Even if you replace your front tires with a new set exactly the same brand and size, front end alignment is always recommended. Interestingly, the last time I took my car to get an alignment, ( new tires ), the "high tech" shop didn't have the proper adaptors to fit my 14" factory rims, so I had to hunt down a few shops until I found a place that could do it. Back when, alignment was accomplished with the front tires resting on turntables which aided with toe-in, today, many shops have laser targeting devices which attach to the rims and shoot a mark onto a target board. They can also check your rear axle alignment, not that , for most of us, this is an issue.
