and says I have to live with it or get new tires. I only have 5K miles on the new, $1100 tires.

If the dealer is right, how would you ever know what tires to buy, knowing that tires are often discontinued and I keep my cars for 200K milesplus.

Any advice?
