Hi guys. You mentioned the struts and shocks. Those have nothing to do with ride height. It's sagged coil springs that must be replaced. That's where measuring ride height is important. Along with that, even though the numbers on an alignment computer might show everything is in perfect alignment, that is only for a car that is sitting still on the hoist. For a car in motion, the suspension geometry must be correct, and for that to be true, ride height must be correct. A conscientious alignment specialist will not align a car that is sitting too low because there IS going to be accelerated tire wear and poor handling. Only new springs will solve that. Many mechanics save their customers money today by installing new struts with the new springs already installed. Parts cost more but installation time is cut a lot.
Taller tires will add all kinds of new problems including rubbing, especially if the car is already sitting too low. The speedometer will be wrong. You'll also affect an alignment angle called "steering axis inclination", (SAI). That will adversely affect handling, steering response, braking distance, and comfort. Your steering is already very tiring on long drives because it is "busy" by responding to every twig and pebble on the road. Changing SAI will aggravate that to the point you won't want to drive the car.
