Don't quote me on this...but my grandpa swears if your alignment is fine when you go in to have new tires installed, don't let them sell you on their "free alignments" because it's unnecessary.

Although if you do it yourself...it'll be free and will only cost you a little of your time. Run a search for a basic front end alignment. For Jeeps under like 6" of lift, all you need to do is set your toe-in which can be done with basic hand tools and a tape measure. You'll also probably need to adjust your drag link to re-center your steering wheel if you haven't done so already.

if you go from 30s to 33s with the alignment from the 30s, you'll have too much toe-in. will it matter? probably not...depends how "loosely" they put it within spec.

I was talking with a long-time Jeep Liberty owner yesterday. He has owned a YJ and some CJs in the past. He said that "front end alignments aren't necessary." I'm assuming staying with the same size tires.

Can you tell me more about what he meant by that?

He's probably talking about the fact that with solid axles, you can't set the camber and caster (not usually). You still need to set the toe in. Fairly easy to do.

If I do anything to the suspension, imma get it aligned, I just put a "leveling kit" on front of wife's commander and instructions said it did not need aligning with the 3/4" lift, but the 2" lift DID need aligning, so out of curiosity, I did it and shop said it was out "a good bit"

Changing tire sizes or brands wont affect alignment, but if you change the angles of the steering components( basically triangles) you need it, like adding or removing alot of weight up front. Example, if you go off and buy a 200 pound bumper and a 75 pound winch, it would be smart to spend the $40 and get it aligned

Keep in mind Liberty's, YJ's and CJ's use a completely different steering and suspension setup from a TJ/XJ/ZJ.

He might have good intentions, but it doesn't sound like he knows enough about TJ/XJ/ZJ steering & suspension to tell you an alignment isn't necessary on your Jeep.

TJ's absolutely need alignments after a lift. Theres four main things to consider - steer ahead, toe-in, camber and caster. Steer ahead is whether the steering wheel is centered or not, and is adjusted at the draglink. Toe-in is easily set at home on the tie-rod, in your driveway with a tape measure. Caster is set by cam bolts on the lower control arms, or with adjustable lower control arms. Making the lower arms longer increases caster...stock caster spec is 6-8 deg. if caster is poor, the jeep will drive squirrely and the return to center of the wheel will suck. Camber is NOT adjustable on a solid front axle without off-set ball joints. If your camber is off significantly, it can suggest a bent or warped housing. Caster and camber are both measured best on a laser alignment rack.

If you do a lot of suspension work, and you really want to dial the alignment in so the Jeep drives the best, look into a lifetime alignment from Firestone. I've got one, and i've had the Jeep aligned nearly 10 times in the past 3 years or so. Multiple trips to Firestone after axle swap, steering upgrades, lift height changes, caster changes, etc allowed me to get the steering and suspension dialed in very well.
