Default Bigger tires! Different alignment specs?

Ok. So my wheels and tires have finally made it to my shop. My question is.... With the tires, 35x12.50-18, will my toe need to be adjusted to compensate for the change in scrub radius? In thinking no, but at the same time it seems as though it would effect the friction points on the tires. I'm going from stock sizes and stock back spacing to 35" with 4.5" BS. I'm thinking the thrust angle and scrub radius should remain close to stock since it will move the scrub further away and out from stock. Am I overthinking this?

I just had my alignment checked after doing my lift and 35's... NTB does free checks btw, the tech said it was so close he would leave it as is and save me the $90 charge.

Worth the effort to have it checked at least.

Was wondering if a deviation from STOCK would benefit the a Jeep. I know that currently it is in stock spec except caster. It's set to the lift companies spec. Just didn't know if more toe, or less toe would be needed.

I would have the toe adjusted as that will wear a good set of tires down quick. Castor should be an issue and we can't adjust camber being solid axles and all

You might want to increase toe. Factory I was almost 1/4 in.
1/8-1/16 to even 0 with a 35"
