Default Do I need to realign?

Hey guys I'm thinking about jumping to a slightly taller Tire front and rear, going from a 25 to a 30, & from a 30 to 35. I'm guessing I'll have to realign it after I reset my ride height?

That shouldn't affect your alignment.

Are you talking about adjusting ride height using the screws in the springs after you install the new tires? Or, are you talking about the taller tires affecting ride height? If the first then you do need to realign, if the second then you don't.

as of right now it's lowered all the way on the stock bolts, ZO6 with the zo7 package, hoping I won't have to touch those lowering bolts again after I install the slightly taller tires. I believe if I go 5 higher on the tires it will be about an inch and a half taller Tire, so I'm guessing half that amount will fill in the wheel gap. Does that sound about right? Thanks for your help!

great info, surprisingly the tread width on 345 is not as wide as the 335? Forgive me for asking, what does the section width mean? So if I'm understanding this right, the 335 run-flat tire is wider ( more rubber touching the pavement) than a 345 non run-flat? Thanks for your help Bill
