How to align your Jeep Wrangler TJ

Who is going to fix the first post? 🤣
Total, and if spec in FSM is total, then the range is 0.18-0.42* And total toe in for 1/16” would bring you inside at 0.246* for a stock tire.
We’re in agreement.

i nominate @Jerry Bransford
I think you're flipping it now. The spec is 0.30 degrees. At 30" that's closer to the 1/16 difference between the front and back. At 35" that's closer to 3/16. It seems you're backing into this one with inches and tire size?
Nope. I just used the other calculator to help @JMT realise that he doubled his result.
As a synopsis, so we don't confuse the matter any further:
30" tire
0.30 degrees total = 0.15"
Range:
0.18 degrees total = 0.095"
0.42 degrees total = 0.22"
31" tire
0.30 degrees total = 0.16"
Range:
0.18 degrees total = 0.97"
0.42 degrees total = 0.23"
33" tire
0.30 degrees total = 0.17"
Range:
0.18 degrees total = 0.1"
0.42 degrees total = 0.24"
35" tire
0.30 degrees total = 0.18"
Range:
0.18 degrees total = 0.11"
0.42 degrees total = 0.25"
etc
Now just add to your post the fractions so we can use our tape measure. LOL
5/32” is close enough for a 30 or 31” tire
11/64” for a 33” tire
3/16” for a 35” tire
This is a good argument for going to 35” tires. 😂
If you used a couple of spacers from the tubes to the rim you could leave the tires on. The spacers would have to be the same length. This is how alignment machine heads attach.
This is the best solution. It’s a one size fits all if people will remove the tires.

Both the front tyres on my (new to me) 2001 were absolutely cooked - swapped them out for new Dick Cepek Extreme Country 31's and declined the $150 alignment offered by the tyre dealer. The toe in was set to 20mm by the previous owner. I used a couple of lengths of square tubing and set the toe in to 5mm and the difference in ride and steering was immediately noticeable. Thanks for the thread! The tyre dealer was going on about having to set the caster and the camber and it was a complicated process to align everything - what a load of BS!
I'm doing a front upper/lower arm swap out including the upper frame mount bushings as well as a new adjustable trackbar as some of the bushings look a bit worn - not terrible by any means but cheap insurance against a new set of tyres.
Anyone want to hazard an opinion as to whether that uneven wear was mostly due to the toe-in being far too aggressive?

Oh and that's the driver's side tyre - the passenger side tyre was even worse - almost completely smooth on the outside...
