My 99 E430 Sport has an unusual tire wear pattern. Both front tires show wear on the inside. Both rear tires show wear on the outside. The steering wheel is striaght when travel on the level highway. The car has completed 58k miles without alignment since its birth. Everything on the car is factory without any modification.

I am going to buy 4 OEM size tires next week. Do I need an alignment? If so, should I go to dealer or my local NTB? Is there any special tool at the dealer that will increase the accuracy and precision of the alignment?

Thanks
