Wheel & Tire c/o>> Front End Alignment?

Now that I have completed my 3" ToyTec lift, I have a suspension question. If I go from a 16x7 wheel with 265/70's to a 17x7.5 with 285/70's, does that change the front end geometery that I should have a front end alignment done??? The reason I ask is that I just did a 3" ToyTec lift and still have my stock wheels and tires on. I plan to change over to FJ wheels and tires soon and don't want to spend the $$ on 2 alignments. Can I do the alignment with the stock setup and when I switch over to the new wheels/tires be OK??? The camber is way out now as one would suspect. Thanx

 

Putting on a 3" Toytec lift next weekend..... never lifted a truck before and don't know much about it.....

Need to get a new alignment huh? i guess it is a dumb question just didn't realize i had to....

 

Bigger tires won't usually require an alignment, but any time you lift the front or mess with the geometry you must get an alignment performed.
