Currently have 20" with 33'' on my truck with 2 1/2 leveling kit and add a leaf in the rear., but i am going to be switching back to my stock 18'' for the winter. Do I need to have my truck realigned when i switch back to my stockers.

Thanks,
Mongo

 

No just changing the tires will not require an alignment. However, it does help to have a regular schedule for that kind of stuff. I have mine done annually, about every 20k.
