Thanks for the advice though, I had no idea what to do.
Incorrect, there are directional tires, I have a set on my car. The sidewall does not say lt/rt but it does have a directional arrow stating such.
You don’t set a car’s alignment based on the tires. The alignment is set according to guidelines and specs from the manufacturer of the car. If the alignment is set correctly and the tires are good, you should have a car that tracks straight going down the road.
That’s what I thought too, but on the previous alignment everything was set to the factory specs, then after the installation of new tires, the car was put on the rack and some of the specs had changed.
