Alignment differences between 17, 20, and 22 in wheels?

[zzrsouth]

Wondering if anyone knows or has experience with alignment issues putting 20 or 22 in wheels on a T1 that came with the base 17s.

 

I typically switch between summer and winter wheels every year in my vehicles but I've read the factory alignments are different for the T1s with the larger 22 in wheels.  Don't want to invest in some 20 or 22 inch takeoffs for summer wheels and find out they dont drive well with 17" base wheel alignment.  Anyone done this?

They come with different specs for different wheel sizes, the larger wheels usually effect the ride height while most of the Other specs usually remain the same But changing the ride height will effect the other specs. I can’t verify this on the 2019’s as our alignment machine hasn’t been updated with the newer specs yet.  Overall I think you would be alright your not changing suspension parts.

whats really crazy is the super car specs they will specify a tire brand for alignment specs.

On the T1, alignment specs are based on 2wd/4wd/Trail Boss for suspension options, and then by cab configuration.  No difference in specs for wheel/tire combo on the truck.

 

-Z7X is 4x4 without Trail Boss, +Z7X is 4x4 with Trail Boss.

That's correct.  You're aligning the suspension not the wheel.  As you say, no different specs for wheel size.

K2 trucks had specs based on the wheel/tire package.  GM has done it before.

Looking at some 22in high country take offs tonight for my plebeian Double cab LT.  Will report back if I pull the trigger.

Yea really not sure why.  I put larger wheels on my '14 and '16.  Checked alignment after and was spot on.
