Default Toe/caster adjustment after 35"

I should have my 35s tomorrow and Im questioning if Im going to have to make adjustments on my front alignment.

I have done a search and I see some people saying yes and some saying no adjustments needed.

I'm still on stock suspension with those exact tires and aftermarket 17x9 -12mm wheels. It looks like I have some toe out now and it pulls to the left slightly. Waiting til I install 1" spacers all around before doing the alignment.

I had Toyo 35's put on my 2012 Rubi with a 2.5TF coil lift but added track bars front and rear to re-center the axels. I had the installer do an alignment. Then I noticed the jeep was pretty "jumpy" on the road. Fixed this with Lower Control Arms and asked them to bring the castor to "stock" and specified this was about 4.5 degrees. Jeep seems to be running well now back to what I would say it was before I lifted and changed wheels/tires.
I am very sensitive to changes in steering, and noticed a change even with my mild lift.
I had a shop do the work, but there is certainly more than enough information on this forum to walk anyone though it. Since I don't do this sort of thing, I paid to have it done. However, the information needed to know what to ask for was invaluble.

he was asking about toe, not caster. Toe should be fine with 35's...usually only needs adjustment above 37's

Put the tires on and see how it drives.


The Toe won't change, and should not need to be adjusted.

The Caster won't change. It should be set for the new lift height, not the new tires. (you will need to add cams or new ca's if you decide to adjust this.)

The Camber won't change. If this is off, you likely have problems that an alignment won't fix.


So again, slap the tires on and see how it drives, then decide if anything needs tweaking.

This is a good write-up to familiarize yourself with what's going on.
